Beko B13, B7S, B7SLED Washing machines - How to enter the service mode, Error codes and details, main components functions and ratings, wiring diagram

Electronic Control and Visual Card

By means of the control and visual card which is designed to have a single face and manufactured by ARCELİK; the wash programs which are written onto the microprocessor, washing and spinning motor profiles, protection algorithms and components (motor, heater, pump, valves, door safety lock, NTC, water level selection switch, spinning/temperature selection potentiometer) are controlled.
There are feeding circuit on the front face of the card (SMPS), motor and other component control circuits -triac and relays - and component connection terminals and on its rear face there are microprocessor, function and time delay button and LEDs and program tracking LEDs.
Necessary wash program is operated in line with the information read from the program selection switch which is connected to the card (rotary switch), spinning/temperature setting potentiometer, auxiliary function and Time Delay switches.
From the card, auxiliary function, speed/temperature and time delay options and functions can be selected.

Safety Switch (Door Lock)

Rated Operating Voltage	: 250V 50-60Hz
Operating Current	: 10-50 mA
PTC Resistance Contact Locking time Contact Engaging time Operating Temperatures	: Min. >=50 ohm : <=8s : 35...70s : T85

PTC door safety lock was used. When any wash program is started after the door is closed, PTC disk is heated and the door is locked and it is prevented to be opened when the program is in progress.
After the program finishes, PTC cools down in 70s and the door is unlocked.
Current of all components passes over the door safety lock. Machine will not work in case it is faulty.
When 220V is supplied between the contacts numbered 3 and 1, the distance between the contacts numbered 3 and 2 should switch to closed position.

Motor
Universal series motor is used. Universal series motor consists of stator and rotor. Stator and rotor windings are connected in series by means of collector and brush and current is transmitted to the rotor windings. Motor speed control is made over electronic card. Motor triac on the card adjusts the motor/drum speed by changing the triac triggering angle according to the signal coming from the tacho. In case of abnormal situations (continuous operation-locked rotor), thermocouple is available on the motor winding to protect the winding from overheating.

Rated Operating Voltage	220-240V 50-60Hz
Current	6A max (washing) / 3A (spinning)
Input Power	300 / 450 W
Starting Current	5...8A (washing) / 10A max (spinning)

Technical specifications of tachogenerator

Number of double pole Tacho output voltage at 300 rpm >0.9 V Tacho output voltage at 16500 rpm	8
<45 V

Heater
It is used to heat the water inside the drum.
Since it is an electronically controlled machine, there is a double thermocouple at each of the heater inlets.
When the heater operates dry, the overheated thermocouple open circuits the heater.
Open circuited heater cannot be used again. In order to prevent the heater to operate without water “during heating”, heater safety water level is defined to the microprocessor (Psafety). When the water level which is measured by the water level sensor comes under the defined Psafety level, heater is disabled.
When the water temperature which is read by NTC reaches to the “selected temperature”, heater is disabled by the microprocessor. 

Operating Voltage : 230VAC 50-60 Hz

Power : 1950W
Resistance : 26W ± 3W

When the resistance is measured from both ends with multimeter, approx. 26W should be read.

Valve
There is 2-way valve in the models which have a single water inlet and there is 2-way valve and extra single valve in the hot-water inlet machines. Valves are driven by the triacs on the electronic board; and they are driven with both valves in the softener step by use of crashed water directing system and the water is directed to the medium compartment of the detergent dispenser.

Rated Voltage	220-240 V 50/60 Hz
Rated Power	5-8 W
Winding Resistance	3400-4500 ohm
Flow	10 l/min

Drain Pump

It is a synchronous motor equipped with a mono-phase bipolar magnet rotor. At the draining step, electronic control card is activated by the triac on it. It is protected by impedance for continuous operation and blocking situation of the rotor.

Drain pump drains the water inside the drum.

Rated Voltage	220-240 V 50Hz
Resistance	145 ohm
Current	<0.2A
Flow Starting performance	>14 l/min <=4s (160V)

NTC
It is a component which is used to measure the water temperature inside the drum and resistance of which decreases when the temperature increases.

Resistance values which are read from the NTC ends by means of multimeter are compared to the below table. These approximate values should be read.

Resistance	(25 °C)	: 4773 ohm (±4.2%, Siemens)- 4837 ohm (±3.2%, elth) : -10°C...+100°C : 16 ±2 s
Operating Temperature Thermal time constant

Water Level Sensor

An analog water level sensor which is fed by 5 V voltage is used. This sensor ensures that the water level is determined instantly with the frequency values which it generates against the pressure created. There are frequency values corresponding to the all pressure values. An infinite number of levels can be determined in the analog water level sensor. Water levels change according to the wash criteria of the designed program depending on the selected program, temperature and auxiliary function.
Analog water level sensors are pressure – displacement inverter components in general.
Analog water level sensors generate frequency modulation as output. There are basically 2 capacitors, 1 coil and an inverter circuit on itself or the control system to which it is connected. Pressure increase pushes a ferrite part inside the sensor into the coil. Therefore L (inductance) value of coil winding changes and the output value of the sensor – inverter system changes. Therefore pressure value can be measured in an analog manner. 

The amount of water to be taken in for the programs is controlled by the water meters. Water level sensor serves the basic functions of deciding to take in water again, control the heater safety level, door opening level or foam level.

Also, if there are any error in the water meters or its connections, water is taken in with the water level sensor.

When it is empty, 625 ± 2 Hz frequency value should be read from the Data and GND terminals.

Cable inputs
5VDC / Data / GND. Operating Voltage : 5 VDC

Error codes details

Service mode and details

Entrance Method to Service Mode: 

* By pressing the “Start/Pause” button, you can switch to “Service” mode when you turn the button to the first program from the rotary “ON/OFF” position CW.

* To activate the components which are controlled in each step of the service mode, the door has to be mechanically locked, that is, components must be powered. For example, to rotate the motor, the door must be locked, in other words motor must be energized.

* After the service mode is entered, if door contact is not closed for any reason (door lock is faulty or door lock triac is faulty), that is electronic card is energized but the driven components (heater, motor, pump, etc.) are not:

a) In Models with LED: "Ready" follow up LED will be lit steadily. In the meantime, if EEPROM has a "Error Code", they will be coded at "Spin Level" LEDs (in decimal system (BCD format)).
If there is no error, all of the "Spin Level" LEDs will be turned off.
Also, if "Start/Pause" button is pressed, then no change will take place in the above mentioned issues and as the door is not locked in real "Service Mode" steps will not be progressed and "Error Code" will be shown steadily. 

b) In 7S models : If you have an "Error Code" on EEPROM, this will be shown on 7S display as "E?"
If there is no error, "E--" will be shown on 7S display.
Also, if "Start/Pause" button is pressed, then no change will take place in the above mentioned issues and as the door is not locked in real "Service Mode" steps will not be progressed and "Error Code" will be shown steadily.

* The energy of the machine is interrupted due to any reason whatsoever at any stage of service test (due to “ON/OFF” or power cut), WM goes back to "Selection Mode" when it is energized again.

If more that 2 minutes are waited at a service test step, WM goes back to selection mode.
At the service mode, components are activated one by one by pressing the Start/Pause button. In turn:
1) At startup, “Error Code” which is created last and recorded to EEPROM is shown.
Following points should be paid attention when “Error Code” is displayed:

In 7S Models
If there is an “Error Code”, counterpart of this code in the decimal system (in BCD format) is displayed on 7S by adding “E” to the beginning. Example; “E09” or “E13”.
If there is no “Error Code”, this is displayed on 7S as “E--”

Only in Models with LED
If there is an “Error Code”, counterpart of this code in the decimal system (in BCD format) is encoded to the “Spin Level LEDS". When encoding is performed, weights of the orders from the bottom to the top are as follows 20=1, 21=2, 22=4, 23=8 Hertz in turn. For example, if the "Error Code" is "03" then the bottom most 1st and 2nd LEDs will be turned on while others are turned off. If the "Error Code" is "08" then only the 4th LED from the bottom will be turned on while others are turned off.

If there is no "Error Code" then all LEDs should be turned off. Next step is taken by pressing the "Start/Pause" button;

2) "Error Code" and other information stored in EEPROM (point to resume) are deleted from EEPROM and in 7S models 3-digit software version is displayed, and to switch to the next step "Start/Pause" button is pressed; Only in Models with LEDs the next step will be automatically progressed (without pressing "Start/Pause" button).
3) By flashing all segments of 7S and all LEDs "Display" test is realized.
When "Start/Pause" button is pressed, all segments of 7S and all LEDs are turned off to end "Display" test and switch to next step;
4) Turned for 52 rpm to right (CW). Meanwhile, in 7S models, "4", which is the "service mode step number" of this step is displayed. In Models with LED, of the "Program Tracking LEDs" above the "Start/Pause" button, the 3rd LED from the bottom will be turned on (weight of orders from bottom to top are 20=1, 21=2, 22=4, 23=8, 24=16); Next step is taken by pressing the "Start/Standby" button;

5) Turned for 52 rpm to left (CW). Meanwhile, in 7S models, "5", which is the "service mode step number" of this step is displayed. In Models with LED, of the "Program Tracking LEDs" above the "Start/Pause" button, the 1st and 3rd LED from the bottom will be turned on (weight of orders from bottom to top are 20=1, 21=2, 22=4, 23=8, 24=16);
Next step is taken by pressing the "Start/Standby" button;
6) In the previous movement, motor movement is stopped and following checks were performed and tester was informed in different ways: If the Water Level Value read on the Water Level Sensor is out of the limits (if Water Level Sensor socket is properly fitted or if it is loose), next step "7" is taken. This way, there is not any drum movement in step 6 and if step 7 is taken automatically, person making the test will sense this condition as "Water Level Sensor Error" .
b) although the Water Level Value read on the sensor is within the limits if it is above "Safety Level", pump is operated and when the level drops below the "Safety
Level" basic controls of this step are carried out (meanwhile drain pump is active).
These are, in the order of priority

1 If there is NTC error, 100rpm is applied;

2 If there is no NTC error, but if the values read at Line Voltage Reading Inlets (Line_Voltage_ADC) are below 185 Volts or above 265 Volts, 140 rpm is applied. This
error could be caused by two conditions:
Either the ADC inlets of microprocessor are defective or it is indeed out of the line voltage limits.

3 If there is no any NTC error and no error on Line_Voltage_ADC inlets, “MAX_SPEED / 2” "MAX_SPEED" rotation is applied."MAX_SPEED/ 2" (Rev03_28112012):
Modified as MAX_SPEED. Meanwhile, "6", which is the service mode step number is displayed on screen of 7S Models;
In Models with LED, of the "Programme Tracking LEDs" above the "Start/Pause" button the 2nd and 3rd LEDs from the bottom will be turned on (weight of orders from bottom to top are 20=1, 21=2, 22=4, 23 = 8, 24 = 16);
Next test step is taken by pressing the "Start/Pause" button.
7) Motor movement which is started in the previous step is stopped and pump is shut.
“PRE_WASH_VALVE” which is the main test of this step is opened and checked.

Meanwhile, "7", which is the service mode step number is displayed on screen of 7S Models;

In Models with LED, of the "Programme Tracking LEDs" above the "Start/Pause" button the 2nd and 3rd LEDs from the bottom will be turned on (weight of orders from bottom to top are 20=1, 21=2, 22= 4, 23 = 8, 24 = 16);
Next test step is taken by pressing the "Start/Standby" button.
8) “PRE_WASH_VALVE” which is opened for test in the previous step is shut.
“MAIN_WASH_VALVE” which is the main test of this step is opened and checked.
Meanwhile, "8", which is the service mode step number is displayed on screen of 7S Models;
In Models with LED, of the "Programme Tracking LEDs" above the "Start/Pause" button the 2nd and 3rd LEDs from the bottom will be turned on (weight of orders from bottom to top are 20=1, 21=2, 22=4, 23= = 8, 24 = 16);
Next test step is taken by pressing the "Start/Pause" button.
9) “MAIN_WASH_VALVE” which is opened for test in the previous step is shut.
“SOFTENER_VALVE” which is the main test of this step is opened and checked.
Meanwhile, "9", which is the service mode step number is displayed on screen of 7S Models;
In Models with LED, of the "Programme Tracking LEDs" above the "Start/Pause" button the 1st and 4th LEDs from the bottom will be turned on (weight of orders from bottom to top are 20=1, 21=2, 22= 4, 23 = 8, 24 =16);
Next test step is taken by pressing the "Start/Pause" button.
10) “SOFTENER_VALVE” which is opened for test in the previous step is shut.
"HOT_WATER_VALVE" which is the basic test of this step is opened to check if available
on the machine being tested (if no hot water valve is available, this step is automatically skipped").
Meanwhile, "10", which is the service mode step number is displayed on screen of 7S Models;
In Models with LED, of the "Programme Tracking LEDs" above the "Start/Pause" button the 2nd and 4th LEDs from the bottom will be turned on (weight of orders from bottom to top are 20=1, 21=2, 22= 4, 23 = 8, 24 = 16);
Next test step is taken by pressing the "Start/Pause" button.
11) “HOT_WATER_VALVE” which is opened for test in the previous step is shut.
HEATER test which is the main test of this step is conducted as follows;

If the Water Level Value read on the Water Level Sensor is out of the limits (if Water Level Sensor socket is properly fitted or if it is loose), next step "12" is taken. This way, if there is not any increase in power in step 11 in terms of washing machine consumption and if step 12 is taken automatically, person making the test will sense this condition as "Water Level Sensor Error".
(Rev02_07102011):
b) Although the Water Level Sensor readings are within limits if the water level is below "Safety_Level + 20 units" then all valves will be opened to top up the water level.When the water level exceeds "Safety Level + 20 units" the open valves will be shut off automatically. After this stage there are 2 conditions:
i) On a machine without "Main Wash Flow Meter":
HEATER is turned on automatically and 52rpm is applied to right. (With REV_04, 52 rpm to right at Heating step is removed.) Tester checks whether there is an increase in the power which is consumed by WM and check heater.
ii) On a machine with "Main Wash Flow Meter":
"Main_Wash_Flow_Meter" will be checked to see if it is higher than "50" or not.
If it is higher than 50, then Flow_Meter is operating correctly; HEATER will turn on automatically and a 52 rpm right turn will be applied.(In models with flow meter, there is motor movement) If it is below 50, then the Flow_Meter is faulty and therefore the heater will not be "DRIVEN" and proceeded to the next step of the service mode ("step_12").
In this way Flow_Meter error will be identified.
Meanwhile, "11", which is the service mode step number is displayed on screen of 7S Models;
In Models with LED, of the "Programme Tracking LEDs" above the "Start/Pause" button the 1st, 2nd and 4th LEDs from the bottom will be turned on (weight of orders from bottom to top are 20=1, 21=2, 22= 4, 23 = 8, 24 = 16);
Next test step is taken by pressing the "Start/Standby" button.

12) “HEATER” which is opened for test in the previous step is shut. Also, the motor movement which is started in the previous step is finalized and all valves are shut.
“PUMP” which is the main test of this step is opened and water inside the WM is drained below "Safety_Level". When the water level comes below “Security_Level”, pump is shut off.
At the beginning of the drain process, MAIN_WASH and HOT_WATER valves will be turned on for 5 seconds (Rev01_22072011)
Meanwhile, "12", which is the service mode step number is displayed on screen of 7S Models;
In Models with LED, of the "Programme Tracking LEDs" above the "Start/Pause" button the 3rd and 4th LEDs from the bottom will be turned on (weight of orders from bottom to top are 20=1, 21=2, 22= 4, 23 = 8, 24 = 16);
"At the spinning stage, if no error, "turn at max/2 speed" "rule is modified as "turn at max speed"

The 52 RPM right turn movement at the heater stage is removed.
Since this step is the last stage of the service test, if the “Start/Pause” button is pressed for one more time, this will return to step 1.

Service Menu Instructions

    Make sure the set is turned on.
    Press {Menu} + {9} + {3} + {0} + {1}
    You will now be in the service menu of the set.

ARCELIK BEKO LCD TV - TF CHASSIS – SERVICE MODE – ERROR CODES – TROUBLESHOOTING – SOFTWARE UPDATE

Arcelik BEKO LCD TV - TF CHASSIS – Service mode – Error codes – Troubleshooting – software update 

To enter service menu, just like in the previously launched products, we press menu button of the remote control and enter 9, 3, 0, 1 in sequence for BEKO/ARCELIK brand TVs. 

For GRUNDIG brand we enter 8, 5, 0, 0. As the chassis improvement and development works go on throughout the production, service menu items may vary according to the software version. 

The following explanations are service menu settings of the current version.

This menu contains general settings of the system.TV MODE tab contains "Factory" and "Customer" options. It is used to perform factory controls and settings more efficiently and faster. On the TVs delivered to the customer, this setting is absolutely selected as "Customer." Otherwise, it will lead to customer complaints such as "TV automatically turns on after power failures" or "different functions operate from the remote control".

HDCP VERIFY: It must be checked if HDCP key is loaded or not during factory controls. HDCP key stands for ““High Bandwidth Content Protection Key”. This key is used to prevent copying of data on digital sources such as DVD or blue-ray. With HDCP, video data is transmitted from the source to the receiver as encrypted. Therefore, to watch HDCP encrypted DVDs or blue-ray, HDCP key should have been loaded on TV. On the products with HDCP installed, SUCCESS message is included.

DEBUG MODE is a feature, which is used to track software modifications made on TV during R&D stage. This setting must be "Off" on TVs delivered to the customer.

PLUG PLAY (Demo Mode): A navigation key is pressed after having completed all settings and checks in the factory. Later, "Please wait" message appears; and when you see the message "DONE", the device should be unplugged and plugged again. With this process, television will be set to its initial values before delivery. It will be proper to set Plug&Play tab after servicing. After pressing right key on the tab, EEPROMs will be loaded with factory defaults. TV can be shipped to the customer after this setting. Please note that any warning is not displayed or you do not have to exit the menu while Plug&Play is getting activated. You should be careful not to take the device into Plug&Play mode by mistake.

ATS (Automatic Tuning System) tab ensures that the channels are arranged in order after automatic search. However, there is a broadcast support to order the channels. It is active when “On” is selected. “On” should be selected in TF-chassis products.

SRS (Virtual multi-channel sound system) turns on and off SRS Tru-Surround XT HD feature. SRS Tru-Surround XT creates a sound experience surrounding the user similar to 5+1 sound systems, thanks to multi-channel audio by using two loudspeakers produced by SRS company. SRS is an optional feature that can be selected upon the customer’s request. BLUE BACK enables us to determine background when there is no picture on the screen. When "On" is selected, background will be blue; and when "Off" is selected background will be black or snowing. “On” should be selected in GRUNDIG brand products and “Off” in other products.

HOTEL tab should be set to "On" on hotel TVs, and it should be set to "Off" in other products. When the hotel model is "On", certain features designed for the hotel use are activated; the user cannot change the channels set by the service, for example, or the volume cannot be increased more than a certain level.

CI KEY VERIFY indicates if CI Key has been installed or not. This menu cannot be changed. This option should appear as “Pass” in the products with CI Plus feature. CI Key is the keyword on the card which is inserted to decrypt the broadcasting. This menu is a control indicator and changes automatically. This keyword is installed during TV production and it becomes a kind of ID for your TV when watching encrypted channels. TF-chassis products support CI+ feature. Launched in 2008, it is a new encryption standard developed with the collaboration of consumer electronics and scrambled digital broadcasting companies. So far, it was possible to copy the programmes after decoding process; however, now they cannot be copied thanks to that main IC coming with the CI Plus has a key. In this system, broadcasting is initially decoded on CI card. The broadcasting transmitted to the main IC from the CI card is also encrypted and it is decoded with CI Key, which is a factory setting and different for each TV. Thus, there will be no free encrypted broadcasting on the bare line and encrypted broadcasting cannot be copied. C+ feature is standard in all the products with TF chassis.

The settings under source configuration tab determine which sources will be on and which ones will be off depending on customer demands. In the small size products, HDMI3 and HDMI4 are off in standard (NAVAIL); and the sources of DVD and USB can be adjusted optionally. In large size products, DVD will be off in standard. In the products with LOW feature, USB, HDMI2, HDMI3, HDMI4, AV2, COMPONENT and DVD sources will be selected off. 

TV Configuration:

This menu contains configuration settings of TV. We may select amongst the menus that are being used and to be used on TV. These settings differ from the "System Configuration". This menu contains the changes which the user can directly observe.

To enter this menu, you should go to "TV configuration" from the service menu and enter the numbers 2, 3, 5, 6 in sequence. TUNER menu contains the tuner types that can be used on TV. TF chassis currently works with “Alps” branded tuners. DVBT2 (Next generation digital terrestrial broadcasting modulation) can be selected as ON/OFF depending on the customer preference, in the countries that support DVBT2 digital terrestrial broadcasting. DVBT2 is selected OFF in the products to be used in the country. In our country, TRT makes DVBT2 test broadcasting in Ankara. OSD Selection menu has "Grundig", "Beko", "Arcelik" and "OEM" selections. For Grundig products, “Grundig” is selected. This selection adds Grundig sign next to the user menu and remote control selection is “TP3”. TV brand should be selected in Beko and Arçelik products. This selection is automatically “YB1187R” in the remote control and several brand-specific menus are also added. For other brands, OEM should be selected. If the product is "Grundig", you can enter service menu by pressing "menu 8 5 0 0" keys. If "Beko", "Arcelik" or "OEM" is selected, you can use "menu and 9 3 0 1" keys.
Note: In the smaller size (19”-22”) products with TF chassis, when Arçelik, Beko or Grundig is selected under OSD selection tab, different remote control options will be displayed compared to large size products.

USB RECORDING menu indicates the television's status of USB recording. It may be selected On/Off according to customer demand. REMOTE CONTROL menu displays remote control selections for BEKO, ARÇELİK and GRUNDIG as stated in OSD Selection above. For example, GRUNDIG OSD can support several different models of remote controls and all those models can be seen under the menu. Selection of remote control may vary according to the customer demand. KEYPAD enables you to select which keypad will be used depending on the mechanical structure of the product. 4-Key, 6-key, single-key and “Joystick” options can be selected. If selected wrong, the keys will work in different functions. 6+1 (or joystick depending on option) can be selected for large size products whereas 4+1 is selected for smaller size products and single-key pad module is used for the products with LOW feature. L (SECAM L sound system) tab enables you to select "L" sound system, and it should be "On."

MEMC stands for "Motion Estimation Motion Compensation." "On" should be selected for the products that use only 100Hz panel.

7 SEGMENT DISPLAY should be selected "On" in the products with the indicators, which mechanically display the hour on the front panel. (Not TVs with LED backlight panel!!!) Generally, this feature is used on hotel TVs. ECO TV option: When "On" is selected , eco standards-compliant power consumption is ensured by turning down the backlight a bit.

ECO TV option should be selected ON for all products with TF chassis. LINE OUT (LEFT/RIGHT Audio output): If the product has line out feature, it should be selected “On”. Large and small size products with TF chassis will have LINE OUT feature in standard.

HEADPHONE tab should be selected "On" if TV has a headphone socket. Large and small size products have headphone sockets in standard.

SHOP MODE is used in the first installation at the dealers for purposes of display (Shop Mode and Home Mode screens appear). When Shop Mode is selected, the logos of various features such as CI+, SRS etc., which are supported on TV, appear on top of screen with certain intervals. SHOP MODE should be selected ON for all products. However, when the product is delivered to the customer, TV is switched back to factory settings via PLUG PLAY; and HOME MODE is selected during the first installation at the customer’s place. During the first installation, SHOP MODE is only selected at the dealers for the purpose of display.

3D TV (3 Dimensional TV Technology) is not supported in the products with TF chassis.

CEC allows you to make an HDMI connection between your TV and DVD player or video recorder and control such equipments with the remote control of the television. The products with TF chassis have CEC feature in standard.

OUTPUT POWER is used to select audio output power. Small size products with TF chassis have 3W audio output.

CABIN OPTION feature is used to create best audio performance of the cabin. Bass/treble settings vary depending on options in the existing cabins; the options have been adjusted to prevent cabin resonance and ensure best audio quality. Depending on the cabins, the list of cabin options that may take value from 1 to 7 is constantly updated.

HIDEV MONO (improvement of high audio deviation), is a feature developed to prevent imbalances that may occur on sound carrier signals due to high audio deviation in the country. It is ON for domestic products and OFF for the products sold abroad. OPTIC OUT (Digital Audio Output) feature is generally used to input digital audio to devices such as amplifier, DVD and etc.

OPTIC OUT will be available on large size products with TF chassis and not available on small size products and the products with LOW feature.

Cloner Configuration:

This menu is used to copy your selections, channel lists, user options, satellite settings and service menu settings on TV and move them to another TV. Particularly, when installing TV at the user's home, this feature will save us time as we will not have to tune satellite channels anew.

Cloning can be done from any TV with the same chassis. To enter this menu, you should navigate to "Cloner configuration" from the service menu and enter the numbers 4, 6, 5, 8 in sequence.

Copy selects what and to where we want to copy. TV to USB copies the configuration on TV to the USB. USB to TV transfers previously prepared channel list, user and satellite settings to TV.

Copy item is the name of configuration to be copied. Channel/Video Set selection enables us to transfer channels, frequencies and favourite lists that were already set. Service Set enables us to transfer service menu settings. When installing at the user’s place, this option should NOT be cloned. User Set enables us to transfer user settings (sound, brightness, TV language and etc.).

Start Cloning option starts the cloning process. Whereas TV to USB takes little time, USB to TV causes a short interruption of TV imaging. When TV automatically restarts after installation, its means cloning is completed. 

NOTES: When cloning, you should ensure that both product codes are the same. During both TV to USB cloning and USB to TV cloning, “ALL" should be selected as Copy item. When cloning between different product codes, only “Channel/Video Set” should be copied. After copying, picture settings of TV may show some differences. TV should be delivered to the customer after those settings are checked. From user menu, navigate to “Source settings” => “Program Table” (don’t select) and press 4, 6, 5, 8 keys to display cloning menu.

Bootcode Code Configuration

In the products with TF-chassis, Boot code should be updated before software updating. Boot code update is performed through the steps below.

Step 1: Please copy mboot.bin file into USB memory. (If the memory contains more than one partition, copy the file into the first partition.)

Step 2: Insert USB memory to the USB socket on the side of TV.

Step 3: Wait for 10 seconds for USB memory to be automatically mounted.

Step 4: Open service menu (MENU+8500 (Grundig)

Step 5: In Service menu, select Boot Code Configuration and press OK.

Step 6: If there is no problem, TV will automatically turn off and restart with new bootloader. If there is a problem, TV will not automatically restart.

Software Version

All versions of software and hardware can be seen under software version tab. “URSA version” tab shows the 100Hz software version installed on 100Hz TVs.

This menu is for information only, it cannot be changed. Other Menus: Other menus are closed to authorized services as they are used for R&D studies in the factory.

FAILURE/ERROR CODES

Sound but no picture, and backlight illuminated
this section  basically explain where we need to check if there is "no picture on TV" even though there are not any problems in the panel inverter. Here, we are assuming that chassis is generally in good condition as we obtain sound output from TV. When you cannot determine if the backlight is working or not due to the illumination level in the environment, you are recommended to tap on the TV's front panel lightly; if the backlight is working, you will notice a slight glowing.

Before starting controls and repairs, it is crucial to analyse and comprehend the problem exactly. In this problem, you must make sure if it is originated from the utilized source, if it is a cable connection error or if utilized devices have any problems or not.

Then, particularly LVDS cable on the chassis should be checked for any disconnections, loose parts, dislocations, breaks or ruptures. Likewise, it will be proper to check cable connections of the panel.

Later, the panel power supply (PANEL-VCC), which is transferred to T-CON board through LVDS cable, should be checked on L609 for 100Hz products and on T607 MOSFET Leg 3 for other products. Panel supply for the products with TF chassis is 12V.

If this value of power supply does not exist, the root cause is detected by tracking back from this supply.

Panel power supply is switched with T607 MOSFET (except the products with 100Hz panel). Initially, the input - that is L607 coil - is checked for 12V. If not found in L607, L608 should also be checked. If you cannot detect 12V supply here as well, then the problem is on the power supply side. For the products with 100Hz, L608 coil is checked for 12V. If not, then the problem is on the power supply.

If 12V exists at the input, check the voltage on T607 FET legs. When TV is “ON”, 3.8V voltage occurs on Leg 1 of FET as to be higher than 0V, and supply voltage on Leg 2 is transferred to Leg 3. If Leg 1 does not have voltage, check "TCON_ON" signal on Leg 8 of R654 resistance. Here, if the voltage is High, it means that panel supply has not been turned on from the main integrated circuit or software. This signal remains High while the TV is going out of Stand-By and gets down to 0V, 1 seconds before the picture appears on the screen.

If the panel is supplied voltage over LVDS, it is most likely that picture information is transmitted as well. Even it is not a precise control method to be used during information flow over data lines, the measuring tool detects voltage around 1.2V DC. In this case, it is likely that panel side has an error; if possible, it can be checked by using a different panel or using the same panel with a different chassis.

Besides,you can also consider problems including that LVDS data is not being transmitted to the panel properly, wrong panel EEPROM or software error. You can solve the problem by installing correct software.
Sound but no picture, and backlight not illuminated

Even though LVDS data is printed on the screen, the picture cannot be seen because the backlight is not illuminated. First, cable connections, particularly inverter and supply cables and connectors should be checked.

24V power supply should be checked over inverter cable when TV is ON. When this power needs to be supplied to the inverter unit of the panel, the backlight will not be illuminated if there is not 24V supply. 24V and 12V supplies are switched on by POWER_SW signal coming from the main integrated circuit when TV is ON. In this case, if there is 12V output but no 24V output, then the problem rests in the power supply.

If 24V supply exists on the system; on the Leg 5 of S606 connector, a voltage over 3V DC should be transmitted to the panel. This voltage gives “switch on” command to the panel inverter. This control is provided with “BL_CTRL” and T608 and peripheral materials.

Besides, voltage level that determines brightness of panel lights through Pin 6 of connector S606 should be higher than 3V. Brightness control may vary according to the panel, however, it operates dimly around 0V and completely on around 3.3V. Brightness control is done by “BRI_ADJ” signal coming from the main integrated circuit.

When the "backlighting" tab is dimmed in the user menu, the voltage in the Pin 6 of the connector decreases slowly.

If no problem appears in the checks performed at the chassis, you should consider that the problem might be arising from panel inverter module or the lights.
No Sound

It should be checked that if other sources, cables and devices have any problems. You need to make sure that volume has not been turned down from television settings or mute button is not pressed.

 If there is not any problems, check the loudspeaker cables and loudspeakers on the chassis; fix the problem, if any.

Check if there is sound on the headphones socket. As an amplifier is used, the headphones output is obtained by amplifying EAR_OUT_R, and EAR_OUT_L signals which are sent directly by main integrated circuit through IC502. If you cannot receive audio from headphones socket, those signals are checked from R505 resistor’s pin 1 and 7. If no signal is observed, then there is a problem on the main integrated circuit. If signals are detected, you should check IC502 and peripheral components against problems, and check IC502 supply and whether MUTE is pressed on.

Besides, scart output of TV should be checked for sound. If there is no sound in scart output, power supply of the integrated circuit at position IC800 and peripheral components should be checked at IC800 input to detect AU_DAC0_L and AU_DAC0_R signals which are sent by main integrated circuit. If you cannot detect AU_DAC0_L and AU_DAC0_R signals at the IC800 input, it means no sound signal comes out of the main IC. If the scart output has sound, the problem might be arising from the sound amplifier or peripheral materials

When there is no sound, the pins 2-3 or 34-35 of sound amplifier on IC501 position or L504 is checked for 12V or 24V (Amplifier is supplied with 12V in small size products and 24V in large size products). If you cannot detect power, power supply should be checked against problems.

If the amplifier is being supplied with power, Leg 19 should be checked for 3.3V DC voltage. We should suspect about main integrated circuit if there is no 3.3V. This voltage drops down to 0V and ensures switching the amplifier off in Stand-By mode (AMP_STB signal and main integrated circuit performs the control).

Sound amplifier has I2C communication lines to communicate with the main integrated circuit. Roughly, the voltage level should be below 3.3V and variable at the Pins 23 and 24. Here, the fixed 3.3V gets lower when data is being transmitted, and thus, sound amplifier and main integrated circuit communicate. If this value is constantly 0V, short circuit possibility should be checked where I2C line is connected. Current version of the software should be installed against software problems.

Pin 25 is the reset pin of the sound amplifier. This pin should be high (3.3V) during the time when TV is on. This value might be measured from C544 condenser. If this value is low (0V), RESET_OUT signal should be checked. If this signal, which can be checked from R539 resistance, is low, you may suspect that the problem rests in software or main integrated circuit. If all these inspections don't give any results, you may suspect that amplifier integrated circuit has failure.

Updating TV Software By Using USB Memory
To update TV software by means of USB memory, we will use Target folder available in the system according to product code. Firstly, copy Target folder to USB main directory. Before starting installation, you should check script and panel files in the Target folder which will be installed.

Panel and panel_4k folders contain panel software. You may control panel code from the file in these folders. Mboot contains boot software and the next step explains how to install boot code. Ursa folder is only included in 100Hz panels and contains 100 Hz software.

There are not any critical control elements for other folders.

Shut down TV before inserting USB to TV for software update. (Disconnect the power)

Then, insert USB to TV; press any key of the keypad on TV and plug the TV.

Hold down any key of the keypad on TV until you see that code installation has started.

USB update logo will be shown on the screen during software download from USB.

If code installation has been successfully completed, TV will automatically turn on. Shut down TV to remove the USB.
