REPAIRING AND NOT THROWING AWAY

Richtige Fernseher haben Röhren!

Richtige Fernseher haben Röhren!

In Brief: On this site you will find pictures and technical information about Service Modes, Circuit Diagrams, Firmware Update procedure, Disassemble procedure, Universal remote control set-up codes, Troubleshooting and more....

If you go into the profession, you will obtain or have access to a variety of tech tips databases HERE IT IS Master Electronics Repair !.

These are an excellent investment where the saying: 'time-is-money' rules. However, to learn, you need to develop a general troubleshooting approach - a logical, methodical, method of narrowing down the problem. A tech tip database might suggest: 'Replace C536' for a particular symptom. This is good advice for a specific problem on one model. However, what you really want to understand is why C536 was the cause and how to pinpoint the culprit in general even if you don't have a service manual or schematic and your tech tip database doesn't have an entry for your sick TV or VCR.

While schematics are nice, you won't always have them or be able to justify the purchase for a one-of repair. Therefore, in many cases, some reverse engineering will be necessary. The time will be well spent since even if you don't see another instance of the same model in your entire lifetime, you will have learned something in the process that can be applied to other equipment problems.
As always, when you get stuck, checking out a tech-tips database may quickly identify your problem and solution.In that case, you can greatly simplify your troubleshooting or at least confirm a diagnosis before ordering parts.

Happy repairing!
Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of. And this will happen sooner, rather than later.

DC offset error description

DC offset detection circuit design
• Purpose:
To prevent breakdown, burning and emitting smoke from customer's car speaker when occur DC offset between speaker output "+" and "-".
• Target:
Detect DC offset, then stop the Power Amp operation and shift to specified condition.

Possible causes of DC offset at speaker output lines
(1) Mis-connection for speaker output for example touch to car body or battery line.
(2) Current leak of coupling capacitor for Power IC input.
(3) Current leak of Ac-GND capacitor for Power IC Ac-GND.
(4) Capacitor shorted of above parts due to foreign object.

To detect DC offset Error
• Mis-connection
- Short any one speaker out line to GND or Vcc
• Capacitor leak
- Parallel 330kΩ to either any one of coupling cap or Ac-GND cap (to simulate current leakage of capacitor)
- Shorted either any one of coupling cap or Ac-GND cap.

Manipulate after detect DC offset
• If detected error 10 consecutive times, and 10th error occurred in "Mis-connect detection period", judge as "Mis-connect".
• If detected error 10 consecutive times, and 10th error occurred in "Capacitor leak detection period", judge as "Capacitor leak ".
• If detected error 10 consecutive times, and 10th error occurred in "Other detection period" and detected another 10 errors consecutively, then judge as "Other".
• If judge as "Mis-connect". - turn off speaker output.

- display "MIS WIRING" > "CHK WIRING" > "THEN RESET" > "UNIT".
- key access disable except button of Eject, Reset and service mode
- record error in EEPROM "DC1 ERR"
- Set is able to be recovered by Reset button.

• If judge as "Capacitor leak ".
- turn off speaker output.
- display "WARNING" > "CHK WIRING" > "THEN RESET" >"UNIT".
- key access disable except button of Eject, Reset and service
mode
- record error in EEPROM "DC2 #" (# means counter number)
- Set can be recovered by pressing the Reset button before the capacitor leak error counter reach "DC2 4".
After that, only clear the counter back to "0" can recover the set.
• If judge as "Other" (manipulation same as mis-connect)

How to cancel DC offset error

Check to be sure the terminals of the speaker leads are covered with insulating tape properly, then reset the unit.
If an error message does not disappear even after a reset, there is a need for internal repair.

HDMI – UHD

(HOME) > Settings > General settings > HDMI Ultra HD

This TV can display Ultra HD signals. Some devices connected with HDMI – do not recognize a TV with Ultra HD and might not work correctly or show distorted picture or sound.

To avoid the malfunctioning of such a device, you can set the signal quality to a level the device can handle. If the device is not using Ultra HD signals, you can switch off Ultra HD for this HDMI connection.

Identification: The bottom line of a type plate gives a 14-digit serial number. Digits 1 and 2 refer to the production centre (e.g. SN is Lysomice, RJ is Kobierzyce), digit 3 refers to the B.O.M. code, digit 4 refers to the Service version change code, digits 5 and 6 refer to the  production year, and digits 7 and 8 refer to production week (in example below it is 2010 week 10 / 2010 week 17). The 6 last digits contain the serial number.



It should be noted that on the European Service website, “Alternative BOM” is referred to as “Design variant”.

The third digit in the serial number (example:

AG2B0335000001) indicates the number of the alternative B.O.M. (Bill Of Materials) that has been used for producing the specific TV set. In general, it is possible that the same TV model on the market is produced with e.g. two different types of displays, coming from two different suppliers. This will then result in sets which have the same CTN (Commercial Type Number; e.g. 28PW9515/12) but which have a different B.O.M. number.

By looking at the third digit of the serial number, one can identify which B.O.M. is used for the TV set he is working with. If the third digit of the serial number contains the number “1” (example: AG1B033500001), then the TV set has been manufactured according to B.O.M. number 1. If the third digit is a “2” (example: AG2B0335000001), then the set has been produced according to B.O.M. no. 2. This is important for ordering the correct spare parts.

Service Modes

The Service Mode feature is split into following parts:

 Service Alignment Mode (SAM).

 Factory Mode.

 Customer Service Mode (CSM).SAM and the Factory mode offer features, which can be used by the Service engineer to repair/align a TV set.

SAM and the Factory mode offer features, which can be used by the Service engineer to repair/align a TV set. Some features are:

Make alignments (e.g. White Tone), reset the error buffer(SAM and Factory Mode).

 Display information (“SAM” indication in upper right corner of screen, error buffer, software version, operating hours, options and option codes, sub menus).

The CSM is a Service Mode that can be enabled by the consumer. The CSM displays diagnosis information, which the customer can forward to the dealer or call centre. In CSM mode, “CSM”, is displayed in the top right corner of the screen. The information provided in CSM and the purpose of CSM is to:

 Increase the home repair hit rate.

 Decrease the number of nuisance calls.

 Solved customers’ problem without home visit.

Note: For the new model range, a new remote control (RC) is used with some renamed buttons. This has an impact on the activation of the Service modes.

For instance the old “MENU” button is now called “HOME” (or is indicated by a “house” icon).

Service Alignment Mode (SAM)

How to Activate SAM

To activate SAM, use one of the following methods:

 Press the following key sequence on the remote control transmitter: “062596”, directly followed by the “INFO/OK” button. Do not allow the display to time out between entries while keying the sequence.

Or via ComPair.

After entering SAM, the following items are displayed, with “SAM” in the upper right corner of the screen to indicate that the television is in Service Alignment Mode.

How to Navigate

 In the SAM menu, select menu items with the UP/DOWN keys on the remote control transmitter. The selected item will be indicated. When not all menu items fit on the screen, use the UP/DOWN keys to display the next/previous menu items.

 With the “LEFT/RIGHT” keys, it is possible to:

– (De) activate the selected menu item.

– (De) activate the selected sub menu.

– Change the value of the selected menu item.

When you press the MENU button once while in top level SAM, the set will switch to the normal user menu (with the SAM mode still active in the background).

How to Store SAM Settings

To store the settings changed in SAM mode (except the RGB Align settings), leave the top level SAM menu by using the POWER button on the remote control transmitter or the television set. The mentioned exceptions must be stored separately via the STORE button.

How to Exit SAM

Use one of the following methods:

 Switch the set to STANDBY by pressing the mains button on the remote control transmitter or the television set.

 Via a standard RC-transmitter, key in “00” sequence.

Note: When the TV is switched “off” by a power interrupt while in SAM, the TV will show up in “normal operation mode” as soon as the power is supplied again. The error buffer will not be cleared.

Remark:

1. Press following Key Combination to reset the “Op Hour”: “Menu/Home” + “101011” on the remote control transmitter.

2. Under main menu “NVM editor”, select “Service Data”, you can use the UP/DOWN keys to view and change the set Type number, the set Production Number or the 18AC of a part.(The NVM-editor still has the same function as before, alpha-numeric entry.)

Factory mode:

 Displaying and or changing Panel ID information.

 Displaying and or changing Tuner ID information.

 Error buffer clearing.

 Various software alignment settings.

 Testpattern displaying.

 Public Broadcasting Service password Reset.

 etc.

To activate the Factory mode, use the following method:

 Press the following key sequence on the remote control transmitter: from the “menu/home” press “1999”, directly followed by the “Back/Return” button. Do not allow the display to time out between entries while keying the sequence.

After entering the Factory mode, we can see many items displayed, use the UP/DOWN keys to display the next/previous menu items.

How to Exit the Factory mode

 Select EXIT_FACTORY from the menu and press the “OK” button.

Note: When the TV is switched “off” by a power interrupt, or normal switch to “stand-by” while in the factory mode, the TV will show up in “normal operation mode” as soon as the power is supplied again. The error buffer will not be cleared.

Customer Service Mode (CSM)

The Customer Service Mode shows error codes and information on the TVs operation settings. The call centre can instruct the customer (by telephone) to enter CSM in order to identify the status of the set. This helps the call centre to diagnose problems and failures in the TV set before making a service call.

The CSM is a read-only mode; therefore, modifications are not possible in this mode.

How to Activate CSM

To activate CSM, press the following key sequence on a standard remote control transmitter: “123654” (do not allow the display to time out between entries while keying the sequence). After entering the Customer Service Mode, the following items are displayed. use the Right/Left keys to display the next/previous menu items.

Note: Activation of the CSM is only possible if there is no (user) menu on the screen.

How to Navigate

By means of the “CURSOR-DOWN/UP” knob (or the scroll wheel) on the RC-transmitter, can be navigated through the menus.

How to Exit CSM

To exit CSM, use one of the following methods.

 Press the MENU/HOME button on the remote control transmitter.

 Press the POWER button on the remote control transmitter.

 Press the POWER button on the television set.

3. Copy the software to USB flash disk (root directory).

4. Switch off the TV and Insert the USB memory stick that contains the software update files in one of the TV’s USB 2.0 port.

Note: It contains USB3.0 port, if connect on it, the software may can’t be detected.

5. Switch on the TV. The TV will detect the USB memory s tick automatically. Then a window jumps out as below:

6. When the TV software is updated, the TV will turn on again automatically. Remove your USB flash drive.

7. We can enter in CSM or Factory mode to check the current software version.

The following update is for .upg file.

Step 1: Ready for F/W Upgrade

1. Rename the file to “autorun.upg”.

2. Prepare a USB memory (File format: FLAT, Size: 1G~8G).

3. Copy the software to USB flash disk (root directory).

4. Switch on the TV and Insert the USB memory stick that contains the software update files in one of the TV’s USB 2.0 port.

Note the version of this F/W before you change the software file name.

Step 2: F/W Upgrade

Press [Quick settings], then Choose [Update Software] in the Settings menu

2. Choose [Local Updates], then press OK.

3. Select the file that you downloaded and press OK.

4. Choose [Update], then choose [Start] on following step.

5. Upgrade in progress.

Step 3: Check the SW version.

After burning software, TV will restart

2. Press “123654”, enter Customer Service Mode to check if the software version is correct.

Caution: Please make sure that software upgrade is finished before unplug the USB and AC power.


Error Code

Error codes are required to indicate failures in the TV set. In principle a unique error code is available for every:

• Activated (SW) protection.

• Failing I2C device.

• General I2C error.

The last five errors, stored in the NVM, are shown in the Service menu’s. This is called the error buffer.

The error code buffer contains all errors detected since the last time the buffer was erased. The buffer is written from left to right. When an error occurs that is not yet in the error code buffer, it is displayed at the left side and all other errors shift one position to the right.

An error will be added to the buffer if this error differs from any error in the buffer. The last found error is displayed on the left.

An error with a designated error code never leads to a deadlock situation. It must always be diagnosable (e.g. error buffer via OSD or blinking LED).

In case a failure identified by an error code automatically results in other error codes (cause and effect), only the error code of the MAIN failure is displayed.

How to Read the Error Buffer.

You can read the error buffer in following ways:

On screen via the SAM/CSM (if you have a picture).

Example:

– ERROR: 000 000 000 000 000: No errors detected

– ERROR: 013 000 000 000 000: Error code 13 is the last and only detected error

– ERROR: 034 013 000 000 000: Error code 13 was detected first and error code 34 is the last detected (newest) error

 Via the blinking LED procedure (when you have no picture).

Error codes overview

In this chassis only “layer 2” error codes are available and point to problems on the SSB. They are triggered by LED blinking when CSM is activated. Only the following layer 2 errors are defined:

How to Clear the Error Buffer.
