PHILIPS 40PFT6709 - CHASSIS TPM14.2A SERVICE MODE, OPTIONS SETTINGS, SERVICE ALIGNMENTS, DIAGNOSING ERROR CODES, LED BLINKING CODES AND MORE OTHER

TPM14.2A Chassis

 

Always respect voltages. While some may not be dangerous in themselves, they can cause unexpected reactions that are best avoided. Before reaching into a powered TV set, it is best to test the high voltage insulation.
It is easy to do, and is a good service precaution.

The TPM14.2A LA is a new chassis launched in Asia in 2014.
The whole range is covered by SCALER MT5591.
The major deltas versus its predecessor DVB-TC; DVB-TC/T2,
with also multi-media, 3D, Ambilight, WIFI, Smart TV, Light Sensor functionality.
The TPM14.2A LA chassis comes with the following styling:
• series xxPFT6700
• series xxPFT6900
• series xxPUT8500
• series xxPUT8600

Key components of this chassis are:
• SCALER MT5591IVDJ HSBGA-758 TV Processor
• TUNER EUROPE SUT-RE231ZN (DVB-T/C, T2 analogue)
• DEMODULATOR CXD2837ER-T4 VQFN-48
• STA381BWTR 20W VQFN-48 for AUDIO Amplifier
• THGBM5G5A1JBAIR 4GB P-VFBGA153 for EMMC IC

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.
For the third digit, the numbers 1...9 and the characters A...Z can be used, so in total: 9 plus 26= 35 different B.O.M.s can be indicated by the third digit of the serial number.

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. 

Board Level Repair (BLR) or Component Level Repair (CLR)
If a board is defective, consult your repair procedure to decide if the board has to be exchanged or if it should be repaired on component level.
If your repair procedure says the board should be exchanged completely, do not solder on the defective board. Otherwise, it cannot be returned to the O.E.M. supplier for back charging

Service Mode.  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.

Software Identification, Version, and Cluster
The software ID, version, and cluster will be shown in the main menu display of SAM and CSM.
The screen will show: “AAAAB-X.YYY”, where:
• AAAA is the chassis name: QN142A x.yy.
• B is the region indication: E = Europe, A = AP/China, U = NAFTA, L = LATAM.
• X is the main version number: this is updated with a major change of specification (incompatible with the previous software version). Numbering will go from 1 - 99 and AA - ZZ.
- If the main version number changes, the new version number is written in the NVM.
- If the main version number changes, the default settings are loaded.
• YYY is the sub version number: this is updated with a minor change (backwards compatible with the previous versions). Numbering will go from 000 - 999.
- If the sub version number changes, the new version number is written in the NVM.
- If the NVM is refreshed, the software identification, version, and cluster will also be written to NVM.

Display Option Code Selection
When after an SSB or display exchange, the display option code is not set properly, it will result in a TV with “no display”.
Therefore, it is required to set this display option code after such a repair.
To do so, press the following key sequence on a standard RC transmitter: “062598” directly followed by MENU and “xxx”, where “xxx” is a 3 digit decimal value of the panel type.  When the value is accepted and stored in NVM, the set will switch to Stand-by,
to indicate that the process has been completed.
During this algorithm, the NVM-content must be filtered, because several items in the NVM are TV-related and not SSB related (e.g. Model and Prod. S/N). Therefore, “Model” and “Prod. S/N” data is changed into “See Type Plate”. In case a call centre or consumer reads in CSM 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).
• Press the following key sequence on the remote control transmitter: “062596” directly followed by the “Home/Menu” button to switch to SDM (do not allow the display to time out between entries while keying the sequence).
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.

How to Activate the Factory mode
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, the following items are displayed,

How to Exit the Factory mode
Use one of the following methods:
• 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.

SAM mode and Factory mode overview

How to Copy NVM Data to/from USB

When copying data to and from a USB memory stick, the folder “repair” is used. When inserting an empty USB memory stick, and downloading data to the stick, the TV will create this folder.
When sending data from a USB memory stick to a TV, the intended data must be available in the “repair” folder.
Note that when copying EDID data to the TV, all necessary EDID files must be in this folder.
Service mode overview for your reference.

Error Codes
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 or via ComPair).
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 three 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
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
The error code buffer is cleared in the following cases:
• By using the CLEAR command in the SAM menu
• By using the CLEAR command in the Factory mode:
• By using the following key sequence on the remote control transmitter: “062599” directly followed by the OK button.
• If the contents of the error buffer have not changed for 50 hours, the error buffer resets automatically.
Note: If you exit SAM by disconnecting the mains from the television set, the error buffer is not reset.

The Blinking LED Procedure
The software is capable of identifying different kinds of errors.
Because it is possible that more than one error can occur over time, an error buffer is available, which is capable of storing the last five errors that occurred. This is useful if the OSD is not working properly.
Errors can also be displayed by the blinking LED procedure.
The method is to repeatedly let the front LED pulse with as many pulses as the error code number, followed by a period of 1.5 seconds in which the LED is “off”. Then this sequence is repeated.
Example (1): error code 4 will result in four times the sequence LED “on” for 0.25 seconds / LED “off” for 0.25 seconds. After this sequence, the LED will be “off” for 1.5 seconds. Any RC command terminates the sequence. Error code LED blinking is in red color.
Example (2): the content of the error buffer is “12 9 6 0 0” After entering SDM, the following occurs.
• 1 long blink of 5 seconds to start the sequence.
• 12 short blinks followed by a pause of 1.5 seconds.
• 9 short blinks followed by a pause of 1.5 seconds.
• 6 short blinks followed by a pause of 1.5 seconds.
• 1 long blink of 1.5 seconds to finish the sequence.
• The sequence starts again with 12 short blinks.

RGB Alignment
Before alignment, set the picture as follows:

White Tone Alignment:
• Activate SAM.
• Select “RGB Align.” and choose a color temperature.
• Use a 100% white screen as input signal and set the following values:
– “Red BL Offset” and “Green BL Offset” to “7” (if present).
– All “White point” values initial to “128”.

In case you have a colour analyser:
• Measure with a calibrated (phosphor- independent) color analyser (e.g. Minolta CA-210) in the centre of the screen.
Consequently, the measurement needs to be done in a dark environment.
• Adjust the correct x, y coordinates (while holding one of the White point registers R, G or B on max. value) by means of decreasing the value of one or two other white points to the correct x, y coordinates (see Table below) tolerance: dx: ± 0.003, dy: ± 0.003.
• Repeat this step for the other colour Temperatures that need to be aligned.
• When finished return to the SAM root menu and press STANDBY on the RC to store the aligned values to the NVM.  If you do not have a colour analyser, you can use the default values. This is the next best solution. The default values are average values coming from production (statistics).

Display Adjustment
You can use the default values. The default values are average values coming from production.
• Enter SAM mode.
• Select a colour temperature (e.g. COOL, NORMAL, or WARM).
• Set the RED, GREEN and BLUE default values according to the values.
• When finished press OK on the RC, then press STORE to store the aligned values to the NVM.
• Restore the initial picture settings after the alignments

Option Settings
The microprocessor communicates with a large number of I2C ICs in the set. To ensure good communication and to make digital diagnosis possible, the microprocessor has to know which ICs to address. The presence / absence of these NT72567 ICs is made known by the option codes.
Notes:
• After changing the option(s), save them by pressing the OK button on the RC before the cursor is moved to the left, select STORE and press OK on the RC.
• The new option setting is only active after the TV is switched “off” / “stand-by” and “on” again with the mains switch (the NVM is then read again).

Reset of Repaired SSB
A very important issue towards a repaired SSB from a Service repair shop (SSB repair on component level) implies the reset of the NVM on the SSB.
A repaired SSB in Service should get the service Set type “00PF0000000000” and Production code “00000000000000”.
Also the virgin bit is to be set. To set all this, you can use the ComPair tool or use the “NVM editor” and “Dealer options” items in SAM (do not forget to “store”).
After a repaired SSB has been mounted in the set (set repair on board level), the type number (CTN) and production code of the TV has to be set according to the type plate of the set. For this, you can use the NVM editor in SAM. The loading of the CTN and production code can also be done via ComPair
(Model number programming).
In case of a display replacement, reset the “Operation hours display” to “0”, or to the operation hours of the replacement display.
Remark:
- After the NVM has been replaced, go to SAM and scroll to the <Reload MAC address>
- Select the item and press <OK> on the RC.

Reset of Repaired SSB
After NVM replacement, reload MAC address via SAM menu. This ensures the correct MAC address to be available in CSM for future repair actions.
Way of working:
• After the NVM has been replaced, go to SAM and scroll to the <Reload MAC address> .
• Select the item and press <OK> on the RC.
Notes:
• Only applicable to all related models that are “Smart TV level 0”enabled (only YouTube access). For models without internet connection feature, no action is needed.
• HDCP keys are located in the NVM. If you are loading NVM with the ComPair tool, there is warning message displayed.
New NVM EEPROMs are shipped with pre-loaded HDCP keys.
SSB Identification
SSB’s of this chassis are identified by a “715” code on the SSB.
715Axxxx-Nnn-MMM-OOOO
• 715 main category, Printed Wiring Board
• Axxxx sub category, sequential coding number
• Nnn Version code
• N Development number
• nn Production number
• MMM Mounting variation code
• OOOO Optional variation code
Make sure when replacing an SSB the SSB identification codes match the replacement panel.

All tests and measurements mentioned hereafter have to be carried out at a normal mains voltage (100 ~ 240 VAC)
All tests and measurements mentioned hereafter have to be carried out at a normal mains voltage (100 ~ 240 VAC)

All voltages have to be measured with respect to ground, unless otherwise stated All final tests have to be done on a complete set including LCD panel in a room with temperature of 25+/-7°C

The Picture Performance assessment such as White Balance (luminance and colour temperature) has to be performed into subdued lighted room after at least 60min of warm-up in order to avoid any temperature drift influence (colorimetry vs time).

Pre-Conditions and Power Supply Check
Before power-on, please check the board according to the relevant block diagram and circuit diagram, make sure that no serious issue or mistake can destroy the board. For example, the output of DC/DC and LDO should not be shorted to ground.
Supply a suited voltage and power-on, then check the voltage according to the relevant block diagram, circuit diagram and voltage spec, the error should be less than 5%, for example, the voltage for main chip (+3V3, +2.5V, VDDC1V15, 1V5_DDR, etc.), the voltage for TUNER (TU_3V3), the voltage for amplifier (AMP_VCC), etc.

Project ID Modification
There are different ID stored in the EMMC depending on different Panels settings and Model features, but there’s only one key branching Project ID able to ensure normal display. And when you power on the TV set, you should make sure the Project ID is accord with the BOM description. If not, you need to modify the ID. There are two methods to modify the ID:

Change Project ID in Design Menu
In case of “Design mode hotkey” is enabled, press “Back” button to enter Design Menu. To modify Project ID, you need to go through “Service menuàProject ID”, then press Left or Right key to select suitable ID (Project name is dynamically refreshed). Finally restart the TV set.

Here below is none exhaustive ProjectID table for reference:

Function Test
Once the Project ID is correct and the TV display normally, plug all external generator devices to relevant inputs/outputs below according to their respective test patterns format and check picture content and sound quality accordingly:

LAN/WLAN Test: MAC Address Upgrade
Upgrading MAC address needs to use the tool in factory and through serial command. The specific method is according to the operation of the factory guidance.

DeviceID (DID) and UserID (UID)
Purpose is to allow Other Network Download (OND) and further specific services over dedicated portal based on AP. For such, specific DID (32 bytes) and UID (8 bytes) needs to be paired and overwritten into memory for internal client encryption, as below:

Those DID/UID codes can only be set using UART commands following enclosed SIACP requirements (rev. v3.9).

LAN Test
A rough LAN test can be done by connecting Ethernet to TV’s RJ45 and check that IP, subnet mask, DNS addresses, which are visible on “HomeàSettingsàNetworkàEthernet settingsàIP settings” (ensure that “Internet Connection” is Enabled at first). More in-depth test can be performed faster using suitable UART/IR commands following SIACP requirements. SW will internally manage Network ID (NID) flag controlling all MAC/DID/UID integrity to facilitate PA screening further.

SHOP INIT (Intilization)
At final process stage, it’s necessary to perform Shop init before any packing to leave Factory mode and restore User default presets according to the requirement of order.
This function is accessible by selecting “Factory Menu à Shop”, then pressing RCU “Right ”or” Left” key.  Other faster methods are available on above enclosed SIACP requirements (rev. v3.9).

Warm-up Test
Following TCL standard and practices, it’s required minimum 15min of Warm-Up that can be considered as Burn-In. Additional aging for White Balance alignment is no more necessary due to consistent picture performance with cloning usage. This function is accessible by selecting “Factory menu à Warm up”, pressing RCU “Right” or ”Left” key to set it ON, and then it enter in Warm up mode. Press “Menu” key on keyboard to exit the burning mode. Other faster methods are available on above enclosed SIACP requirements (rev. v3.9)
