Philips 50PUN8215, 55PUN8215, 65PUN8215, 70PUN8215 LED TV-How to enter service mode, Error codes, Power board schematics, Firmware update and more

 

Philips 50PUN8215, 55PUN8215, 65PUN8215, 70PUN8215 LED TV- platform MTK5599 – chassis TPM20.1KLA – How to enter service mode, Error codes, Power board schematics, Firmware update and more

Operating System: Android OS : Android Pie 9

126 cm - 50 inch

• 139 cm - 55 inch

• 164 cm - 65 inch

• 178 cm - 70 inch

• 189 cm - 75 inch

• LNB : DiSEqC 1.0, 1 to 4 LNBs supported, Polarity selection 13/18V, Band selection 22kHz, Tone burst mode, LNB current 300mA max.

• DVB-S/S2 QPSK, symbol rate 2 to 45M symbols, SCPC and MCPC.

Sound Output power (RMS): 20W

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.

• All ICs and many other semiconductors are susceptible to electrostatic discharges (ESD ). Careless handling during repair can reduce life drastically. Make sure that, during repair, you are connected with the same potential as the mass of the set by a wristband with resistance.  Keep components and tools also at this same potential.

• Be careful during measurements in the high voltage section.

• Never replace modules or other components while the unit is switched “on”.

• When you align the set, use plastic rather than metal tools. This will prevent any short circuits and the danger of a circuit becoming unstable.

BOM identification

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.

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.

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.

Firmware upgrade

Press [Settings] > [update software], then Choose [Search for update] in the Settings menu.

2. Choose [USB], and then press OK.

3. Choose [Identify], and then press OK.

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

5. Identify the software and choose [Done], then choose [Start] on following step.

6. Choose [Update] press OK start the software update.

6. Upgrade in progress.

Step 3: Check the SW version.

1. After burning software, TV will restart

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

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

• 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).

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.

Set Option Code

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: see column “Set Option Code” in below tab. After resetting the Display Code, restart the set immediately.
