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.
• 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.

Alternative 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.
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:

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).
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
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.
