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.
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.

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).
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
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.
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.
