Also, it is possible that same model on the market is produced with

3、 two production centers, however their partslist is the same. In such case, no alternative B.O.M. will be created. By looking at the third digit of the serial number, one can identify which B.O.M. is used for the set he is working with. If the third digit of the serial number contains the number “ 1

4、” (example: KX1B033500001), then the set has been manufactured according to B.O.M. number 1. If the third digit is a “ 2” (example: KX2B0335000001), 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

5、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. LM is Arts), digit 3 refers t

6、o 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 2008 week 50). The 6 last digits contain the serial number. Figure 2-1 Serial number (example) 2.3.6Module Level Repa

If your repair procedure says the board should be exchanged completely, do not solder on the defective board. Oth

While some sources are expected to have a possible dangerous impact, others of quite high potential are of limited current and are sometime

9、s held in less regard. 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. 2.4Abbr
