We bought the Panny about 14 months ago. It has been beautiful until about 1 month ago. It would occasionally fail to come on when either the remote or power button were used to "power up". If the unit was unplugged and left off for a few minutes and then plugged in again it would come on OK. This happened several times and then we left for a couple of weeks. When we came back the TV would not power up at all. We called Panasonic and were given the local authorized service providers name & number. They came out and looked the thing over and declared the "main power board" was bad. They ordered a new board and we waited, and we waited, and we waited some more. They never did find a board and we finally cancelled the order. We did learn the part number for the board (ETX2MM704MGL) and I was able to find and purchase it in about 1 hour. Received it last Friday and installed it today (simple unbolt, remove, place and rebolt). This has resulted in absolutely NO improvement.
What have I done wrong? Lets consider the possibilities:
- the power board is not the problem (I have read here that it might be the video board)
- the new power board is also faulty (not likely)
- I am failing to do something after installing the new board that is necessary (if so, please tell me what to do!!!)
- I should stick to my chosen career and leave the technical work to the professionals (who said the power board was bad!!@#*&^%)
Your insight and help is greatly appreciated!!
