Hi guys I have a Panasonic TX-P42S31B a few weeks ago we noticed it buzzing on light screens which it had never done before it was brought December 2011 new I came home tonight switched it on got two clicks the green led flashed 10 times then another click and nothing it had switched off I wouldn't mind if it got a lot of use but it gets used about two hours a day!! Any help would be appreciated many thanks justin
Thanks guys I have checked again this morning and tried to count the led blinks I think it's actually 7 they blink really fast. I don't want to go and buy another TV if its an easy fix but it has put me off panasonic
7 blinks is SC, SU or SD. Very common with this model. NOT power supply, which would be none (no power), 2, 4 or 10 blinks.
You need to take the cover off and tell us the part #s of the boards, take pictures if you are not sure.
The buzzing is caused by the loose/dirty/bad screws, what I have heard though is that eventually if unchecked it can damage the board.
