Customer Question

I have a Panasonic TH 42PX20 TV. When I push the power button on, the red light stays on for about 10 seconds, and the screen will show a picture. Then, the power light starts flashing and the picture disappears. Do you have solution for this?

I do not use just-answers phone call facility its not beneficial to this kind of troubleshooting.

Thx

If you can use small tools like screwdrivers you will be OK
You need to get the back off the set, locate the mainboard thats the one with all the AV connectors on, unplug and unscrew the board from the chassis, remove the board ,carefully examine the board for its part number usually found on a sticky label on the board or etched on the board, (you may need to go through a few codes before you find the right number)when you get the partnumber try www.shopjimmy.com first, if they dont have it google the partnumber to locate a supplier, its the reverse to fit plug in and switch on TV (plug and play)
Let me know if you need more info
