Re: Panasonic TX-P42GW20 display flickering after some time
Unfortunately pressing on different parts on the mainboard did not have any effect on the display problem.

Re: Panasonic TX-P42GW20 display flickering after some time
The heatsink came off pretty easily. Removing the board from the TV was not neccessary. [url]https://i.imgur.com/JDxmtkV.jpg[/url]
But the display problem remained the same. I can also hear a buzzing noise. I think it's coming from the power board. But that should be normal, right?Re: Panasonic TX-P42GW20 display fli...ut the displayLeave a comment:

Re: Panasonic TX-P42GW20 display flickering after some time
Yes it does. Takes about 1-2 minutes until the problem occurs. I also immediately turned off/on the TV and went straight into service mode to check if it still shows OK for all values. It does, but shortly after the problem occurs again.Leave a comment:

I put the TV back to factory settings and made a screenshot of the service menu afterwards [url]https://i.imgur.com/LyzUYUF.jpg[/url]
Pressing the heatsink while the TV is having the display problem did not produce any visible change.Re: Panasonic TX-P42GW20 display fli...ng the displayLeave a comment:

Hey Moreno, thank you for your reply.
The TV is still disassembled and I can see all the boards as show in the imgur album ([url]https://imgur.com/a/UWhAO[/url]).
The mainboard is the on in the center? ([url]https://i.imgur.com/Dl6Fpqp.jpg[/url])

The screen flickering will also occur if no video source is connected. Sound is working fine. Anything else I could test?Leave a comment:

Panasonic TX-P42GW20 display flickering after some time
The TV turns on and works fine. After about five minutes the display starts flickering. Where do I start to look for the source of the problem?
