Screen works perfectly for few minutes then becomes garbled.
The screen works perfectly, then suddenly today after 3 or 4 minutes there are garbled random lines, which stays like this, or else goes black. The sound is usually still working. If i disconnect the power , then switch back on, the picture is ok again for a while. Any ideas?
The TV is a 2010 46” Panasonic viera plasma ( TX-P46GW20 ) No problems until today.
Below is a video of the problem..
I managed to get the back off the TV. Everything looks in good shape. No ribbons are disconnected, capacitors look ok to the naked eye. Not too much dust and dirt.

Thanks Matt. I will definitely try this. But because the problem is recurring each time after a few minutes, i was thinking maybe it’s to do with some kind of overheating or capacitor issue. I’f its something simple i’d rather not have to buy a new TV!
Thanks for your suggestion!

On a plasma TV capacitors are used for things related to power supply, audio and rf signals not really display. I would think overheating would cause it to turn off completely. However a thorough cleaning could remedy any heat issues.
