I have the same problem. Factory reset did not help (hold Vol-minus on set and menu on remote five seconds, then unplug). Can there be something in service mode that would help?

My panasonic model #TH-50PX75U wont turn on, it powers up but the led light stay on not blinks any time.


Unplug the power cord. Press and hold the power button for 30 seconds, repeat. Plug it back in and try to turn it on.
If this doesn't work, it would be time to call in a repair tech. Is the TV still under warranty? Extended warranty?

Panasonic plasma


If you open the back,look at the can shaped items.If any of them have the tops bulged out,they need to be replaced.This should solve your picture problem,unless there is something else wrong.What is happening,is they are heating up,and the picture goes out.I bet the longer you have the TV off,the longer it stays on?Hope this helps.Thank You very much!
