Panasonic 52 inch TV turns on and turns off after 2 minutes

I had a 50 inch projection tv and when the bulb would go out there was always a popping sound. I went on ebay and found a new bulb at half the price the tv maker wanted. I would replace the bulb. If that is not the problem then you will just have a spare that will be needed at some point.

Power supply or related to it.

Have you even replaced the bulb / lamp on this TV - other than the green light - did they turn solid red / orange at any point? My initial thought is you need to replace the bulb.

my tv wont turn on at all and it worked fine this morning can anyone help its a rca floor model 52 inch

Time to get a new TV. I have similar problem. In my case, the set turns off, LED blinking green for about a minute or 2, then the set will turn on by itself. Something the LED started to blink yellow after blinking green and then shuts off. I can turn it back on. This happens 3 or 4 times in an hour. After that, the TV stays on for as many hours as I want until I shut it off.
And then the problem repeats everytime I turn it on from a cold start.
I have my eyes on the 50 inch Plasma from Panasonic. Bestbuy has one for 999.99.

We originally had a red stripe roughly 3" wide running vertically on the ride edge area of our Panasonic 52" Viera plasma tv. It has now been joined by a solid black stripe of the same width running from the top to the bottom. Living in Germany and purchased at local PX long enough ago that the warranty is likely expired. Now what?

try turning off the auto shut off feature in you set up screens . you can find them through the menu button on your remote. scroll through till you find it and turn it off.
