I have a panasonic th37phd8uk. The screen occassionally shuts off out of nowhere. I then have to shut off the power button. SOmetimes for 20 minutes, sometimes just for a few seconds. the tv then works for either a few minuts or a few hours. This problem came out of nowhere. When I call panasonic concierge service, they simply tell me it's a service problem. What does that mean. Anybody know what's going on?

Rule out any loose contacts in power outlet, RC Jack, cables and connectors. The problem described by you calls for opening the back cover and further investigation, which should only be done by a qualified service technician.
I don't know but I'm having a similar problem. I have a plasma
TH-50PZ77U. It will run for a while and then shuts off. Also, the volume goes up and up and then it shuts off at times. Like I have a ghost here. I had both of my sat. recievers replaced. It seems to get worse over time with shut down. I called panasonic and they had no info and denied this was an issue but I beg to differ from my research here online. It's only a few years and we paid lots of $$$. They gave me a # for service 1 hour away!
One of the "Y" buffer boards have failed. The buffer boards are located on the left side of the set looking from the back. There are two of them. One for the upper half of the screen, one for the lower. Disconnect and replace the one that had the blank portion of the screen.
I have seen a fault where the Plasma display was giving sparkling green dots, and then the set would shut down after about 10 minutes. After waiting for about 40 minutes, I would re-start and the process would work the same, and then the set would shut down.
I tried freezing the boards one by one with freeze-spray, and heating with a heat gun to see where the thermo fault could be. I had no success.
Fortunately I had access to a scrapper set of the exact same model. After spending many hours with the process if elimination, I worked the fault down to be the screen itself! Unfortunately, with the scrapper set that I had its screen was very weak. Swapping the screens between the two sets proved that the original screen has failed.
I don't want to discourage you. You may be down to the point of what I reached!
