    I experienced the same problem. While watching television the picture and sound went out. The power light on my 42HP66 plasma will turn on and off, but there is no picture or sound, and the set does not even warm up.

This is weird. I also have a plasma 50" model PS5Q91HDX and on the 5/02/11 the screen went blank when my friends daughter was watching a Wiggles DVD. The image kept coming back, flashing a scene or two before going black again. But the sound is perfect.

I wonder what is going on? Is anyone else having trouble with their 3-4 year old Samsung 50" TVs???
