I have a Toshiba 53" TV rear projection, yesterday the screen went black and sometimes the sound was there but other times it wasn't. If I turn the TV off for a while then turn it on I can see a picture but then it starts going black then back to picture if left on long enough it will eventually go completely black. The model number escapes me right now but I can provide it if it is needed, I also have a short video taken with my phone that shows what it is doing if this would help (the video is poor though). Any help would be greatly appreciated I don't know how long I can stand to watch...
