I have a Pioneer Elite 510 and I have a problem that I was going to post about. My TV shuts down automatically and make a chirping sound and will not turn back on. You have to unplug it and wait a few minutes to plug it back in. This has been happening for about 8 months but it went away and now it has come back and is even worse. Now I can not get it to come back on at all? Anybody experience anything like this? Help please.......
