What are these blue bars on my HDTV ?
Recently, my 32 inch Sharp HDTV has two vertical blue bars (about 1 1/2 wide)that appear on the screen. They are present even when the TV is disconnected from cable or antenna, and also when DVD or games are used. The TV is one month out of warranty. I am hoping that it is some kind of interference and not the set, but that may wishful thinking. Any ideas what may be the cause? Thanks!
