I've had a Vizio 32" flat screen HDTV for about 2 years and the screen suddenly turned black today while I was watching something I DVR'd. I never lost audio and it has been working fine with not one problem before this. I unplugged it and plugged it back in - same problem. I took the smaller TV from my bedroom and hooked it up to my cable box & it's working fine, including DVR playback so it's not that - Not sure what to do - I think I bought it from Sears but I'm sure the warranty was only one year. Any ideas on what else I can check before I chuck it and buy a new one?
