Hi! I was watching my TV - Samsung LN-S4092D - and the picture went to black with a few very light horizontal lines for about 30secs. After that it went to complete black. I thought it might just be that channel. I changed channels and the same thing. I tried to switch Tv source for my DVD box. I tried a DVD and it did not show. In fact, when going through the video sources, I got no text showing that it was going through the different sources. I had volume going throug my cable box so I turned that off and I found that TV also had no sound. I checked other TVs in the houe and they are all working fine. Please advise! Thanks, Bob Garcia
