Sure this must be obvious for most people here, but I have learn the hard way that it is very important. My new TV (Samsung 32" HDTV) showed 2 symetrical, vertical lighter bar, about 2inch tick. Those bars weren't obvious all the time. I first thought it was source bound. Last weekend, I rent The Score on dvd, and I saw those bars about half the movie time. It was driving me crazy. I was ready to return the set, even if I had to cary it on my back . Then I calm down. I though it might come from the receiver. I then plugeed the tv s-video cable directly in the dvd player. No more bar, yeah!! It points out to the receiver . But when I plugged the cable back in the receiver, the bars were still gone. During the whole process, I cleared the cable mess back there and run the svideo away from power line. So, I think it was some interference, induction or something like that. Does anybody had similar problem? I found very strange that interferances show up on the screen as symetrical bars. Could it be something else?
