Hello everyone, I am new to the forums and desperate for an answer. I have a 37" LG LCD TV, which looks superb. A week ago, we noticed that sometimes, when we tried to change the channel, suddenly the screen went blank. Just as if it was turned off (no menus, no image, no TV graphics, nothing) but with the sound remaining intact. The only solution seemed to turn it off for 30+ minutes, and turn it on again, but soon it happened again. Yesterday, it began to do it when commercials popped up. It IS strange. Just in case anybody wonders, I use a composite (you know, the single round plug) jack as TV input. I know it's the worst possible option, but it's what I have now. Does anybody have the slightest clue about what could this be about? I phoned LG and they couldn't give me a straight answer. Thanks a lot in advance!
