im not good with tv's and i have a problem. I recently bought the Sony 42' rear projectiomn 3lcd tv KDF-E42A10 and the hd looks great but alot of the other channels look REALLY bad. I think maybe i did something wrong with the video. It looked better in ch3 but the hd ddint work so now i have it in vid5 when the hd looks good but the rest looks terrible. PLease if someone can help me i would appreciate it.
