Purchased three weeks ago with Onkyo receiver. No matter how the TV gets a signal (direct from HD cable box; cable via receiver; DVD via receiver), we get green (mostly) and purple horizontal lines scrolling up the screen in a set pattern, ghost-like. We have replaced everything -- TV, cable box, receiver -- and the problem persists. Samsung tech support was NO help. CC sales suggested grounding problem so we installed a grounding adapter; didn't help. (Should note we rewired the entire house only four years ago.) Short of returning everything -- and coming home with nothing -- are there any ideas? Thanks!
Something I meant to add to the original post: I saw someone ask this same question in August 2006 (Samsung DLP + Onkyo receiver) but did not see any response. Can someone direct me to a different thread?
