Hi, I recently bought a 30 inch widescreen samsung that's hdtv ready, um model txn3075whf and I also own a samsung dvd player/speaker combo. I use these RCA component cables and have P.scan on, but today when I turned on my T.V. w/out the dvd player on I noticed these wavy green lines running through my screen. I figured they were from interference so moved the cables around a bit but still no luck. After some time they go away, but now I noticed 2 sets of stationary wavy lines that are symmetrical about the middle of the tv, like the shape of a butterfly. These wavy lines seem like thick lines you'd see on sites that try to show interlacing. Now if I watch any dvd scenes with a more solid scene I notice those lines. I tried unplugging my dvd player to see if it was causing this but they're still there. Anyone have any idea on whether this is just poor tv quality or if I happen to have a problem with mine. Another thing i've noticed which irritates my eyes are image burns on this tv, anyone own a tube samsung with the same problem or do i have bad settings? Any opinion is helpful, thanks ahead.
