The edge ribbon connector may not be connecting (on the inside of the tv). Cure is foam strips between screen edge connecters and inside cover. Or, Memory chip (used to make the picture appear), may be bad. All flat panel tv's use a memory chip to make picture appear (it is digital after all). And if memory chips are bad, picture will have lines, jags etc. But it sounds like you have edge connecter problems. Place foam between inside cover and screen. TV may have been thrown around in shipment, and edge connecters came undone. They're very lightly soldered on some sets.
