panel migth be bad, connection/connector on it might have loosen up already! it it has a warranty then return it at once and ask for a new one! its what you've paid for.

if the band is horizontal your tv has bad y-buffer board. Usually there are 2 buffer boards- top and bottom. if the problem is in the top half of the screen replace the top board, otherwise replace bottom board.
but better to replace both a the same time.

if the tv has a vertical lines from top to bottom it may have bad plasma panel and can be considered as not economical to repair.

Hello,

IF YOU HAVE A SOLID BLACK LINE RUNNING VERTICALLY THEN YOU HAVE A FAULTY MATRIX INVERTER. IF CENTRAL THE MAIN VERTICAL INVERTER NEEDS CHANGED. LEFT = LEFT VERTICAL INVERTER RIGHT=RIGHT.........

ANOTHER WAY TO GET THIS FAULT IS WORN OR DAMAGED RIBBON/PLASTIC GOING FROM THE SCREEN MATRIX TO THE INVERTER

Hope this help......

Y sus board issues

It sounds like an Intergrated Circuit (IC) has fried. Even on a good day, this is not something you can attack at home. As a tech (and as an owner of that model samsung), I'd need a map & tools to know what's going on. Your best bet in this situation is to contact Samsung and let them recommend an authorized service center in your area. Sorry I can't be of more help, but this is a rather serious problem.

if you can open ur tv with out damaging anything your rebon cable needs to be reseated in its connecter which mean unplug it and plug it back in carfully.

these plasma vertical black lines are notorious. there's a video of a fix on this plasma tv repair site. good luck!

It may due to the Logic board, or Logic Scan board, or the Panel failure.

If this is a new set, return it for exchange. This is a warranty repair item.
