Hey there. I have a 43" Samsung Plasma (PS43D450A2) that started out with a single horizontal black line of 1-pixel height. It appeard about 8" from the top of the screen.
Gradually, they kept increasing. Some joined to form a thickened line. I'd say I have about 20 such annoying lines.
What could be the problem? Is it something I can fix myself?
Thanks a ton.
