Hello all, I'm hoping someone here can help. I have a 5yr old Samsung that recently one evening developed a Red convergence problem, or what I believe is a red convergence problem. The screen looks a little curved in the center and when I go to the convergence section, the Blue is all lined up but the red is off and I can't manually adjust it. Perfect focus also fails; it simply never makes it through. Now doing some research online, I figured it was a IC Chip that had dailed or something so I ordered some new ones online and desoldered to old ones out and put the new ones in.
