Question about Samsung HP-R4272 42 in. Plasma HDTV
My picture was fine. When I looked again at the screen, most of the screen had narrow, broken, horizontal stripes from top to bottom, except for a 6" wide horizontal band about 6" from the bottom which showed a clear picture.
There are two convergnece boards in this tv. one is called the convergence (DCU) the other is called the convergence amp board. this amp board has the (STK`S) on it and ids your problem. in most cases we repair this board.
good luck :)
let me know if you need more info?

Its just because of some faulty input cables or shorttracking on internal board.

There is 60% of chance you will need a new screen. The problem you may have is dead driver (part of a screen) or poor connection between plasma glass and rubber wire connector. There is some solution for it but not for long time. PDP panel and address driver on it not separated. If one of 26-40 drivers is going out, you need new screen. It is a real question why manufacturers don't separate expensive PDP panel and $40 driver on it. It is easier to replace small $40 part than the entire screen. So far they just ignore this issue.
