Hp model# cptoh-0603 picture turned black, still have sound

SOURCE: Problem with picture on HP Plasma TV

hello!
This is known problem with PDP displays. That means: one of X-buffers has bad connection to the PDP(plasma display). Or, in some cases, depend on PDP type, it could be panel itself at fault. You need to open your set carefully and get an access to X-buffers. Usually, at the very bottom of PDP, covered with aluminum heat sinks. By turning set on, while face down, start tapping slightly with isolated handle of medium size screwdriver. Observe, when line(s) vanished. That's where connection(ribbon cable) between PDP and X-buffer is compromised.
In some PDPs, those integrated into panel itself and nothing you can do, except to live with that or replace panel. Hope, you end up just reconnecting ribbons. Anyway, you must have very good technician background to do so.
good luck,
Alex.

I had the same problem today, Hp wanted $629+tax to fix. With a little mechanical ablity anyone can fix this.
1. remove back covers
2. left-hand side is the video board
3. two white fuses
