I have the same problem with my HP PL4260N 42" Plasma HDTV serial # CNH6141988, model # CPTOH-0602. I have perfect sound and can change channels still with sound but NO PICTURE. I am a consumer with a question that need the advise of an expert.

The short answer is a cracked LCD is not worth repairing.

Usually, when you replace Y-sustain board, for older plasma, they suggest to replace both Ydrive board (up and low). And sometimes, Z-sustaint.

Im not sure your are an expertise in this matter so be very careful when you open a TV because hasardous voltages can kill you in the worst escenario.

If you are not, don't work on your TV. It will be your sole responsibility.

Check ships on Y drive board (both board are installed on the right side of Y-sustain. They have square black ships that used to get bad. If they don't have aluminum cooler on them, you can see if they are burned or have holes on them. Old plasmas use to have issues with those boards. Before you installed the Y Sustain you should check Ydrive boards. Maybe you damage the Y Sustain because the Y drives weren't good.

Try to replace the fuse, disconnect the Ydrive from Y Sustain, turn on TV and check for voltages on Y sustain (panel has a sticker with each voltage). Hope you didn't damage Y sustain and can find Ydrive board to fix your TV.

And REMEMBER, you can kill yourself when you work on TVs.

Did you try buying a new HDMI cable? You can also try some of the solutions in the post called "Hp 42 plasma tv cptoh 0602 I get sound but no picture."

Sounds like your panel might be going out or a faulty video card. This is the first time I have heard of a solid pink screen on a plasma. Usually this happens on LCDs, though they sometimes go white and stay white, which does signal a bad panel. tv needs repair

There is some voltages that need adjusted in your tv and possibly the z sustain board needs replaced if the voltage adjustment doesn't fix it.

y sustain board needs adjusting or replacing
