    Same issue with my HP picture but sound. I've seen a couple of post that say to replace they Y-SUS board only and other posts that state that you'll need to replace (2) boards. Does replacing the Y-SUS board (TNPA3243AB-PA) only fix the problem?

    Same problem. Power on, sound, but no picture - just a black screen. I called HP and they told me it was the Y-SUS board. And for only $620.00 they'd get someone tyo come out and fix it. Which, of course makes the product a disposable TV - because to buy a new, presumably better TV is about 800. The TV is 2.5 years old. It is ridiculous.

    Does anyone have the schematics to change this Y-SUS board? My TV is still mounted on the wall but it can pull out a little. Can the board be changed without dragging the thing off the wall?

The problem is the "Y-SUS" board located inside the set on the left hand side under the left vertcal brace. It has a large aluminum heat sink on it. The part can be ordered from Union Electronics at:

Look up part number: TNPA3243AB-PA It lists for about $115 plus s/h
