    I hear this is the Y sustain board and have found it rebuilt for $60..00 . ALl depends on how electronically savvy u are if u can replace urself. I just came here to get the repair manual and will attempt to do myself this weekend. Hopefully its worth it.

I have a HP PL4260N that works fine except for a whiteish hazy patch that will show up on the screen in various spots at times. Also when I have a picture up that is mostly white, like this web page, I can...

The buzzing is normal thing, because white screen requires most power and your chopper works at its max. The sound comes from inductance coils and transformer because of old isolation and glue which shouldnt make any problems.

You most certainly do not want to disassemble the tv. HP has made a valid diagnosis, you would be best off taking the replacement board and tv to a repair shop and have them change it for you. Yeah, it may cost a little, but Plasma TVs have very fragile displays- very easily broken.
