I do not have a manual, but HP just replaced my Y Sustain board on my PL4260N (Model (ED429AA).
HP replaced it free because of a known problem with something they call "Plasma Mal-Discharge'.
The part number on the work order is 1032298-HS.

This did not fix my pixilation lines across the top.
I have been told that my Y-DRV is probably bad, but I need to pay for that replacement.
But, they did not verify that it is bad and did not guarantee this is what is wrong.

The y sustain board is bad

Good day!!!

If you think the Y-sustain board on your plasma is bad..

you can replace it on your own...

Y-sus is a hand insert board. There is no soldering required.

Follow this steps:

1. Just remove speakers and stand.
2. Then take out screws holding down back panel.
3. You may need to remove supports inside, just remember what order you do so. take out old y sus and put it new one. simple.

I hope this information will be helpful...

Thanks for using fixya...

You probably have a defective Y-Sustain module and possibly upper and lower drive boards. Best to have a service company evaluate it first.

No video but audio is fine on Sanyo 42" DP42746 TV

If you unplugged the Ysus board, then you need to replace the Ysus board, or both sustain boards. This is the part: The part is often available on Ebay, or from manufacturer. Look also at Vance baldwin or Partstore. To do a good job the Sustain boards should be tested by a tech , following service manual. It is almost for sure sustain board by the way.

Looks like we all got took by HP

It's called the Y Sustain Board and HP never made a plasma board in there life, someone else did, so, look on the board for any kind of numbers and go from there. There's only a handfull of comp's that make all the boards out there today and yesterday. If you have no luck, let me know!
