Any place to buy the cheap YSUS replacement board for Plasma TV?

[lovecd]

My current 720P plasma TV from Zenith/LG got some problems, won't show pictures, kind of dard screen or funny images. Audio and tuner are all working fine. So I guess the y-sus board needs to be replaced. Considering this is a used 720P TV, I will probably won't change it if the price for Y-SUS is over $100. Can any one give some advise where I can find the relatively cheap Y-SUS board? I don't mind if it is a used one, as long as it is working.

Thank you!

What is the EAX/EBR/ or similar part number on the board? And model of the TV? Sure it is Y-sus?
More likely to be Z-sus.
Picture of fault?

TV is Zenith Z50PX2D 50-Inch Plasma. By the way, how to check the EAX/EBR number?
I will try to take some pictures and post them here.

Many thanks!

Here are some pictures I took. Any ideas it is Y-sus or Z-sus?

Have you verified that you're getting the proper panel voltage outputs from the power supply (see label on back of panel)?

Assuming if all outputs are correct, what could be the cause of the issue?

Thanks!

I'd look at the Y and Z sustains if you don't find issues with the power supply, but make sure you thoroughly investigate the power supply outputs.

It is looking a lot like a Z-sustain issue to me.

Thank you guys! I will do some checkings and let you know what I found. By the way, do you have any link for tutorial on how to use DMM to check the output voltage and fuse, etc.?

Fuses are tested with power off and meter on ohms across the fuse; readings less than 3.0 ohms are generally good.

Hi All,

After a while, I decided to replace all y drive, y-sus and z-sus boards, got a good deal from ebay. However, after the boards are all replaced, the problem is not resolved. The symtom looks different now. I posted some pictures with the replacement boards installed. Any ideas whatelse could be wrong? Thanks!
