Pioneer 1150HD: Bad panel? Or the Sus-board? **PIC

[TechShui]

What do you guys think?

I have a bad feeling that the panel is slowly dying and that's obviously not replaceable.

But if I'm lucky, could it be just one of the Y/Z Sustain boards?

The black line? That's a failed X-buffer and yes, it could be the panel, but not always.

Thanks for the reply tom66,

What have I got to lose, I think I'll put in a new buffer and see what happens!

The weird thing is this TV doesn't appear to have buffers... at least by that name, there IS a part labeled X drive SUB. I'm I correct in assuming the buffer and the SUB are one and the same?

There's also a whole Drive Assy. on Shopjimmy, which is basically the X mainboard + X Drv SUB. (but why spend more than I need to?)

Yeah, some (most) manufacturers put the buffers on the panel itself, if the buffer drive IC goes the panel is toast. Others put the drive chips on the driver boards so you can sometimes get lucky.

I understand completely now. I've only done a few plasma's and up until this point I'd only seen buffer/scan boards that were separate.

I think this Assembly has the buffer chips soldered on:

I say this, because there's epoxy on some components all neatly in a row, and that reminds me of a long buffer, but I could be wrong.

That's the same assy. I was referring to earlier, I was mistaken in assuming it was two parts, once I zoom in, I see it's all one PCB.

Thank you again for clearing things up.

That's the Y-drive (row buffer); not the X-drive (column buffer.) Most Y-buffers are replaceable, not all X-buffers are.
