Ok, my bad, must have misread your thoughts. Some other forum member may have further thoughts on how to test Y-Drive boards, or there are a few youtube videos relating to this, although I find such videos tend to skip over finer details.

As a matter of interest, there should be a cable between the Z-SUS and the buffers along the bottom of the display panel. Try unplugging that and see if Vs stays high. Couldn't download the service manual last night,
but I've had the occasional faulty panel dragging things down until I unplugged that lead. Just an idea.

Impressed by your diction, btw. Should gladden the cockles of Turnip's heart.

Cornboats:
Hi. I disconnected bottom buffers as 1 of the first checks. Y sus and z sus stay on which made me think these may be the culprit so I changed for another set of known working. Same symptons I'm afraid.

That's a worry, then. I'd be inclined to suspect the display panel itself. You appear to have run out of PCBs
to replace.

Cornboats:
I think you might be right.
No one else has come back to me regarding how to test y drive buffer boards. Pity!

Thanks for you're input anyway.
