Virgo heads up

[ZOOTECH]

I have a few Virgos we got cheap because of broken displays/touch screen from lease returns.
The slide out keyboard was dead (no LEDS) on one machine after display was replaced.
I tried everything short of the PCU board, and the firmware updated to the 8.2 version.
It was cloned from an identical working machine, so I thought all my settings would be good.
I started hunting for items to check, or change, and somehow came across this setting
under System Settings – Operation Settings “Key Touch Sound at Initial Point”.
I put a check mark in the box, and the keyboard started working (verified by un-checking
and the keyboard was inop). What is that function, and why would the kbd work on a
machine with no check mark there? There must be something else causing this symptom.
Have you heard of this, if so, please enlighten me?
I am going to leave it as is with the check mark, and give machine a full going over operation wise.
Have a great weekend.

Spoke too soon, keyboard is not working whether checked or not, back to square one - bummer, ruined the weekend. (:

Tried a known working keyboard without a change.

I did a little searching, and there's a member here that has some considerable experience on this inoperative keyboard issue:
MX-3100N pull out keyboard not responding.

Maybe he can help you. =^..^=

if you have replaced the USB conv pub and keyboard, then replace mother-hub pub. have had this pwb fail, has the USB hub on it for keyboard and USB ports, check electrical section in service manual.

That was the first board I tried from a working machine, and then the MFP. Neither helped, until I put a check in the box mentioned in the op. It worked until I went to show a tech, and then I shot myself in the foot. I regret posting too soon, but I want to thank you all for your help. I'm beginning a new start for the long weekend (working on the cold ones), and will try again on Tuesday.
Cheers everyone!!!

Sorry for not posting the repair earlier; the problem was the cable to the USB converter pwb had a broken 5 volt wire that was intermittent.
This is the 'scissor' cable (p/n DHAI-4704FCPZ) that flexes when the keyboard is slid out.

Crazy. Nice find.
