Can you check the voltages on the power connector that plugs into the DMD panel itself? There are two rails, one at about -108V and the other at about -120, that Chris is talking about. It's possible that the DMD panel itself is pulling them to the same voltage, which is bad.
(Edit - if anyone has any dead DMD panels, and doesn't mind freighting them, I'm interested in buying them. Both totally dead and outgassed.)

Yep, it definitely does happen. I suspect that it's the electronics going bad when that happens, rather than the plasma panel itself, so probably repairable (though would often take a lot of work).

-136
At least the 12V differential is there. Well, 14V, but that's probably not fatal, so the row driver logic should be happy. As Chris says, I'd definitely check the power supply, that seems too far out of spec. Maybe it is low enough that it's exploded the row driver or panel. I'd expect the panel to do weird things for a while before failing, though.
