Quoted from edwood:So an update, and some help would be LOVELY if anyone can understand what's needed next:
Rebuilt the entire DMD section again... New diodes, and zeners, resistors (ceramics still measured good), all transistors...
Now the voltages are:
66v (instead of 68v)
-110v
-88v (!!?!)
These are voltages AT the pins, DMD unplugged. 12V and 5V still reading good.
So how do I get those extra 10 volts?? Like I wouldn't know exactly which component would be the "likely culprit"...
I would THINK the 66v is close enough (?)...
I can fix stuff, but I don't quite know those electrical intricacies yet.
Anyone who KNOWS, I'd love to understand it, and otherwise, ideas welcome.
Thanks in advance everyone!
Just throw a new board or send it to someone who does repairs...Your time and money You've probably spent double (especially if the boards caught on fire!!) it's not worth the effort.
