Can anyone help me diagnose missing -98v on my DE power board (520-5047-01 Rev B)?
on the CN5X6 power out to DMD connector I should get -98v and -110v. I’m actually getting -0.2v and -150v.
before I start working through replacing each of the components, i’m hoping someone who can read schematic properly might help me pinpoint the likeliest candidates.
The caps and resistors all seem to check out fine on a multimeter. Don’t think I can test the diodes and transistors without removing them though.
the board has some corrosion etc but nothing stands out
