I have a VLT110-4302 throwing powerfail when connected.
None of the caps appear to be bad, so I checked them as best as I could with a fluke.
The input rectifier seems to be fine, and the main caps both go to 160volts, which seems sane.
The output rails don't turn on at any point.
What steps should I take to diagnose the problem?
Thanks in advance,
bob

I checked the startup resistors running to the KA3882, and they seem to be close enough to their marked values.
Got it fixed, the problem was the equivalent of C10 in this example circuit: https://datasheet.datasheetarchive.com/originals/library/Datasheet-01/DSA0017127.pdf
