This one was not powering up, so I cracked it open.

The on-board fuse was still good. There was 120 AC,
and about 330 DC on the first rectifier. But
there were no DC voltages going to the next board.

So it's most likely a power supply issue, but as you
know, modern switching power supplies are very
complex, and are difficult to troubleshoot, especially
without a proper schematic.

Any advice is appreciated.

I have the test equipment....haven't you been paying attention to my
posts?


** I bet you have not got a iso-transformer or any clue of how to use it.

Amateurs should NEVER touch a mains switcher supply.
