I have a WG 25K7917. The AC power appears to go into a Peter Chou PS, then to the isolation transformer, then to the monitor via a 3 pin molex. I know the JPAC can't power the monitor, and I know that Ultimarc says you should disconnect the PS completely.
I've read 20 threads on this topic but still can't find an answer - how does the monitor receive power if I disconnect the PS? I suspect I need to run an AC line directly to the isolation transformer - is this correct?
