Greetings all, hope everyone had a good holiday.
The situation is a Strong Switching power supply, model 628005. AC volts are on pins 2 and 4, muffin fans, lamphouse blower and ignitor work in manual, and AC volts are on 5 and 6 when lamphouse is switched on (switched to local not auto), but there is no power relay operation in power supply, no no-load DC voltage and finally no lamp operation.
This arrived DOA.
After checking out some of Mark Gulbrandsen's posts on typical Strong power supply failures and visually looking over all the components, checking the big fuse etc, I only found a small burned out capacitor (C55) on the motherboard. Before replacing just that and risking some other kind of subsequent implosion (or worse), is there just another motherboard I can replace it with? (p/n 61-72002) Any other comments?
