I have a Stargate machine that has power issues. First I got intermittent errors on startup, then it went dead completely. I opened it up and when powered on, only 2 of the 3 LEDs on the PS were on. I turned it off, checked the connections, and when I turned it on again now none of the LED's come on. Additionally I don't hear the familiar hum and "thunk" of the relay. I tested the fuses (all good) and visually inspected the board, and I do see that one of the pins on the plug leading to the large black heat sink looks burned (see photo).
I gather I need a new power supply, but how do I know if it's the PS board or the big transformer that's bad? Is it normal not to hear the hum and relay "thunk" if it's just the board? I thought it was the transformer that made those sounds. Not sure which wires to test on the transformer to see if it's outputting power.
Lastly, if I have a bad PS, I'd prefer to buy a new switching model rather than rebuild this one (I care more about reliability than I do original innards). Where can I get one of these?
Any advice is appreciated.
