I should start by saying this is my first arcade machine, so don't presume that I checked anything thats standard, I'm working off of google searches and other electronics experience. So I picked up an SF2 machine for 100 bucks, had a broken monitor but it would power up and you could play blind. Got the machine home, and now nothing works. Checked the sound wires to see if those got knocked loose, but they trace 8ohm all the way back to the jamma harness.
Then checked the power supply, and I have about an 8.5 V gap between -5 and +5 as in, if the +5 is +5, the -5 is -3.5. I'm guessing there isn't any mystery knob to widen this gap and I just have to replace the power supply? Or, can I just replace some of the components inside to easily make it output the proper voltages? I'd rather spend 2 bucks at digikey then 25 on a new supply. If I do have to get a new supply is there any other way to check to see what else could be broken so that I order all the parts I need at once?
Also stupid question, but as long as I can supply all the voltages to the board it should output sound correct? It doesn't have to have anything else hooked up.
