I have a client in which I helped restore a Smash T.V. cab, but when we had gotten the board set we didn't have a power harness for the sound board. At that time I made a small jerry rig with hookup wires and it worked fine until I could make my own harness. I made the harness trying to copy the schematics as carefully as possible, but the first run I shorted the power supply.....in fact we thought the power supply was dead because it wouldn't bother turning on when not plugged into the game. Anyways, we replaced the power supply and yet it still shorts things out, but I know its not the PSU this time, its my dam harness. So I re-wire the harness and turn it on, I get a strange audio feedback and then the ribbon cable starts to melt. So apparently I fed a voltage through the ground circuit on the sound board and it went straight through the ribbon cable and well you know..... CPU board checks out fine, but I dunno about the sound board until I got a replacement ribbon cable and an official power harness the other day. I plugged it up this past sunday and get nothing.....a nice 40 minute rainy day drive for nothing...
My boss thinks the sound board has burned out chips since there is no visible damage. I think so too, but I need to know if I can find an easy replacement and swap out the ROMs or should I find someone who knows how to fix these things?
