As the title says. I was working on my Mortal Kombat 2 after installing some new chips. Everything was working except the audio board was acting up. I went to check the voltages at the pins on the audio board. I must've shorted something because as soon as the probe touched the whole thing just shut down. I have a suzohapp switching power supply. The power supply turns on for a second when I try to turn the machine on then turns off. Sometimes the powersupply will come on and I'll just hear a light buzzing noise of some sort. The monitor powers on fine with neck glow and whatnot, but nothing on either the mk2 pcb or the audio board.
