So, new firmware for the Neo SD Loader. So I thought I'd revisit my modified Neo Geo CD front loader. Only to find it won't power on... checked the power supply, it seems fine. Tried to reseat things, but still nothing. I hear a pop from the audio when I press the power button (not a bad pop, just a "contact made" sort of pop) but no video or LED. Not sure where to start, I dont see a fuse anywhere and am not sure where I can test voltages to see where the failure is. Any help is appreciated.
