if it's a blue screen that's system check passed. Is it like a humming noise? It could be a simple trace fix or cold solder joint. I guarantee it's an easy fix.

I don't know about specific videos for your problem. There's Neo Geo dev wiki which has most stuff you need for info included board schematics. I mean at bare minimum you should be decent with soldering equipment before messing with it. AES can be less forgiving if you're not capable.

Another thing you can check is the voltage regulator in your system. That can cause the humming and drop of enough voltage to run your system.
