I'm in the process of building my first MAME cabinet (by the Book of course) which got me interested in owning original arcade classics. My question is where is the best place to learn how to fix non working games (PCB's, monitors, etc.) as these can be purchase and possibly repaired much cheaper than buying a working game. I'm a complete beginner with electronics, so I need to start at step 1.
Any helpful points of direction are appreciated.
