Any good sites/books to learn how to repair electronics?

[Benjamin]

In searching for a way around my MV-1F's cross hatch of death, I came across solutions stating to check for a "broken address line on cart slot" and a "broken data line on cart slot," along with some other stuff like "reflowing" things and whatnot. I'm ignorant here, and I really shouldn't be given all the stuff I have. Any suggestions on how I can learn how to diagnose a board and make repairs on my own? I'd like to know so if and when my consoles and PCBs die, I would be in a position to fix them.

It's not so easy to just pick up a book and learn everything... Different PCBs have different common areas of failure. You should just stay on Neo-Geo.com and ask for help from the tech gurus there.

However, a good place to start is to buy a multimeter with a resistance function (preferably one that beeps). You can use that to test a trace to see if it's broken or good. Thing is though, in the environment of a complex PCB, the resistance (or continuity as I know it) can give false readings because all those traces can be interconnected in one way or another.

How I first gained experience with a soldering iron is finding a junk piece of equipment (check your local thrift or look around on garbage day) and practicing de-soldering/soldering components. Then once I felt comfortable with the whole thing I got a couple simple kits online for like $5-10 each and a pair of helping hands, and then built them (one was a voice synthesizer, the other was a small pong game). They're really straightforward since they just tell you where to put each component, but it gives you an idea for how stuff goes together.

As Guntz said, for more complex troubleshooting a multimeter is essential, but for basic work with components you still need soldering iron experience before diving in.

Thanks for the multimeter suggestion. I asked here since it seems like more people here post about different projects and such well beyond basic troubleshooting. I've been wanting to know how to get to that point.

Easiest method is to apply university of applied sciences electronics engineer studies, and you get to calculate all the nesesary things like I do. Only half year gone and I already did figure out my broken pre-amp and fix it. I just manually calculated the voltages and checked with multimeter are they right and found where the problem was.
