it's that same old saying "you gotta start somewhere" ;-)
10/10 for reading up the tech info and having a go, that's a good step, and with someone to assist pointing out some common probs, you should be a pro in no time ;-)
If there were 10 commandments for pinball fixing, i'm sure it would include something like:
- Make sure that 5volt, 12volt, and all other voltages are correct! (not "nearly correct", but exactly correct!)
- check/replug ALL connectors.
- check/replug ALL I.C. sockets.
- check for (battery)ACID damage and clean the board/replace tracks.
- check ALL fuses, and PULL THEM OUT OF THE FUSE-HOLDER to measure!!!!! (this catches everyone).
- Change faulty/all capacitors, they always die!
then, if all the above is good, move onto fault-finding of components, which means you'll need a little more understanding of the circuitry and how things control eachother and so forth.....that all comes with playing around...
Best of all, everyone here on AP will chime in and give you tips galore....
MM.
