I am a very novice board repair-er and I have had hit and miss results. I have had the best luck swapping out wrenched caps, repairing physical damage, and re-burning bad EPROMS. Anything past this has been awful for me. At what point do you throw in the towel on fixing glitchy boards?
Aero Fighters/Sonic Wings - huge PCB, bought it without sound. It was fine for a bit, but now I have bad graphics glitches, it is still playable. When the PCB is flexed, sometimes full sound will kick in. No visible board damage. Time for the scrap pile, I'm sick of it. Just replace it...it is a common and inexpensive PCB.
Raiden II - no visible damage, I've gone round and round with this one. I had another parts Raiden II PCB with a bad custom. My logic probe said I had bad RAM, so I swapped that out. I also tried to swap out a mask rom. This is another scrapper, and not easily replaced on the cheap.
Out Run - bought it dead (expensive set), was able to do some basic physical repairs and I got it into test mode. The self test flagged a RAM chip as bad, so I spent $12 and a couple of hours installing. Still dead, same chip is flagged as bad. Bought a Turbo Outrun boardset, am just going to swap everything over and call it a day.
What do ya'll do? Throw it in a box? Have a broken PCB sale to try and get your money out of 'em?
