I had a mediocre repair day today. I decided to try a last resort approach on a PCB that has been stuck in repair hell for several years now: Raiden II. It displayed a layer of graphics resembling an Atari 2600. I killed it :-( My new rule: if it is a Seibu board, buy it working!
The next victim was my best Magic Sword C board. I went carefully around the only surface mounted chip on the board with my iron and a magnifying glass. I thought the issues it was having could be related to floating pins. In the end I killed it, the only one of several replacements that made the game halfway playable. The A and B boards are still okay, but dang it!
The only bright spot today was my POW sound repair. I found the issue using deductive reasoning and wrote a repair log for anyone with a similar problem in the future.
So, yeah, kinda spotty repair day for me.
