Hey all! I'm currently fixing up a bunch of unloved PC Engine CD systems to give them new life. I recapped the CD drive and it's working flawlessly with a different IFU and with audio cds. The IFU-30A that came with it is giving me problems. It works fine for Hu-Card games and shows a picture just fine, but after a CD game starts loading all I get is a black screen. I tried cleaning the connectors and there was no improvement. Any common problems with these that would cause it? I would suspect the caps, but most of them are Elna brands and I have not heard of people recapping the IFU. Any suggestions where to start or is there a list of caps for it? Thanks!
IFU rarely fails
caps can leak
the ram board comes loose
i had bad ram in a TG-CD base so its possible, but rare
best bet is inspect the board and make sure your using a big enough supply (1.5A spec)
There are very little faults happening to the briefcase.

Have you tried to format it? There's a capacitor for saving data (C101). It can be replaced with a MAL219612473E3.
