12/23/2024: Localization News - Team Innocent
Hmm.. well, I may have to start fooling around with my logic probe to see if the Ram/CPU are bad.

PC-FX Localization for Team Innocent is released, a pre-Christmas gift!! In a twist, it feels like the NEC PC-FX got more attention in 2024 than any other time I can remember! Caveat: The localizers consider the "v0.9" patch a BETA as it still faces technical hurdles to eventually subtitle the FMV scenes, but they consider it very much playable. |

Console Repair/Mod Center / Turbo Duo Issue - Need HELP - Possible 5v short
11/12/2014, 09:33 AM
Hey all,
So I've picked up a Duo a few months back from Ebay that was labeled as not working. Whoever tried to replace all the caps did a real hack job on this one....... All the caps were the same, the solder was crappy, and a solder pad was missing. There's also some brown gunk here and there (soda?)..
Anyway, I replaced all the caps, cleaned up the PCB as best as I could, jumped a trace to remedy the missing solder pad... and now I'm pretty sure I'm facing a 5v short somewhere that I haven't located yet. I still have to test the entire board with my multimeter to find the 5v points..
Here are the symptoms:
1) when an HuCard is inserted, there's nothing but a black screen and just a sound from the intro I guess (Keith Courage)... the sound is just continuous, and every time you turn it off and back on, a different sound it playing and still continuous.
2) when turning it on without a HuCard to boot a CD, I get nothing but a white screen. Nothing else..
Now I've done enough research to find this issue but I can't put my finger on it. The only reason why I think it's a short is because of a video posted on Youtube by Gametech about a Duo that has a 5v rail short (it did the same thing sort of, although regardless of Hucard or CD).
So if anybody has any pointers, please help me find this issue so I can get this thing rolling!
