Apologies if I'm posting in the wrong thread here, I'm new to this forum, it would be nice if the moderator could switch this to the right thread. I've been having issues with my Model 2 NTSC J VA8 Sega Saturn, the controller ports are not working with no input. I'm used to encountering Black Screen and Laser faults but this is my first time ever encountering a fault like this. I have modded and fixed many Saturns using these mods and repair kits. But this fault continues to persist. It has been modded with a 50/60hz Switch, Region Free Bios and an Fram mod and after discovering this fault, the motherboard has been recapped using a kit from Console5, reflow the controller connectors, and I even have new EMI filters also from Console5 which replaced the ones near the controller ports along with a test of all of the SMD Fuses L1 through L10 which check out fine. Along with a clean of the Controller Ports using IPA 99% and Contact Cleaner. But despite the mods and the fixes, the console does not detect any input from the controller. And I have tried various of my Sega Saturn Pads which work fine on other Saturns but not this one. I essentially have the same fault as the one in this video youtu.be/WwpV7tKmYMY?si=zViFeCzHSHKpBzIn
Has anyone encountered or fixed a fault like this before? Could it be a bad PSU? Or something on the controller circuit has failed? Or are the controller ports damaged? Which looks to be in perfect condition. I don't see any corrosion, no visible damage, no bent pins. I also swapped out the bios with another, i did accidently break 2 traces, but i fixed those traces and tested it with this other bios and no fix. The same problem occurs. No input from the controller and i'm stuck on that menu.
