Could be a processor problem. they make snes cartridges that are made to troubleshoot specific codes that you can look up. Please post an update video🙏🏻
I MIGHT have figured out the issue. I was poking around looking for shorts when i found a shorted capacitor... which in turn led me to a shorted inductor L1. I ordered new parts and will do an update when i get them.
I had a similar issue it turns out that the cartridge slot needs to be cleaned of corrosion of any dirt, dust, same for the cartridges. If your model is the one where you can remove the cartridge pin connector and clean or replace it. I would also recommend replacing the pico fuse, sometimes it can be low voltage from the actual power supply that plugs into the wall. And it could very well be the on board PPU or CPU chips even RAM which you could replace.
@@Retro_Cave Yep, I absolutely agree with you. In addition, the risk of destroying various components and/or the circuit board is quite high, as the processing temperature for lead-free solder is significantly higher. The longevity of the solder joints is also highly questionable.
Both my SNES's were working until i started messing with mine, and i did something to it. It didn't just stop working on its own. I'm STILL trying to figure out what i did to it.
That would be the key step in the repair is to understand what you did when you first started tinkering. Sometimes, accidental tinkering can result in a loss. What was the cause that got you to crack it open? My guess when the fuse blew its a possibility it also knocked some of the ppu or cpu ic's out. Usually a blow fuse is a easy fix but if more current went in after the fuse blew by tinkering that could have caused the damage. @Retro_Cave
