Hello everyone. I have a Sega Genesis Model 2 (more specifically an mk-1631). It was having problems loading known good games past the Sega Logo. These games load on two other Genesis systems that I have. So:
1. I tried to re-tension the slot. That didn't work, and the carts were still loose, so.
2. I soldered in a new cartridge slot, did a continuity test on all of the pins (it passed) so I tried again. Still, wouldn't pass the Sega screen.
3. I soldered in a new reset button at this point for good measure. The old one had a worn out rubber cap. That works correctly now.
4. So, I tested the capacitors, some were bad, so I re-capped the board. All new capacitors passed a capacitance test and the new connections passed a continuity test. So I tried again. Same issue. Won't pass the Sega screen on known good cartridges.
My question is, what do I do now since, in theory, there isn't a problem with the cartridges, cartridge slot, or capacitors?
