Hello all! My name is Ricardo and I’ve been trying to get help on game systems that are problematic but can’t seem to find the correct issue as to what’s going on with these systems.... I am not a hardcore collector but more of a repairman 👨*🔧 for computers electronics and video games and consoles. I’m very passionate about seeing older systems live longer so folks could get to enjoy them like we all did. I try my best to look up and research problems that I’m having before you make a thread. The following systems I’m trying to repair are

1) a Model 2 Genesis, motherboard rev VA0. Games play and work fine, no graphical glitches.. just freezes.

2) a SNES og model w the sound module. It turns on but no signal or audio whether RF or multi out. TV always says no signal as well.

Please lemme know what I should do to approach these systems thanks.
