First off I want to say this is my first post and want to say that I love this forum so far, I've found tons of info on arcade cabs here and more yet to find. I'd hoped my first post would be about the custom cab I'm planning but that will come later.
I have two consoles I'm working on right now that I'm having issues with, a model 2 Genesis and a SHVC SNES. Both are out of an eBay lot that I got for a decent price and now trying to flip these to recoup money, and were pretty rough when I got them...looked like they had been pulled out of a mud hole and dried out during shipping. The genesis now has power and is getting video to the tv but never makes it past the initial licensing info, goes to a black screen and nothing else. I've tried different cables, games, and power supply with same result...said cables and games work fine on other consoles. Caps visually look ok and connector has been cleaned and re-tensioned.
The SNES has a solid multi out and power but only gets a black screen. I tried all of the same stuff with it I did with the genesis with the same results. Connector looks good and caps seem to be ok, also tried with SHVC disconnected. From what I've read it could have a bad CPU or PPU but haven't found much on how to confirm this.
I can upload pictures later tonight if it will help, thanks.
