I recently picked up a non-working Big Red with an MV4 motherboard. The PSU was fried so I replaced it with Suzo Happ 80-0072-00. Now the system powers on, displays some blocky graphics for a second or two, then goes to the cross hatch screen of the hardware test mode. On the bright side, everything else seems to be working fine except for the motherboard. I've tried different games in different slots without success. I also cleaned the cartridge connectors and blew everything out with compressed air.
Noob alert! This is the first cabinet I've owned so I'm pretty clueless. My plan is to disconnect, remove, clean the MV4, and check for damage. I understand a leaking battery can cause issues like this so I will inspect it. Basically, I would greatly appreciate some basic step-by-step troubleshooting advice on how to proceed to get this thing up and running.
Side note: I found an unconnected cable inside the cab (see 2nd pic). It's probably irrelevant but I thought I'd mention it.
