I've purchased a Simpsons PCB that is having graphics glitches. All of the playable characters and enemies are only partially displayed. I've run the RAM / ROM tests and everything tests out OK. +5V must also be good as I'm running this PCB in my TMNT cab that works fine. Anyone got any ideas on what IC may be bad? One of the Konami 005273 components at S31 look like someone attempted a repair with some resistors soldered in place. Not sure what these components are for. I'm presuming they are custom resistors. I've reseated all the socketed chips, one chip had a leg out of the socket touching another chip and one of the CPU chips had a bent leg that I straighten but it didn't appear to be touching any other legs. I don't see any broken traces. Any help would be appreciated.
