WTB : ARIII Working PSU for Championship Sprint

I would try cleaning the edge connector between the CPU board & Video board and see what that does and if that don't fix it then try reseating all the chips.
 
okay we pulled the roms out today, and they were pretty dirty, some the legs broke off when trying to clean (did reburn two using MAME set) and also pulled the edge connector off and cleaned that, and now have it 95% working and plays great! love this game, has a few small glitches on the moving barriers, the wrenches and small stuff, that really doesnt affect gameplay that much, but cant find which rom is what graphic, does anyone have the schematics? or anything that can help track down this, thanks :)
