Got this "untested" board in the mail today for fairly cheap, turns out the sprites aren't displaying. I flexed it a bit while it was turned on, and the sprites flashed on screen for a split-second... wasn't able to get it to happen a second time.
Oh, and I'm pretty sure it's not a bootleg. It does appear to have had a wire soldered from one of the CPUs to an adjacent IC. I'll try to grab a photograph in just a minute...
Can anyone give me some pointers on how to go about repairing this?
Thanks!
edit:
Photo here. You can sort of see the wire, it's soldered on the lower side of the big square thing on the upper side of the board..

OK... I think I found the perfect flex...
Sweet, so I scored a cheap (albeit finicky) Strikers PCB :)
Strikers 1945 PCB, sprites not displaying
From messing around, I've found that dipswitch 1 is a screenflip. It doesn't allow you to play on a horizontal monitor though, all it does is flip between a Tate L and Tate R setup.
Anyway, the fix I've found for my board is to just prop up the corners with PCB pillars and put something heavy on it in the middle to flex it. Works just fine like that, so I might not bother with the processor fix if it's as troublesome as dpful said..
