Crosshatch of Death: Neo MV1FZS

A customer shipped me a Neo Geo MV1FZS system for repair that was stuck at a Crosshatch.

Powered up the board and duplicated the symptoms. Looked for obvious signs of damage and found where the bottom of the board was gouged by something.

Repaired 3 broken traces connecting to the cartridge slot resolve the crosshatch problem and repaired another 3 broken traces causing corrupt video.

Always check the boards you are working on for signs of physical damage. It's pretty common on arcade boards.

Enjoy!

Awesome Info as always!!!Thank You..

yeah for months i was stuck on a 2 slot come to find out 4 traces was gouged by something. so i scraped either side of these small traces and bridged them with strands of wire and layered on some nail polish. can barely tell afterwards where i repaired the board.
