Repairer: channelmaniac

Symptom: Crosshatch of Death

This board does not suffer from the same battery damage induced Crosshatch of Death as the old style 4 slot board. The old-style 4 slot board's problem is one of legendary status and it should be documented that it is the ONLY board to consistently suffer from that kind of problem.

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.
