Tech: Berzerk help

Hi- I recently picked up a decent Berzerk cabinet, very clean inside
and in pretty good shape overall. The game didn't work, just garbage
on the screen, and no beeps when turned on. I noticed the typical
battery acid damage on the ZPU board, and assumed that was the
problem. I borrowed another ZPU board from a friend, put it in, and
the game game up and worked fine. About a week or two ago, I turned
on the game, and got just a bunch of lines on the screen, and no
beeps. I took out my friend's board and bought another working ZPU
board from another friend. I put that one in, and got the same lines
on the screen, and no self-test beeps. I thought it might be a power
issue, so I checked the voltage at TP4 on the VSU-1000 board, and it
appears that the voltage is fine. So now where do I look next? Any
ideas? Thanks for your help!
