I have a Bally supersonic. I just had to Playfield clear-coated and it was playing great. It ended up shorting out a Playfield lamp socket to a screw of a switch.

Now when the target is hit a handful of lights on the Playfield come on. Do I have a lamp board issue, a play field issue, or an mpu issue?

Tested a new MPU and a New lamp driver board. No dice on either. Still the same lights coming on.
