Could you post some pics of the damaged areas if possible?

Also check to see if any coils have locked on and been burnt under the playfield, It is quite common for solenoids to lock on when the machine is powered up with no CPU board connected (any thing can lock on when a pin is powered up with out a cpu).

I might be wrong about the coils locking on in your machine but it's worth mentioning.

hope you get it all sorted.
