Quoted from xeneize:cody_chunn Self diagnostics reports no errors.
I was installing the huge plastic protector set from Pinbits which is a COMPLETE pain in the arse. A, simply because of how hard it is to access the rear-most plastics. B, because they were missing 1 out of 3 holes across the set for correct mounting.
So, yeah... plastic protectors installed, but game no longer works... that's pinball for you!
Did you know you can lift the whole playfield up and out so it’s balancing on the brackets - then either lay the wheels back on the lip under the dmd on a towel or do what I did and rest the kicker mechs on the receiver mechanism. You can then access all the back area easily.
