Start with your favorite part of the machine - the connectors !

IDC connectors are crap and this will most likely be your problem. Push in the Red/Brown wire J133 Pin1 -

Then grab the old MM and set to "Continuity" - and buzz out J133 Pin1 to the Red/Brown wire on each of the lamps.. There could be a broken wire.

Q90 could be an issue here, but it was all working fine before you stripped the playfield

Also look for any shorts from other parts under the playfield to any of the lamps or their holders.

Do the same for the j133 Pin 2 Red / Black.. Follow the wires to the respective lamps in that row..
