Hello friends. I have my Bally XENON mostly working with the exception of some GI problems. There are some sockets on the left side of the playfield that aren't getting any voltage. Mainly under the plastic accent pieces on the left edge. Sockets and wiring looks good just no voltages at the socket contacts.. I pulled the lamp driver board and found that Q19 and Q29 were not giving me proper readings with my diode tester. These don't have anything to do with my problem but will be replaced anyway as I'm sure it will fix what they're supposed to light. Would anyone know how to begin to figure this out? I've come a long way with this machine which is very fun to play by the way. Any help would be so much appreciated.

It's just so dark on that side of the play field that I thought they should be on all of the time and maybe flash or something. I'll use the test mode and hopefully figure this out. Appreciate the time you folks have taken to help me.
