I had just installed an LED upgrade and multiple on/offs throughout to test and find lights was accomplished fine. At the very end when I installed the under POA mini playfield lights and put back together I no longer had any GI lights and the CPU no longer boots (D19 LED stays on). Unplug all but power from CPU board and the board will boot. Add plugs/cables back to it and J113 (power driver board to cpu board ribbon cable) causes the no boot. The ribbon cable tests good in my STTNG. The cpu board boots fine with all connectors attached when placed in the STTNG, so I think my CPU board is good. Tested the GI connectors at J120/121 on power driver board and getting about 7.0 VAC which is good. Fuses are all good. I have no GI lights anywhere. Do I have a lamp matrix problem or any other ideas for me to chase down??
