    All of my lamps that are part of the lamp matrix aren't working. The GIs work just fine and all the switches seem to be working. I checked the F114 fuse and that is fine and I checked the others just to be sure. I also checked continuity from the power supply to the power board. Any help I could get in next steps in diagnosing this would be appreciated. When I ran the test for "All Lamps" it freezes.

    Reseat your ribbon cables

    So I did this and it worked for a few min. I put the backglass on and it quit working. I tried again and nothing. Is it a bad ribbon cable? Any way to tell which one?

    Sounds like it.

    Do them one at a time and see if you can figure it out. I'd start with ribbon cable from CPU to Driver Board.

    So I replaced all of the cables and they still aren't working. I double checked the fuses again and all are good. Any assistance on next steps would be appreciated.

    Is the connector to those GI lamps in good shape?Any signs of burns on the board?Are header pins in good shape not dull or flaky?

    hmmmm if i remember the power source for the lights has a cap that sometimes the trace fails under it or the transistor.....take meter to it and see if you have your lamp voltage.....
