Last issue with this one. The GI lights on the head don't work (none of them). I see they run through a special light board on the underside of the pf.. does it go back through the main GI connector on the CPU board? Someone repinned the GI (and a few other connectors) but now there's one pin that's burnt up again (pin 3 from the top). Not sure if pin 3 controls that head or if it's run off some other circuit. Any help is appreciated.
