I've gone and done it now...well sort of. So somehow, all of the screws loosened on the right sling and the entire mech fell and must have shorted something. The first indicator was that the game would boot but wouldn't start and the P1 display showed garbage. I saw the sling mech sitting on the wiring, move it out of the way (mounted it back in the stripped holes) and verified that a game started. I was satisfied and relieved, but didn't notice that the insert lights were out. I filled the holes and recounted the sling nice and snug.
I took off the lamp board and inspected the connectors but didn't see anything on either. I also didn't see anything on the auxillary lamp board either.
Any help please?
