Quoted from 20eyes:
I was working on my Bone Busters and found out the hard way why I should always have the plastic cover over the fuse block when working under the playfield. I had a washer fall and land standing straight up bridging the 2 fuses for the displays. The fuses didn't blow but something was obviously wrong with the displays glitching and freaking out. I eventually found the washer sitting there and now my BB has permanently damaged displays with random glitching. I'm sure that doesn't help your situation it just reminded me.
I labeled all the plugs.. Well, most of them.. so I could put the head in the cab of my truck with the body on its side in the bed, but the one for the display didn't get labeled. For whatever reason I didn't even think twice about the fact that my "2" plug on the driver board didn't have my label on it and off I went. Thank God the fuses did their job and popped in a HURRY.
I also had to adjust the voltage pot to get this thing to boot because it was only measuring 3.7V. To be honest I thought I torched the driver board and that's why it wouldn't boot.. Until I read the help doc online and started adjusting the pot until I hit 5.15V. Bingo, started right up.
Oh, and the fuses will definitely solve the display issue..I did a no-no and used some bigger fuses to check, because I couldn't just be patient and wait for the replacements to arrive. Whoops.
All good to go though. I have a few things to adjust (left flipper angle and right sling sensitivity) but I'm enjoying the game, and my kid loves it!
Only real bummer is the cab isn't the prettiest (really don't care, as most of my cabs are less than perfect) and there's one really nasty area by the left pop, with terrible "touch up" done to it. Maybe some day I'll give in and try to fix it, then clear coat the entire thing. At least it's not visible while playing.
