Finally got my BTTF back up and semi working
But have NO playfield lights or drop targets :(
All the flashers work, sound, bumpers, flippers, etc. all good.

just not lights or drops these are ALL the insert lights

I installed a new PS which got it up and going but not sure where to start
to narrow this down.

any ideas???
 
well this problem solved.
Big thanks to Portland Pinabll Repair who was out at the Portland Retro Gaming expo this weekend who helped me go through this pin.

Bad bridge rectifiers, blowing fuses.

is this really the best way to do these?
seems like there should be a better replacement for something like this.
what a PITA
 
Pins are a different beast than arcades. Can't just slap a power supply in there and fix the power issues that way.

I would love to see if JJP is making any changes to the de-facto power supply model that pins have been following more or less the same for 30 years for Wizard of Oz, but they haven't said anything.

At any rate, replacing bridge rectifiers is real easy. I had to replace two on my STTNG, and they're like a buck fifty each. :)
