This phantom of the opera I picked up keeps blowing f1 on the ppb board. The left side of the GI is what it powers. Any ideas? I'm sure it's something simple I'm overlooking.

I re pinned both sides of the power supply at cn8

I reflowed the pins on the back of the ppb board too.

I inspected the GI chain to see if I could see any noticbly shorted parts but couldn't see any

I've got the schematics on it in the manual. I know I've got to just be missing something simple. I guess I'm going to keep checking for shorts in the line

If anyone has any ideas please feel free. I'm open to any suggestions at this point

I've got continuity between pins 4 and 9 on j5 to the ppb board. Would a short across a bulb socket cause that?

Unplugged the back board lights in the back of the playfield and they light with no blowing my circuit breaker. Must have some damaged sockets back there I missed. Thanks a ton guys
