williams Flash help

[slither]

I got a call today from a friends father who has a Williams Flash machine. The game starts fine, scores etc, but the flipprs are dead, also no pop bumpers or slingshots, ball ejects fine, kick out hole works, drop targets reset, but flipper and some solenoids dead. I checked all fuses, connectors etc, all good. The mpu and driver were both rebuilt about a year ago by bruno(mindstorm), and 40 pin was replaced, no visible signs of board damage, thet said they were playing and those parts went dead. Any ideas on what to look for?

Thanks..

First, check for any broken common wire at a coil lugs under the PF...
Second, could be an issue on the driver board (special solenoids, or associated connectors)

Cheers,
