Working on a Party Animal where the pop bumpers and saucers at the top (all 3 saucers and all three pops) started working intermittently, then just quit all together. The initial problems were that they would all work for a few minutes then just die off. Now they are all just dead. I'm pretty good with Bally -35 early SS but not much experience with these 6803 games. I can see the MPU combines much of the -35 era board features in one, but I'd appreciate a nudge in the right direction. Any usual suspects on this era machine?
I've checked the driver transistors in circuit and all seem to be good. Voltages seem to be good...
Thanks all.
