Quoted from Drewscruis:The axial electrolytic cap will dry out over time. The two disc caps should be fine.
Yes, these displays are 35 years old so the electrolytic capacitors probably are going bad.

I've got a Haunted House I'm restoring for a friend. It also has the same display pulse/flickering yours does despite the fact I have completely rebuilt the power supply board with all new electrolytic capacitors and connectors. I guess I will have to whip out my CapAnalyzer 88A and test those electrolytic caps on each display board.
I believe the aftermarket boards are designed to ignore the slam switches and boot up regardless of whether the slam switches are open or closed.
Quoted from pindoc1:Does this mean the slam switch is inoperative or just ignores lack of contact on boot up?
I think on some aftermarket boards, the slam switch is not even written into the game software.
