I'm currently working on my Space Riders, so I'll try to offer some help.
Diode CR22 is part of the Flipper Relay kit. (I don't think it's part of the problem you're currently experiencing).
In the video you've shared, there are solenoids firing, so your solenoid circuit must be getting power. Can you post a clearer picture of your Processor PCB? and a clear picture of your AUX PCB?
The solenoid circuit provides the power to the solenoids, the logic circuit provides the signals that activate the solenoids (and the lamps). When you pull the Logic fuse, the logic circuit is unpowered, and thus no longer sends the incorrect activation signals to the solenoids and lamps.
My guess at this point is that your game ROMs or MPU are causing the issue. I can check my boards when I get home, but my first guess is actually that your ROMs are in the wrong slots (based on this image https://www.pinwiki.com/wiki/images/5/57/Atari-space-riders-mpu.jpg from https://www.pinwiki.com/wiki/index.php?title=Atari_Repair)
Can you confirm that you have checked all the fuses to confirm they are the correct ratings? F1 on the power supply (bottom fuse) should be changed to a 5A slo-blo (from 15A fast blow).
