Quoted from EvanDickson:Good idea. I popped the GI fuse to remove them from the equation and no change. I'll try with all fuses that aren't 5V or display power later to do the same in case of ground shorts with a coil somewhere.
You can't remove the solenoid fuse game won't boot up without the zero cross (or run, for that matter)
Look for a diode on the coin door shorted. Boot the game up with the coin door connector disconnected to check if there's something amiss there.
Quoted from EvanDickson:Is that not the 11,700 ufd one that I replaced?
Nope, that's your +5 filter cap. HV filter cap is the one at the top with the 350v rating on it. What is your display voltage set to? <190vdc and some displays can flicker. (I know "everyone" says to set your display voltage to 170-175, but factory spec is 190)
Also try one display hooked up only, see if you get the same results.
