Joker Poker displays go dim

Post by Zog on Thu May 18, 2017 6:39 pm

I've got a Joker Poker that all the ground mods, slam switch mod and battery relocation has been done on. I've had the machine for over five years, and it's been bulletproof...until recently. It has all the original boards.

When I turn the machine on, everything boots up properly. After about thirty seconds, all five displays start flickering slightly, and then gradually go very dim. I checked the voltages with the outputs unhooked, and the 62 volt is at 61, and the 42 is at 43. With everything hooked up, they are at 44 and 25 volts.  

Other than that, the machine plays perfectly. I'm not sure where to go from here.

Do you think it's the power supply? I'd like to keep the original main and driver board, rather than go with the Pascal or NiWumph. I wouldn't mind going to the GPE or Rottendog power supply, tho.

Does anyone have a spare working power supply I could try to make sure before I spend $$?

Probably cheapest to re-built the high voltage section of the power board. I agree though, it would be nice to swap in a known working board to know for sure what it is. Unfortunately I don't have one.
