Good day, all.
I replaced the drop targets and pop bumpers on my Joker Poker a few
days ago. While I was at it, I added some Cointaker LEDs behind the
backglass, including some nifty 455 flashers in behind the "Joker
Poker" title.
A while afterwards, I noticed the 4-digit display (credits/ball in
play) display wasn't working at all. Since I did the ground mods,
disabled the slam switches, replaced the battery with isolated ones
and set it up for free play, this machine has worked flawlessly.
I cleaned the fingers on all the connectors when I did the ground
mods. I just gave them a quick cleaning again on the display, and on
the A1-J2 and A1-J3. Still nothing on the 4-digit display.
After doing some reading on here, I thought it might be a power supply
issue. I checked the voltages on the power supply. The 12, 5, 4 and 8
volt ones are fine. The 60 reads 38 and the 42 reads 20. Is that
normal?? The voltage is also getting to the display, so I don't
believe it is a connector issue. I see there is a trim pot on the
power supply...can I adjust on this? Should I?
Any ideas? The four 6-digit displays are fine, and the game still
plays like a champ.
Is it safe to play the game without this display on? Will it damage
any of the boards?
Thanks so much for any and all advice.
