Hi,
I have a Playgirl Queen (3 reel machine) which is set to payout level 4. I have tried to change the level by following the reset procedure by pushing the reset button PSW1 on the door display board and / or the tiny black button on the power supply next to the key switch. There are no buttons with color tabs in the machine and the button on the display board labeled PSW1 does not do anything that I can see. Nothing changes the display. I must be missing something.
Any help is appreciated. I also see what looks like a photo detector on the door latch, is this to keep the machine from operating with the door open?.
