Issue with SIGMA POKER-HR-IM Model I2211

[Edwin Wunderlich]

I have a SIGMA POKER-HR-IM Model I2211 that I am trying to fix.  I found a defective +5 vdc Power Supply and replaced it with one recommended on this Forum.  I now have +5vdc and +12 vdc.  I also confirmed that the Monitor is good, as when I unplug it, I can see the raster collapse and hear the HV.  I suspect an issue with the Main Board, but need to know if anyone out knows where to send for check / repair.  Thank You !

I assume you have tried to put a quarter in to verify that the game is not playing. I agree that it is likely that the monitor works but sometimes monitors have HV but do not display.
Is tnere a reset button of any kind inside the machine?

There is a Reset Button inside, it does nothing and a coin just falls through as if the coin comparator has no power.  I did verify I have 5.08 vdc on the Main Board.  So, at this point I was looking to have the Main Board tested.  Thank You for taking time to reply ! I'm also interested in a Manual so still searching for that.
