those two power supplies control all functions of the game. one is +5vdc, the other is +12vdc,  the color of the wire will indicate which power supply is bad.  usually red wire =+5 vdc, Orange wire =+12 vdc.  the one with no light is probably bad. without these two voltages the game board won't generate the signals that are fed to the monitor, thus no picture. You could get a good idea if your monitor is good, when you turn it off, there should be a bright flash in the center of the screen, also with power applied to the machine, if you run your hand across the face of the picture tube you should feel a static electricity. 

Hope this helps

what do you mean about the color of the wire will indicate which supply is bad? there is a flash on the monitor when machine is powered down. the left supply is without the light & the right light is on. do you know how much this power supply would cost? where to buy one? would you need more info off machine to know cost? much thanks!

Are these the power supplys you have? I have a box of parts from a Sigma Black Jack machine I had.. I have just about everything except the monitor.. The power supplys are marked on the from 5V & 12V, what one does not have the light on?

I'd take $30 plus shipping. It should fit it the small priority mail box. They were $5.85 or so, unless they went up again?

I can guaranteed that it works. It was pulled from a working machine. I do have a Paypal account but don't want to deal with credit cards. Mines is thru my banks checking account. I will accept Postal Money orders or Personal checks.

Thanks Gary
