Bunker, Thanks for your assistance so far, and
 I did not have my meter set right when I last used it. I had it set to DCV instead of VAC. Actually, my meter says ACV. I do have power to the motherboard. Meter set to ACV 200, red probe going from left to right and black probe on metal I get, O-12.7, O/G-12.7, BRN/BLU-8.3, BLU-6.9, both greens are 0.

I have read a lot of posts about my situation and have done a bit of tinkering. I think I have figured out how to be able to add pictures on the site also.

Got the machine about 10 days ago and the bottom florescent light assembly had its wires cut and was sitting in the coin tray. ( Not a good sign) When plugged in, the bottom candle light flashes fast and the reels get stiff, and 61 lights up in the winner paid window, and a 0 flashes for a 1/2 second in coins played window. I believe I have got the door optics working because when door is open (put piece of plastic between optics that I've mounted on reel tray) and I push small white test switch,  the 61 goes out for a couple seconds and then comes back as 61. When I pull the piece of plastic out (door closed) and push the test switch, the 61 does not blink or have any change.... When I pull the cmos chip out for 30 seconds, put it back in, and power up the machine something flashes for a split second in the winner's paid window, but that's it, everything is blank. Seems like it can't handle what it's trying to do... Turn off the machine and back on and I get the 61. Push the test switch button and it changes to 61 1 with the ding. Shut the door, turn the reset key, and goes blank for a couple seconds and comes back with 61. It will only get to 61 1, one time after cmos chip taken out and replaced.

Button lights, and lower candle light, are the only lights that come on. Reels get stiff, but don't spin, DBV never comes on and coins just fall into coin tray. Have not been able to get any credits by pushing tiny white button on comparator board.

My best guess is that the door switches are not showing closed. I think I've got the main door optics working properly, (Although both optic red wires meter out at 22.2)but I think there's an issue with the cash can door switch/wiring/power. First thing I did was cut the cash can switch wires and twisted them together, but the main door optics wouldn't work properly like that. The cash can switch wires are blue/green and green/green. I have to make connection with the blue-green wire to the metal cabinet for my main door optics to work properly. With meter set to ACV 200 and red probe on blue-green wire, black probe on metal it reads 22.2. With red probe on green wire and black probe on metal, it reads 0. Traced the blue-green wire and it comes from the cabinet optics. The green wire goes to the motherboard and it has conductivity but reads 0 V. The pin it connects to shows 20 V.

That's all I've got for now, although that's plenty to chew on. Any help on what I should do to troubleshoot this further is much appreciated.

Hello all I need help setting up and programming my mx6..
If any one can help me or point me in the right direction.

I have tried everything but I can't get it right . All ways come back with errors.

The game is called silk road. 5 line x 10 bet

On the reels, only the first set of symbols above the seam match up

Ok, that switch is on the door along with the coin in switch. 

I would look for obvious sign of shorting at the switch.  Usually the door switch has heat shrink on connections.  Also look at wires to and from meter.  You could disconnect the drop (cash box)  meter and see it fuse is ok when switch is closed. 
        I added a drop switch to a door.  The wires can be routed behind a plate.  That's where they were cut and taped.  If fuse doesn't blow with bottom door molex disconnected, you may want to check at switch on door.
