I'm trying to send a MOV file extension so you can see what happens.  The "reels" just start moving a bit and jumping and the display keeps

Just make a YouTube video and post the link. 

So, all of the 5 resistors are weak, I don't have the correct resistors for the machine, and I ordered them.
What is happening, the replaced resistors work for a few spins then a code 41, 42 throws up, I clear it and it works for awhile.

From what I have observed is the:
quarter system works
hopper works
buttons don't work
LCD works
key switch works
correct payout works
goes into free play every now and then
speaker works
door optics works

Please refrain from double-posting for the same issue. Your (mostly) duplicate post was removed.

Hopefully one of our Sigma pros can chime in soon.

The grey switch monitors the position of the pull handle unlock solenoid lever. If you still have the cover I'd tape or glue it back on to protect the electronics.

The power supply doesn't have the EMI filter, it's been removed.

The Yellow Dot power supply provides 24v to the fluorescent light electronic ballast. Are there fluorescent light starters on the backside of the main door? If so you have a RED Dot and the fluorescents are on 110v.

So if the fluorescent lights are on there's 110v power to the power supply.

Appears as though you're not getting +5VDC to the CPU and other devices.

That would be the 5amp fuse F3 (9.5VAC to +5VDC)

You can check the DC voltages at the 12 pin Molex plug CN-4 on the frontside of the power supply.

CN-4 pins
1) +5VDC PINK
2) +24VDC ORANGE
4) +12VDC RED
7) GROUND BLACK
11) +32VDC VIOLET

Check the voltages to ground, pin 7.

I have a ext. board and the set chips but no instructions. I know where the ext. board goes onto the CPU, but I'm not sure which set chip goes where in the ext. board. The set chips say U70 and U83. Both say Artistocrat Mk6 1-160 2008. any ideas? Thanks!
