Ok I googled dip switch and located them on the board. The JB 1 is the same, SW 1 has 4 settings, ON OFF ON OFF, and SW 2 is ON ON OFF OFF. Should I change them so they match yours even though it is a different game? If so what is SW 1 again as it has 4 settings and you only posted 3.

Thank you!

Sorry buzz I'm an idiot,,,,,,there are 4 dip switches on this board. Yes SW1 only has 3 but the settings are different than yours, they are all OFF.  There is an SW switch above SW2 about 1 1/2 inches up and left.

I guess I should wear my glass, your right I found the 4th one, it's marked  SW on off on off    SW 1 off on on     SW 2 off off off on  JB  off on on off on off off on
  If I was you I would write down all the settings you have before anything is changed. ( I always do this then forget where I wrote them down.) I hope someone else will jump in here, but I would think if you do change your setting to match my machine  and they are the wrong setting nothing could be harmed on your machine.

Now I know next to nothing about these machines. I can send you the extra set of chips I have and you can start working on your machine with a known good set of eproms. You can PM or email me your address and I can send them out tomorrow. Buzz

Buzz sent me a set of working proms so I put them in and it is still the same.

Today I pulled both boards out, dusted everything off, wiped inside out. The big ribbon cable that goes from top board to bottom board was all kinked up so I straightened it out. Just messing around, any way I put it all back together and plugged it in and the bell starting ringing, lights flashing, the hold buttons lit up for the first time and the top attendant light was flashing. Those never lit up before. I opened the machine door while it was going nuts and the coin hopper was turning like it was stuck on a jack pot pay out.

The monitor was flashing but still didn't have a picture on it. So after letting it do that for about 2 minutes I unplugged the power cord and then plugged it back in and it is back to the way it was,,,,blue snow, no sound, hold lights not lit, attendant light out.

Kind of weird huh? I tested my battery on the board and it reads just under 2 volts. Do you think the battery being low would cause all this, or should the monitor display a screen regardless of the battery volts?

Man, I have read some crazy stories on this site about batteries reviving all sorts of crazy circumstances.  When all else fails...why not?

Anyone have a manual for this or a link to download or view it?  Some guy had a few manuals online for sigma machines but not a model B-9.

I finally got around to replacing the battery on the board today but still have the same problems. Turned the reset key on, powered up but nothing on monitor except blue snow. I did here the speaker 'crack' one time but no picture.

Any ideas?

I have a Sigma B-9 as well as the manual.  How can I help?

[vegasmax]

What does the manual say about doing a reset? Are clear chips needed?

Also there are 5 red LED lights on the bottom board. Some are lit and some are not. Are they for troubleshooting?
