Negative. You do not need a volume pot for MK2.

As for the sound issue. When you say you get a 'beeping noise,' exactly how many do you hear? The number of tones will tell you which rom is bad. 1 tone means everything is ok. 2 tones means the U2 sound rom is bad. 3 tones means the U3 sound rom is bad, etc. Post up a video if you can so we can see and hear what the issue is.

It is just one tone, but it will do it every 45 seconds or so when I first start it up. I will try to get a video up tonight.

One tone means it's ok. Does the LED light up? Sounds like it's resetting. Make sure your ribbon cable is on correctly at both ends, i.e pin 1 of main board to pin 1 of sound board, etc.

Yes, the LED light does light up. I was out of town last night, but I will try and check it tonight.

Alright. I finally got some free time to work on this, and I can say that the problem was that I had e ribbon cable on backwards in the sound board. Flip it around and it worked perfectly!


Now my my issue is that the the player 1 down isn't workin. I tried it on a different switch, but it still didn't work. Any ideas.

touch the wire to ground (preferably one that you know works), does it work?  Yes = switch issue No=follow the wire back to the jamma connector and look for cuts, breaks, etc
