Hi, guys. I'm looking for a functional MK2 pcb with working soundboard. Thank you!

Yes. I've swapped out the board with my UMK3 board and all of the buttons function properly. We originally wired the machine the UMK3 board in there and got the problem as soon as we hooked up the MK2 board. I've disconnected the low punch button on the left side altogether and still have the...

My MK2 board has the left player low punch button perma-stuck and I don't know how to fix it. My sound board works fine, so I just need the main board. Although having a spare sound board probably isn't a terrible thing if you want to sell it as a package.

Hey, guys. I finally got my soundboard working for MK2 after getting the necessary cables. However when I power up the game and go into the dip switch test section, the left low punch is constantly on. Every other button works great except for this one. I've pulled the ground off that low...

Actually I still need help finding this cable.

What's a sound pot?

Nevermind. I see that's a pretty easy to find cable. Thanks again for your help.

Hey, I just now realized what you were talking about. I read your post too quickly the first time around. I didn't realize what you meant until I was on quarterarcade.com contemplating just buying a whole new MK2 pcb. I looked at this picture...

Hey, guys. shatter1 was kind enough to send me the cable I needed to connect the satellite soundboard to my main MK2 board. The red light on the sound board lights up, but I still have no sound. In the sound diagnostics, it tells me "No Sound IRQ detected." Anyone know what's causing this?

Hey, guys. I have an MK2 pcb with a supposedly functional satellite soundboard. The seller unfortunately didn't include the cable I need to connect the two boards together. The technical manual says that I need to use a Molex 9-pin 0.156" header connector for each board's connection. It's...

Thanks for your help, osver.

Hey, guys. I need some help figuring out how to remove my joysticks in preparation to install new ones. I can't figure out how to detach the shaft. I tried unscrewing it, but that doesn't seem to work. I also tried detaching the base on the underside, but that isn't it either. Also, when...

I think you're right. The back of the cabinet says "Konami" on a sticker. The UMK3 marquee did not fit perfectly and you can see that they cut the sides of the original marquee to fill in the blank space. That cutout part is green and made me think of TMNT. So in all likelihood if this is a...

Ok so in the first pic I posted, that green board in the center of picture coming off the back of the monitor - there should be knobs on the other side of that thing that I can adjust? Do I need to get a monitor discharger before I try and do this or can I just unplug the machine and not worry...

Hey, guys. This week I took delivery of a UMK3 machine that I've been waiting to get ahold of for several months. It was purchased off ebay and this is the first arcade machine I've owned. I was able to turn on the machine yesterday, get it to boot up and played a few games. I have a few...
