Hey guys, it's been a while but I'm back in the hobby. I've got no power to my PCB or monitor in my MKII cab. The fuses in the iso are both good, but I've got no power going to the power switcher. Dead iso transformer? What should I check and and do next? This is one issue I've never...

My MKII machine went black a couple months ago. There was power to the monitor, but none to the pcb. I finally have time to work on it and was surprised when it powered up. However, it gave me 10 code tones, then made a horrible screech out of the speakers. I thought no big deal since that...

Identify this problem! Buttons work, but aren't working? I switched out the UG12 and UJ12 roms on my MKII board. I took out the challenger chipset and replaced them with the original chipset that came with it. Now, the buttons don't work! They are hooked up and working fine because they work...

I've got a Mortal Kombat board set but no wiring harness from the sound board to main board. It does have the ribbon cable. What all do I need to wire it for sound and where can I get them? If I have to make the harnesses, what will I need to make? It's in an MKII cabinet, but the MKII...

I have a PCB coming in as well as an upgrade chipset. This will be my first time replacing/installing chips. What special tools will I need? Do I have to do any soldering or do they simply "snap" in? Are there any good write-ups on this? Any help or tips greatly appreciated!

I know this is an easy question, but I'm still learning. I've got an MKII cabinet that has been converted to play MK3. I'm looking to restore it back to play MKII. Do I need to get a new soundboard as well as the main PCB, or will an MKII board run with my current soundboard? Also, what is a...

Just scored my first game, a Mortal Kombat 3 in an MK II cabinet. I got it to restore it back to play MK II. I've cleaned it up, and was pleased to find the original CPO in perfect condition underneath the MK3 stick on. It's in great condtion and I couldn't be happier! The problem is 4 of...
