Mortal Kombat 2 - locks up - weird alarm noise - static on screen - mk2
So, I got an mk2 cabinet a while back, played fine but needed new sticks.
Finally I got to replacing the second stick today but while I was in there I figure I'd flip dip switch 2 - 2 3 & 4 for free play and replace the battery since it seemed to need one. Now I read somewhere I could just use any motherboard 3V battery and it would be fine so I took one from an old motherboard (even though it was smaller) and placed it in.
Now stupid me for making 3 changes all at once. New sticks, new battery, dipswitch changes.
When I fired it up, it seemed fine... it went right into play mode when I hit player 1, but then it locked up and if you got close to the speaker you hear a very slight tone that alternates high - low - high - low - high - low.
I immediately figure the battery is incompatible and take it out, plug the old one back in. I made sure to ground myself so I'm confident I didn't zap something. I fire it back up and it's doing the same thing. If I let it run the ROM tests, everything comes up green. It just locks up, screen gets fuzzy and that's it. :/ I was able to get it in test mode to make sure all the buttons are working. The player 1 coin was acting funny... it was getting jammed, so I thought maybe that was freaking something out, so I disconnected the wires to it (I think) to see if something was shorting out.
I don't know. I'm kind of stuck. Is there anything you guys could point me to to troubleshoot this. I'm really new to this kinda stuff.
