Title: Looking for UMK3 Schematic
Post by: GuinnessGuy74 on October 12, 2005, 12:34:00 am
Anyone have a schematic for Mortal Kombat 3 or Ultimate MK3?? I am NOT looking for a wiring diagram....I am looking for a schematic for the board.

I have replaced a resistor that was broken off, and it came off again......now the graphics are all messed up. Figure ok, no problem....last time I replaced the resistor, presto, graphics were perfect. Not now. I cant seem to fix the problem.

Anyone who has a schematic or knows anything about these boards, the help would be greatly appreciated!!

Thanks,
Jim

I have a UMK3 in my basement... I'd have to dig up the manuals, but I'm not sure I have the full schematic.

I do, however, have the board.  What are you looking for?

Thanks for the reply!

I am looking for a schematic that shows where Resistor 167 goes to and from. I am getting the same voltage reading on both sides ( a voltage drop of zero) which indicates a short. The traces on the board are very small, so they are hard to follow. I am not even sure what the voltage should be....that would be something very helpful!

The pad for the resistor (surface mount) is now gone, but I am able to solder it to a point right before the pad to make the connectiion. This is how it was so I know it works. But after it fell off this time, putting it back doen't work. I need to know if the pad has any other traces going to/from (maybe on another layer inside the board?). Anyway, if you have a schematic I would love to take a look at it.........


Thanks for the help!

Jim

I just pulled out my manual from that board and there is not a full schematic in the manual.

Sorry... :(
