I know there is about hundreds of threads about DK/DK Jr problems on this forum, I just cant be arsed to look through them all again to see if someone already had the same problem. I hope you guys can point me in the right direction.

As you can see a few sprites has color issues, Donkey kong are not supposed to have green eyes and teeth (even though it looks kind of cool), and Dk Jrs clothes are also supposed to be white and not green.
Regarding the sound there is a quiet "whirring" sound, like a piece of the jump oe deathsound that never cuts off, it just loops in the background all the time... barely noticeable during gameplay but annoying in attract mode.

where to start? I know fuck-all about pcb-fixing but are eager to learn!

(As a side note I have a Double Donkey kong board on the way home so Im not panicing but would like to have this up and running aswell)





If you listen reaaly, and I mean REALLY REALLY careful when I film close to the speaker you can hear the backgroundfuckedupsoundthing... (or is it only in my head)

Thanks, I appreciate it.
Is it. possible to piggyback to test or do I have to go for a swap without piggy-test?
 
Today I found the solution for the Sprite color issue, a faulty HM10422 at 2E on the Video Board.

Just postning it here since I hate when I find threads about problem that dies off without closure.

I am not a repairman, had this on the bench several Times the last year... guess someone skilled would have pinpointed this in under 5min.. :)
 
I didn't realize how old this thread was and was about to recommend checking the proms.
