Got my monitor issues fixed, and DK is working now with one exception. When you clear the first barrel board, your score (no matter what it was) jumps to 804K. Weird. Any idea what needs to be swapped out? Oh, I should also point out this happened 4 games in a row, but then it didnt happen on 2 other games. In the middle of one of the games that it did happen, as soon as the 1st girder level was cleared, it jumped down to 622K.
 
I should also mention in the beginning when DK is bringing the chick up the ladder to the top of level 1, and he bounces to the left, the ladder stays in "broken" pieces. I'll see if I can get a pic of it.
 
Good luck
First time I ever heard of a score problem on a PCB (except when I was 15 I tilted Space Invaders and a high score came up at 77340)

Nope, no spare boards, and yes shipping would be a nightmare :(

I would first suspect maybe a corrupt CPU eprom in the 5x row.
Then I might suspect a CPU RAM failure or intermittent failure.
If you can, borrow a DK HS kit, it will test the CPU RAM and also
the on kit eprom bypasses the board CPU 5x eproms. Then see
if it still does the same thing. If you have not already reseated
the 5x eproms, do that while cleaning the pins at the same time.
