I had a spare "untested" cpu brd tried the 5C ,5D & 5E  & 3H chips,  symptoms did not change, even  tried the Z80 chip.  NO help  All these chips look fairly clean.

the dkr1-x chips are really cruddy 

Used dust spray to clean the sockets.

I just cleaned everything again Pencil did the trick!!!

NO change ....

bummer good hints...

I was hoping swapping some IC chips especially 5E would help nope....

Here another screen shot, game is iidle should be just displaying .  ninentdo 1982
I have "e" 's  filling the screen.  should be just blank.

The first screen  pic is displaying I believe  "down-spouts"   filling the screen
The down-spout is on  level 3.

so DKJ chips corrupt?   

Yes I have checked this out along with Mike's arcade repair logs for dkjr,  didn't quite find much on this issue.  Tried some IC chip 5B,C,D on the cpu side, no change in symptoms.

hopefully this worked??

lovely picture...  dd doesnt do much once you start the game, he can move back in forth about it...

Folks,

need some help on possible what may be the issue?   . Game powers up, sounds works fine, noticed that the screen is displaying "pipes" / games plays but DD will just move back & forth. when  he jumps he falls in water  or if you catch a vine, he freezes in motion , until a hits him(hard to explain) background plays fine.  Game worked fine for awhile.    
reseated all IC chips cleaned.
Had a couple broken .01 uf caps on the edges. repaired.   NO change.
DC voltages on p/s measure normal. (5v,-12,12 ect..)  I have a pinout.

screen adjusts fine..  just have what it looks like is a screen full of "plumer pipes"  

any suggestions would  be highly appreciated

I have a PIC , how do you upload it?  when I hit "insert image" nothing happens?

Love to share this beautiful piture!
