Weird combo... I know.

But I finally built my Stern/Konami adapter tonight and tested out my Super Cobra boards... Only to find they have some of the same graphics issue as my Crazy Kong board.

There has to be a common cause to an issue like this.

And the text/graphics in CrazyKong are the same way:

(Ignore the rest of the issues if you want, I've got attract mode working with CK, still missing graphics... More concerned about the lines through everything).
 
Common cause = 2 dead boards.

I'd check the video ROMs first , since the bad lines in the text on SC are all at the same bit... could be the shifters down the line though...

Hmmmm... just figured that there would be a common cause, figured all that stuff would be handled roughly the same way on the boards... same era, etc etc.

Oh well... might be a little out of my league with these problems... guess I'll start printing out schematics and datasheets and just start hope'ng for something to stick out.

Thanks anywhos.
 
Try reseating all socketed chips (and cables) and re-adjust +5V before diving deeper into the problem.
