Anybody know what the issue here is? Board sustained about a 6" drop. No a major impact by any means, but the only potential catalyst.

Prior to the drop, was working fine.

On first power up, it booted working but with no sound. I then examined the board, applied gentle pressure to all socketed chips to make sure they are fully seated. Powering it up after that, this is what I'm getting.

The cab is good, have tested multiple boards in it, and they are all working fine. This board, not so much. The lines on the screen just keep rolling upward. It does not play blind, this is all I get.

Any thoughts?

 
Found the problem...or at least A problem. 2 cut traces on the face of the b board, below the b-to-c board connector with g/h pins on it. The traces go to g17 and h17 which are not exposed, so will have to find a way to cleanly jumper them to their intended destinations.
 
Yesterday's tragedy is today's success. Jumpered the two lines that had apparently been severed.

Here they are on the board. It looks like a 3rd line got cut, but miraculously it is still operational.


And, board successfully running once again. Now to stop making more work for myself...I already have too many projects as it is.
 
are you hoarding these boards or something? you seem to have a new project SF2 every day. LOL

bravo on the fix though. I love those puzzling games where you can't find what's wrong and the simple solution is sitting right in front of you, staring at you.
 
Heh, I don't think I'm hoarding. This hyper board is my daily player. I converted it to champion edition briefly but have decided to keep it hyper.

Other than that I've got 2 working ww 910214 boards which have been left in my custody but I don't think the owner is ever coming back for them.

In the non working pile I've got 3 complete ww sets, one parts cps dash A board and one ww b/c set.

Okay, maybe I'm hoarding a little... [emoji14]
