Hey folks.

A bit of a head scratcher for me.

WCS 94, after repairing the high power section of the DMD board to fix no display, now seeing what the pics show. Vertical Lines on the DMD. Display test gives the error at the end, PAGE ERROR B (1) 0 15

Same error with the old MPU, and same error with a Rotten Dog MPU.

Display and DMD board both test fine in other machines.

I assume a chip is bad?

Thanks in advance, and any help is very much appreciated.

Fixed. Bad ribbon cable. Doggy soccer lives!

Awesome. Is this the ribbon cable you reseated? If it is and the problem comes back, then you'll want to replace it soon. ribbon cable to reseat (resized).png

Yup. It was that cable. Stole a working one from another game just to test.

Ironically, I also had the same issue on my T2. Reseated and eventually just replaced the ribbon cables and the problem went away. So I can also confirm this is a solid/simple solution to what appears to be a complex problem. Thanks for sharing.
