Guns N' Roses
Data East, 1994
I've search and not found anyone with this problem previously. Any suggestions on where to start?
I have re-seated all connections and checked all fuses.
It's kinda hard to tell, but it's not just a single line working, the display is squished into one line. I think anyways.
What decodes the rows? Hrmm
I would check out the row clock and row data signal at cn1. maybe replace the ribbon cable if you have one.
this is probably going to be a complex issue to diagnose if it is more than an open circuit caused by bad connectors. Isolate to CPU or Display and work from there.
