I admit it, and I do feel a bit silly, but I had ignored CN9 near the video input because it's unpopulated and I had assumed (<--that word!) it was for interfacing a DVD player which they never used... Lots of pins there that I don't know what they do (after taking a good look today). Pin 6 though, that's a real eye opener. I'll make 2 posts, this one is what my microcontroller makes of the working board. The next post will be what the broken board is doing...
Working board (Ready and *** is my output, *** happens when 1 second passes without anything coming from pin 6):
