Well, I tested all of my connections with my DMM and they seemed fine. I then used a cheap oscilloscope and probed the video signal where the yellow wire is soldered to the driver board pin, and I got what looked like a signal.
I then wanted to test with a different display, but I didn't have another LCD and driver board.
So I got an idea...
Why not disconnect the video and ground wires from the driver board and solder them to an RCA cable, and then connect that RCA cable to a CRT?
I gave that a go and, sure enough, the signal seems to be fine.
So it seems like the problem is something to do with the driver board. I reseated the ribbon cable with no success.
Not sure what else to do...
I forgot to mention, I confirmed 5V going to the driver board with my DMM. I also made sure that the video pin on the driver board wasn't loose or disconnected from the board, itself.
