OK, feeling like a real dummy. I have several tips that say to check c3317 but I can't find it. Anyone know the location on the board? I'm sure that I am overlooking it, but have been over the whole board a dozen times. I only have a partial schematic but I suspect it is near the micro. I have no vertical at the OSD sync pin 27 on the micro, but there is horizontal there. I am suspecting that that indicates that the chip is bad but could use a little more info on the circuit.
