Not entirely sure what to look for, however, here's the output of the plate on the sync. Hopefully that helps.

I've also purchased a TV analyst for troubleshooting, seems like a useful tool. WOn't be here for another week

That waveform looks pretty messy and weak...See if sams has a waveform and compare. If your sync pulses are messy you will trigger retrace mid line and other troublesome things like that.
