Swapped the entire tuner assembly from a parts chassis with no change whatsoever.
I'm stumped as to where to start. When one wire was unhooked from the tuner and another was (possibly) grounded to the chassis, I had horizontal sweep, and audio of some kind. Now with the wires hooked up properly, and even subbing a different tuner assembly, I've got zero sweep of ANY kind (just a super bright dot, I had to pull it way out of focus and dim it of course), and zero out of the audio.
Thoughts?
