Gonna finally call this one done after I give the tuner a good cleaning
The screen shot is lousy, but the set regained contrast after I removed ALL the wires from the candohm, and used terminal strips to isolate everything. It looks like a bit of a train wreck, but hey, it works!
It's not *as* contrast-y as my 8TS30, but this set has zero horizontal or vertical lock drift....and mine does a little while it's warming up. I'll just chalk that up to their individual "personalities"
