Many years ago I ran into an RCA TV that had a vert osc that wouldn't run. The vert hold control read fine out of circuit, but I missed the part where it had about 100K ohm leakage through the case of the control to ground. When I lifted the vertical hold control off the chassis and let it float in the air, the vertical came back.

Long shot to be sure; in 50 years in consumer electronics I only saw this once.
