I've seen this happen a few times with TV's; but, it's usually the horizontal section that does this and it's usually due to bad solder connections at the PC board plug or a loose connection between the yoke plug and the PC board plug. When this happens, I clean up the mess and hardwire the yoke to the chassis.
Once, someone gave me a 20" TV/VCR combo that they took to a shop and they said it couldn't be fixed. It had a hole burnt in the PC board around one of the yoke plug pins. I checked the output components and found them to be good, cleaned up the mess, hardwired the yoke wires to the chassis, and the TV worked fine.
