I would try and see if the coil can bring it in. Then you would know if it's time to look at the circuit components. It may bring it in just the way it is. Wiggle and move stuff around to see if the osc is stable or jumping around or totally out of wack. And what condition the Horiz pot is in.
I remember trying to get the vert to lock when I was a kid. Stupid TV just keep rolling. Now the stupid TV is so bright it hurts my eyes.
