Check the plate resistor on the burst tube. The tubes can short and draw too much current and burn the resistor.
If you can get a service manual, there are two test points that you have to ground to turn on (defeat the color killer) the color circuit and the other defeats the color afc so the oscillator can free run. If you don't get floating color bars after grounding the test points I would replace the color crystal first. You may need to go thru a couple if the first one doesn't help.
Don't turn any coils unless absolutely necessary. They can get fragile with age.

Yeah I'm worried those are shot in mine, and I'm not sure how to build a new one to replace them. That's why I am watching his posts like a hawk. His set suffers the same issues as mine. He's indirectly printing me a road map what to tackle next.
