Why no love for this GE roundie ?

burnt coil at interlock not good, sometimes opens from bad solder you will just need to check continuity from Power trans back to interlock (which may be bad too, wiggle the plug wire there). I generally will just hook up a meter to the AC plug and check for continuity, switch on, if nothing then just trace until you find where it breaks.

No reason to mess with the CRT until you see what kind of pic it makes.

you need to start looking for a coil at least to replace the broken one.

thermistor is often broken, check across it, cold prob 100 ohms, or turn on set for a few seconds, then off. if its cold you know its bad.

On mine one of the power resistors on that board with the thermistor had been replaced as well (incorrectly of course), so you may want to sweep thru them as well.
