try this old post I've had it twice. Had an open winding for pins 2 and 3 of the fly > which feed the vertical circuit, pin 3 thru the horiz. drive transformer.

Put the back on and maybe ½ hour or two hours. I don't know why the heat gun didn't make it collapse. Shut it off let cool on it own and back on you have full deflection again. > > Any one ran into this before? More soldering?
