The fly sounding strained sounds like a more telling lead... if the h osc is too far off the correct frequency then the HV output and sweep will collapse. The entire h output/fly/yoke is a big tuned circuit and needs the right frequency to work. Also the waveform and amplitude need to be at least close to the right for the system to work... when it it right it should be a high pitched whistle tone no screeching or crackling.
Make sure to get a schematic...TVs are complex and diverse so flying blind without a schematic is going to waste more money in burning through your valuable time than buying 10 schematics will cost.

I will certainly try adjusting to see if I can get the flyback to sound somewhat correct. Would the adjustment being off cause no voltage to go through the plunger though? Like I've mentioned before I'm really new to TV's so there's quite a bit of confusion on my end. Dang audio repair is so much easier.
Just ordered the schematic, so that'll help hopefully.
