On a GE no UHF is usually the UHF IF link.
Its a cable with RCA jacks on both ends. They
crimped the center wire & would go cold.
Bad news they soldered them in & you gotta be
real carefull you dont rip out the jack when fixing it.
If you dont need UHF best to leave it be.
Bulb if a bayonette type a #47 a good bet. If it
has just folded over wires a #159 or #259. Zenith used
those a lot. If its an orange light it may be an NE-2,
its a neon so has no filament & is soldered in.
The vert has an electrolytic off the cathode of the vert out
tube. Its either in a can or separate sometimes on the
convergence board. Very common on all sets. Dont
forget the tube can be bad even if it tests good.
After that go for caps & off value resistors. The higher
value resistors drift more especially around the size control.
Dont change the disc caps, they almost never go.
When they do they short & burn usually. If any are
cracked change them.
Last in your screenshot it looks like the blue lateral is
way off. Its the copper colored magnet & it moves the
blue side to side as opposed to the up& down of the
clover. Dont pull it in & out, turn it.
