For the tearing try running a weak signal & see if it
gets better. If so look at AGC. If not horz AFC diode area. The UHF is the drive mech. Its replaceable, IIRC just clips in place. Very common fail. Antenna probably is ball & rod clamped in a C shaped mount. You could change the ball & rod or just the rod. Finding the right size is the trick. Keep in mind these sets were built to just run & sell cheap. The parts count is very low & it dont take much to cause trouble. Shows were the name " Good Enough" came from. 73 Zeno  LFOD !

I've got the UHF knobs - both the outer and inner. If you'll post pictures of how the antenna mounts in the back, I can probably make the trifecta - all for postage only.
UHF knobs are ES43X490 (inner) and ES43X491 (outer)
