Default restoring antique tv

well, this is yet, another follow up.

ive been trying to restore an emerson model 663B.

ok, i found out the weakness of the picture was teh ion trap being on wrong.


the picture is now bright sharp and crisp.

everything works now, except for 2 problems. the horizontal is VERY touchy,
and teh sound is weak, but i think i know whats wrong with the sound.

here is what i want to try to solve.

i got the set to work fine, but the horizontal wouldnt lock when turning the
hold control.

i went to the back and adjusted teh horiz. freq. adjustment and it showed up
as multiple images on teh screen, and i adjusted the hold control to get teh
picture to lock into place. but here comes the problem:

the control is very touchy, you have to have it dead on to lock. and the
main problem is, lets say its on a scene from a program, and the picture is
locked in place. well, if the scene changes, like if it gets darker or
brighter, or if the scene moves, BAM. the horizontal is out again.

i readjust and get it to lock, and when the scene changes back, its gone
again.....

but if i leave teh lock alone, it will lose horizontal, and when it comes to
a scene similar to the one i adjusted it on, it slows down to a stop and
locks again, until the brightness, or the scene changes in any way, and the
horizontal jumps all over the place.

I dont have any trouble with the vertical, its as stable as can be, altho,
there are retrace and forground dashed lines that change at different scenes
that drive me nuts, but ive heard thats from too strong of signal.

Any ideas?
