Phil,
If C960 was bad and didn't correct the problem also replace the regulator 
IC951, Strd3030,
which is most likely leaking and check R954 for open or changed in value, 
(120ohm/30w).
It's between IC951 and C957.
If that corrects the sides from pulling in but not the brightness check D210 
off pin 8 of
the FB for shorted.
Hope this helps
Bill

Thanks, but C460 is a 100mfd@35volts in the Vertical, and is fine. This
seems to be a horiz. deflection or PS issue. I was also told to check
C516 (no value given)but I can't locate that.
Thanks anyway.
