Dani, thank you very much for the info, however this set has the
trouble on the right of the screen. The picture still seems to be
centered okay, just this trouble at the right-hand edge. It affects
from the middle of the edge to the right corner and is pulled in at
any point along the vertical depending on brightness level in picture
to left of it, leaving unlit pixels.

I will try to do an illustration of it and include it.

Jerry, of course it's more intelligent to find defective parts if any
are, however I got given this set and it had cramped frame affecting
top half of frame, cure was new frame IC and replacement of two high
ESR caps in its feed lines. Also, one O/C dried-up cap was found by
accident which was in circuitry associated with the HT feed to the
line-output transistor - it was a 2.2uF 160V type and was also
replaced. Thing is, I don't know if this problem on the right edge
was always there and the other owners didn't really notice it, as it
isn't that bad, it's just I've got a keen eye and don't like it, or
if it's new. Others have told me before that they don't notice most
picture problems till I point them out.

I have already checked all caps in the line stage and amp area. Those
that had even slightly high ESR were replaced. All others were fine in
ESR and capacitance value. Also checked for any resistors that may
have gone high, none have of those I tested. Also checked all diodes
for any leakage but all read fine.

Here is illustration:
