Third set in, and I have to say it seems impossible to get a used set that's still in awesome shape, haha. I think I'll be able to sort out most of the geometry problems with this set by twisting the yoke around, though. In fact, I just twisted it to the left a little and it's already a lot better. Now I think it just needs the spacers adjusted a bit to get rid of some of the bowing of the picture up and down on the outer edges.
Adjusting the yoke wedges will only effect convergence. Sounds like
pincushion. Almost sure its in the service menu & you will probably
need the original remote to get in. I dont know how but maybe
someone else does.
BTW those sets are super sensitive to surges / lightning, so unplug
when storms near. We saw tons of these mostly combos with
blown FET's & other damage. On the up side they did throw a
nice pix.

I know what pincushion is, and it's not pincushion. All pincushion adjustments I have seen adjust how far it bows in or out at the sides, where as this is bowing in at the center of the top and bottom of the screen. On my Sony, how it was bending was dependent on how the deflection yoke was 'tipped'.

EDIT: Nevermind, I'm thinking of the parabola adjustment. I haven't seen a pincushion adjustment on a TV, actually, just on computer monitors.
