Screen is tilted. High in the left and low in the right. Is there something i need to move on the neck of the crt?

Loosen the clampscrew on the deflection yoke, gently rotate the yoke until the picture is straight (a mirror will help for this), and retighten the clampscrew. Be careful not to come in contact with HV and make sure the yoke remains in the same front-to-back position on the CRT neck.

Good deal. I thought it was the clamp but wasn't positive. Here's a pic of it. phone doesn't take real good pics though.

Hard to tell with that picture. Looks like only the top has a distortion/tilt and the bottom is flat and straight. If that's true, it is probably a circuit adjustment, not yoke tilt. Maybe something associated with pincushion adjustments.

No its just as bad as the top but my pics are no good when it comes to detail.

Most RCA's had bonded (glued on ) yokes so it
may have come unglued.
Also dont loosen the magnets ( farthest back on neck).
It may have a PM held down with a wire tie instead of
adjustable magnets. In any case only mess with the yoke.
If its unglued it takes a different technique........
BTW it also looks to me that the top is NOT a straight line !

I tried rotating it after loosening the screw. whole thing acts like its glued. the top line is a straight line. again, because of the camera, the lighting or white glare distorted it in the image. As for tilt correction, I've never seen them on anything smaller than 32". My Sony 32" & 36" Have tilt correction in the menu. I used to own a 32" RCA with a switch on the back for tilt. This tv has a slant regardless of its location. Nothing changes it.

I had an XL-100 console from about that time with the same sort of picture tilt. If there's masking tape under the tail end of the yoke it could have just fused itself there, barring the presence of a bonded yoke. That's what happened to a set I'm junking, I broke off the plastic where the magnets were to get the yoke to come off.

Finally, not to thread crap, but would anything in which yoke wedges are present use a bonded yoke?

How do you add a tilt correction coil?

No. Almost all in line tubes use wedges to twist the yoke for finale
adjustments. A few early zeniths ( 13gc10 & EFL's) had a
nice mechanical set-up but it fell to cost cutting. Wedges
love to fall out but usually have little effect, I think the yokes
were permanently bent by them.

It was a pleasure to set up one of those Zenith tri-board sets with the extended field length gun, having the setup with the plastic knobs as Zeno mentioned. I found the tv on the street and it looked to have been dropped at some point. Wish all sets had a sure fire quick way to set up tilt and convergence.
