So the clamp and screw on the back of the tube where it’s the skinny part of the neck is correct for rotating the yoke? I could swear the other TVs/monitors I have adjusted had them near the top of the tube where it’s much thicker. Then again none of them were Sony.
I also put the rubber wedges back in. I guess it was a good opportunity to replace the foam adhesive tape.

I decided to walk away for a few hours and just took another look and I did just notice there is a small clamp on the end of the tube neck that could be loosened up, but before I do that I was wondering if that is what it’s intended for to hold the yoke in place against the rubber wedges? I don’t want to have to adjust the convergence so I haven’t loosed it yet just Incase that is wrong. I’m also worried because the neck is the most fragile part of the tube and don’t want to break it.
