hello,
I'm having this problem with my crt where it clicks and shrinks h-size to about half.
Usually pressing it's sides or bashing it abit fixes it, but now it won't "click" back.

any good ideas how to fix it, i guess it will require me to open it up, but im very scared of that since i recall something about crt's packing some serious voltage on the tube, and requires special handling :/
