Did i say twist it with your bare hands when it is plugged in?
And it changed in size, sometimes this fixes it, i am just trying to help, dont be a baby about it.
You sure it was not a 220/240 volts screen, modified with a 110/120V plug? try pulling the high voltage plug out and sticking it back in so the pins are sitting horizontaly compared to the screen, !!! watch out even unplugged it can still discharge 10 000 volts.
When unplugged take a hairdryer and blow it in the hole and heat up the tube so any moist can escape trough the hole.
And if you can just exchange it
it could be just moist since the technology is old, the screen may have been sitting on a shelf for years heat and cold could have drawn in moisture over time, an electric charge could make it all sit in one spot.
When working on high voltage make sure you wear leather gloves or rubber with some other type of wintergloves over. and put on some shoes, and never touch the metal or the tube itself.
