Is it possible that someone reversed the ion trap magnet? Sounds silly, but odd things can happen if a teenager gets his hands on Grandpa's old TV and is inspired to "fix" things.
Some ion trap magnets are marked with a little arrow, which should point toward the front of the CRT. Other magnets don't have an arrow, so don't freak if yours lacks one.
You won't hurt anything if you flip the magnet back to front and try sliding it forward and back on the CRT neck, and rotating, in the usual manner for finding the "sweet spot" with maximum brightness. If no improvement, put it back the way you found it and look for other causes.
Just an idea . . .
