How does a CRT end up with a vertical line of dead pixels?

Sylvia.

It processes the signal as digital then converts to analog for the CRT
driver. I'd guess it is not going to be worth trying to fix, something
is gone in the digital section(s).


some chip in the frame memory?

Could it possibly be a stabilising wire as in the Trinitrons(I know they
are usually horizontal)
