increase due which the electrons will strike the screen with a greater
speed.

And your point is?

WTF does that have to do with this newsgroup anyway?

You can't easily "repair" a CRT at home, though I do remember those CRT
"boosters" from the days of B&W TV. They were little autotransformers
which increased the CRT filament voltage a bit to raise the emission of
a partially depleted cathode.
