My PC monitor (17 inch glass tube) is about 4 years old and has
been used heavily. I took the cover off to fix a loose connection
because the picture was sometimes jumping.
Inside the circuit board was quite dusty and rather sooty. The
CRT tube and anything neary was very sooty.
----> Is there any merit in cleaning (hoovering or gently wiping)
this dirt? <----
MY THINKING: I figured that the reason why the soot was attracted
to the CRT tube was because the high voltage attracted the soot on
account of the hold being able to hold a charge (or maybe because
the soot was conductive or something like that).
Then I thought maybe the soot was allowing some of the high
voltage on the tube to leak away and that way reduce the picture
quality.
As you can see I have no real idea at all about the facts of this,
so I'm asking you specialists.

PS: I did clean the inside and I reckon picture looks a bit
sharper. But maybe I am completely deluding myself! Or maybe I
leant on one of the sharpness controls while I was cleaning!
