True. For a long time I used a 1600x1280 mono Sun
monitor, and it was
a real joy. But years ago it dimmed into unusability, and it looks as
I normally measure hte CRT electrode voltages (and any other voltages I
can think of, like the video amplifer supply, main PSU outputs, etc) in
any old monitor I depend on and write htem down in the back of the
manual, or on the schematic -- that is the values in _my_ monitor
displaying a normal (for that machine) picture.
Then, if it starts to fade, I can re-check them and see if the problem is
the CRT loosing emision or something cheaper to fix like the 1st anode
(g2) voltage going low due to a dead capacitor.
