Phosphors do lose efficiency but I dont think that is the main
problem. I think mainly the cathode loses emission. This can temporarily be
improved by CRT rejuvinators or raising the heater voltage (I'm old enough to
remember the old cylindrical autotranformer picture tube brightenters that you
stacked on the old B-W TV CRTS: they basically raised the heater voltage a
little bit, squeezing a little more life out of the CRT)
First off --
can somebody explain the common problem with the
monitors going dim? Can I fix it? (How?) Is there an internal
"intensity" pot that I can adjust to get more life out of the
monitor? It is just bright enough not to strain your eyes at
the highest brightness setting right now... (It's B&W)
I have always assumed that the electrons just kick the sh*t
out of the phosphor, and the the phosphor just dies... but I
hope that's wrong, and that something can indeed be adjusted
or replaced (other than the daggone tube itself).
