crt can fail like that.
a crt combines the three primary colors to show you what
you see, it has three color producting systems in the
one glass tube.
if one color unit is about to die because of age, there is
a filament in there which burns out like and incandescent
light bulb, you can see strange colors.
also parts in the tube can get out of allignment and
cause color changes.
also if any electrical connection, either in the monitor
or out, is bad it can do things like that. i have seen
a bad cable connection from the pc or into the monitor
do things like that.
so a couple things need to be checked. you can
tell alot by trying monitor on another computer
or try another cable from pc. |
