Monitor visual disply problem........

By low_wh ·
Dear all

I'm curious about the monitor visual display.

When a monitor has been used for a certain period, the visual display becomes purplish or dark blue.

What does this mean and what is/are the contributable causes?

Appreciate your kind reply and possible solution.

Thank you very much.

Color change

by mjd420nova In reply to Monitor visual disply pro ...

Is this effect also accompanied by a loss of
proper focus anywhere on the display??
Usually an transistor that is part of the
electron-gun for a particular color begins to
fail and its capabilites are at first non-
linear and color can be lost in some area
of the display. That is if this is a
Cathode Ray Tube. The final phase of
failure is the loss of that color on the whole
display. A can of freeze spray would locate
the device and replacement would be a snap
for a skilled technician. But far better to
replace the whole unit.
