ok.. i have a Mag 810FD monitor. My problem is that when i turn on my computer, log into windows, and open up Internet Explorer, mozzila, or try to explore the hard drive, my screen goes black! i have waited up to 5 minutes and then i figured that i had to TURN OFF the monitor and then turn it back on! i have no idea what happened (this has been hapeing for about 6 months and i just installed a new HD and now its doing the same thing.
A guess and a test:
When you are opening explorer or some other program
you suddenly display a bunch of white on the screen
which causes a surge of power to the flyout transformer.
In this and some other components this surge causes the
monitor to shut off (although power light is still on).
Test this way:
Do not open maximized windows for IE, Mozilla, or Explorer.
Open them 3/4 or 1/2 size.
See if that causes the shut-off.
If not, then this is the problem.
. . . and your monitor on its way out.
CRT monitors have several components which
deteriorate over time - and then die.
Also, it is probably temperature sensitive.
Hot - it will shut off.
Cool - it will not shut off
If the test above works, plan on a new monitor.
Could last weeks or months . . . or days.
You can also turn down the brightness and/or
the contrast. Both affect the power surge which
come from a full page of white.
You may be able just turn down the brightness
and stop the problem (for now).
Please post the results of your tests here.
