Question about Mitsubishi Diamond Pro 700 Monitor
My 17" Mitsubishi Diamond Pro 710 has suddenly started to go from normal Window XP colors to a soft magenta hue, sort of a faded magenta fog, when clicking the mouse to go to a new screen. It occasionally goes black too. If I turn the monitor off for a few seconds and power back up, the screen returns to its normal strong colors and picture. I've been using a Matrox G450 video board plugged into a Tyan S1590S Trinity MB. Any ideas? Solutions?
It seems your set has a loose conection in the high voltage circuits,in fact by now it should have many loose conections in different areas like the power supply and the horizontal deflection circuits,if you are familiar with tv service you can use the information as the first step to take,some of the loose conections are hard to see even for the trained technician but the one giving you this problem should not be hard to see,if you are not too familiar with tv service be safe and call for assistance from a servicer a least for an estimate.

Your standby power supplies are most likely at fault you should check the low voltage regulators and see if they are functioning they may be defective.

Tips for a great answer:
The screen on your laptop goes black after every few seconds.
It resumes after a mouse-click or after a key-press.
Click on Start --> In search bar, type power options and press Enter.
"Select a power plan" window will be opened.
Click on "Change plan settings" next to "Balanced (recommended)".
In "Turn off the display", select "Never" from the drop-down menu under both the options "On battery" and "Plugged in".
Now click on "Save changes" button.
hope this helps
