I received this monitor from my work several years ago and it was working perfectly up until a couple of weeks ago.
My monitors are calibrated, and when I do certain things like:
login through remote desktop and then login from the console or
play minecraft and exit the monitor loses it's settings and I run a special program to restore the settings.
Lately my monitor had a pink cast to it that would not go away when I ran the program to restore the calibration. I thought maybe it had lost it's calibration so I did a fresh calibration and that seemed to fix it... for about 20 minutes, then it went pink again. I did another calibration and it seemed to work but after 5 minutes it started flashing between pink and calibrated.
sigh™
I opened it up and it did not appear to have bad electrolytic capacitors but I replaced them anyways. I tested the old caps and all of them were leaky including the large 450v filter cap.
Now it works fine.
