Re: HP TCO '03 MONITOR SHUTTING OFF
Did you check the sleep mode or power off
mode? What do you do to make it come back on? Sounds like it might
be getting too hot and/or going bad. Not sure how to diagnose this without seeing it myself. That is the best that I can do. Your video card could be going bad. Try another video card on that monitor. This will be the only way to decide if it is the card or monitor.

The problem is more than likely caused by the flyback transformer, this generates the high voltage to the crt screen, when this part fails the protection circuit activates causing the monitor to shut down.
disconnect all the cables except the power cable and then turn the monitor on you would see a test screen if it still happens your monitor is faulty and better buy a new one as repairing is usually expensive .
caligrl2007, Sorry to hear you are having problem with your monitor. When very strange things start to happen with an LCD monitor, the first place I would look would be the "switch-mode-power-supply" inside of the unit. If unit does same thing when connected to KNOWN GOOD pc, then a technician will need to investigate the SMPS. 12fixlouie
Ok, another words, monitor powers up for few seconds and shuts down by itself. If green LED on the front panel turns off as well or stays on? If stays on, then inverter turns into protection mode because of old backlight lamps. If it turns off in same time with an image on the screen, then there are some bad electrolytic capacitors in the power supply.
I had a similar problem whereas my monitor went to sleep mode after a few minutes. I'm running an HP LP 2065 in dual mode with another HP flat screen. However, I did resolve the issue after resetting the output settings.
How to do that:
right mouse click on the desktop
select graphic options
Maybe some changings/modification will help you too.
you turned it on and the screen shut off, check the image on the screen by
shining a flashlight into the screen, not directly but find the best angle to
the screen and take a look very closely. If you can see the icons or any image,
there will be a minor problem. This is because of the lamps inside screen. Some
of them were broken and it is very easy to replace. If you cannot see anything
on the screen, there'll be some problems with inverter board. If the computer shut down immediately after the monitor shut off, it might be because of fault operating system. Check with another monitor. Thank
