Monitor shuts down and glows pink

Usually it's a problem related to the Graphic card (expensive) but before replacing it I would try the monitor cable on a different Pc: sometimes it's just a matter of a damaged VGA or Hdmi cable, which is cheap to change

Shine a flashlight on the dark screen to see if you barelysee the icons on the desktop. If so, then the LCD Inverter is bad.

Plug in an external monitor and see if the display shows up on it. It can beany kind of monitor even the old big fat crt monitors as long as it has a vgacable to connect to your computer's vga port. If so that proves yourvideo card is ok. The video will show on most systems when you rebootwithout you having to do anything. Some systems will require you to hit the FN(Function key) + F1 thru F12. Hold down the FN key then hit the correctkey for displaying on the monitor (F1 thru F12). The correct key willnormally have CRT/LCD on it or it will have the icon of a display.

If you see no icons by shinning a flash light and the external monitor works,then your screen is bad. If you see no icons by shinning the flash lightand nothing shows on the external monitor, then most likely your video card isbad.

Is the power scheme on your computer set to turn off the monitor after 5 minutes?

The backlights lamps should stay on even if the LCD panel section is bad. It sounds like you have to check the power supply voltages, caps, inverter circuits. Bad lamps can glow pink instead of white glow.
Please read my guides to uderstand how LCD monitors work.

With your UPS turned off, unplug your PC and all other devices from the unit. Then turn the UPS on. If it still beeps and shuts off your UPS internal battery may need to be replaced or you have an internal UPS failure. Look for a red "battery alarm" light on the front of your UPS.

If the UPS does not shut down with all devices disconnected from it, Power off your monitor and look on the back of the monitor for a label which will tell you the amount of power it requires (probably 100 watts or less). Plug the monitor's AC power cord into your UPS and turn on your PC and monitor. With the UPS plugged into the AC line you are not using the internal battery and the UPS should remain on and your monitor should be working. If it shuts down you have an internal problem with the UPS.

Now unplug your UPS from the AC line (simulating a power failure) Your UPS is rated at 350 watts. Accordingly it should easily support the 100 watt load of your monitor. If the UPS continues to provide power to the monitor for 1 or 2 minutes down it's an indication that it's working properly and the COMBINED LOAD of your monitor. PC etc. when plugged into the UPS is exceeding the 350 watt capacity of the UPS. You will have to disconnect 1 or more devices from the UPS.

NOTE: Never plug a laser printer into an UPS.

If the UPS immeadiately shuts down after disconnecting it from the AC line with only the monitor plugged into it you have a bad battery.

Without any instruments to check it with, substitution is the best test; in other words connect the monitor to another system for a minute or two and/or a different monitor to your system. (If you can do either, don't do 'hot' swaps, turn everything off and then back on again.)

If you've noticed it; you may have seen that the LED flashes if the monitor is left on and the system shut down. Removing the VGA cable from the back of your system (or the monitor if it is separable) should produce the same result; flashing LED. If this is the case, then your video source from the system (on-board of add-on) has failed. If the video chipset on the motherboard has failed, it can be disabled and replaced by an add-in board for a few dollars.

Lcb is liquid crystal display and there is liquid and some chemical in it and it cause this problem .or some put some think on it or you drop the lcd . i also have the same issue . If it is under warrenty replace it.

I suspect the power supply for the monitor. Try a power supply from a working monitor. If you have a used computer store nearby, take your power supply to them and try it on another monitor.

There is no need to turn off a monitor using its power switch. Monitors automatically go into standby mode when they are not receiving a signal. In standby mode they use less than one cent of electricity per day. If saving electricity is your goal, raise the temperature in your home by a degree and run the air conditioning less.

You may be blaming the wrong device. I suggest you try the monitor with another system, the problem you describe could be located in the video output of your system instead of a monitor fault.

It may not be related to room temp, but it sure sounds like there is an internal problem relating to temp. Meaning, there is a component (probably a capacitor) getting over heated or leaking. If this is still covered under the mfg warranty, I would contact them to get it fixed. If not, then taking it to a repair facility that can repair it is probably a good idea.
