I have a LCD monitor that shuts down after just a few seconds of showing the display. This just started to happen recently and the computer is working fine with another monitor. It will not come back on until I unplug the monitor and hook up again resulting in above again. I suspect that the monitor is fine because it does show the display albeit briefly. I've also tried with another plug and it is the same problem. Any help would be appreciated. Thanks
The monitor screen may be OK, but the monitor electronics are not. YOu state that the comuter works fine with a different monitor. That leaves out the video card. If you reall ywant confirmation of a bad
monitor, Try it on another computer ansdI am willing to bet that it
will again shut off. Take it to a shop for repair or replace it.
Your welcome. I am sorry it went out. Most shops around here charge almost the cost of a new one. Don't pay more that half of what a new one would cost to have it repaired.Your welcome.

Hook a spare monitor to the computer to rule out the video graphics card in the computer, and sub another video cord from the computer to the monitor if possible to check your LG monitor, If the display shuts down and power light changes colour or goes out it is a power supply board, one or more capacitors open causing the power to fail, sometimes the top developes a bulge making it easy to spot.
Hello there.
Seems like electronics pack up but try an old one. disconnect all the data cables from your monitor side(HDMI, DisplayPort, VGA, USB etc.) or computer side if the ones on display are built-in. Leave only the power cable. Unplug the monitor`s power cable. Press the POWER button on the front of the display and keep it pressed for 45 secs. Plug everything back and give it a try.
Good luck.
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.
elainenemeth, Hi, Tell me more! How old is this LCD monitor? Is it out of warranty? Did the "SHUT-DOWN-IMMEDIATE" problem occur without warning? Did the BenQ display a "perfect" image the day before? Did you actually count----1001, 1002----1010 and then it shut down, after pushing the monitor on button. Did you do the "flashlight" test? With monitor connected to a "known-good", fully booted pc with Win Desktop displayed, TURN ON the monitor! Did it display the desktop for 1-2-10 seconds ? What did you see or not see when you pointed the flashlight at different angles about 1-2" inches from the now dark (black) screen? Get back to me with your results. I will offer the best advice possible to you as a consumer/user of LCD/FPD monitor. I'm louie12fix on fixya or lmistyrel @ aol.com Bye for now.
hi there, check your power supply on cpu if theres a tripping off , so if theres then replace power supply. then switch it on again. then let me know what happen nexr..
reagards rated me... thanks
Usually when an LCD display shuts off on it's own this can be a power supply issue. I would say if you checked all the connections you may want to contact the manufacturer. If it is only a few months old then you should be able to get it replaced under warranty.
Also, you may have an auto shut off feature enabled on the display itself. You may want to go through the display's menu to very that this is not the case.
your pc may be set to a resolution that is out of range for the monitor.
Boot into "Safe mode" reset the Display settings to 640 x 480.
reboot into normal mode then change the screen settings to your desired resolution.
Thanks Smith, it is the same problem on another computer, shop or new monitor it is.
