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

Re: LCD Shuts down
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.

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.
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.
dustcore025, Need a little more info here. Do you know age of monitor? Was it or did it display a "perfect' image on it the day before? Is it under warranty? How far are you willing to go to try and repair this thing? Do you know how to "part" the snap together plastic back cover from the bezel, after removing the pedestal? This sounds to me like a Switch-mode-power-supply or Inverter problem that occurs when some Electrolytic Filter Capacitors get a little bit TIRED of being constantly subjected to high temperatures near heatsinks that are used to keep semiconductors within operating limits. You can determine how bad this may be if you can do a test and remember what happens. Here is what to do. Make sure PC is fully booted displaying WIN desktop or some other screen. Next, with someone to keep hitting the CTRL or SP bar key every 20-40 seconds while you reconnect both cables of your MM17 back to the PC video port and ac outlet. Now try to turn on the monitor and note exactly what you see and for how long. Did it have a sharp clear image, even for 1-2 seconds? did the screen go black? OK! Next thing is to shine a bright flashlight onto the screen 2 inches away from where you know there was something a few seconds ago. Try it at different angles and not if you see anything. get back to me with results of test. I'm louie12fix on fixya or lmistyrel @ aol.com BYE for now.
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.
