Sounds like a graphic card driver problem. update your graphic drivers via the manufactors website and download the relivant drivers related to your card. alternatively try down grade your drivers by getting an older version of your cards drivers. either that or boot in safe mode and adjust your screens resolution to a lower amount.

hope this helps

Unplug P.C. remove BIOS battery and and wait a few minutes, replace and connect, boot and see what happens.

More than likely the bios is not switching to your video card, asuming that what you have your moniotr connected too.

Resetting the bios may help.

If not, try removing the video card and connecting to the onboard video, if it has it.

Did it work before and suddenly just start doing this? or is this after you installed something?

Let us know.

Good luck

It switches on for just a second and then the screen stays blank


yetimonsta, Are you sure that the monitor is BLANK?? Or is it just BLACK? Or is it both BLANK and BLACK? Connect a known good monitor to your pc to prove that your pc is working correctly. What does your L90D+ do when connected to good pc. Have you done the flashlight test to evaluate the state of the "switch-mode-power-supply" when lcd panel goes black /blank??

Monitor goes blank


Try restarting the computer in Safe Mode and then check. In case it flickers in Safe Mode too, then the LCD screen might be damaged and you might need to replace it.

Lg w1934-bn blank screen after start up, power light on . same problem occurs on different computers used.


Reason 1: Wetness The number one reason why computer monitors go blank is - wetness. Believe it or not, when your computer monitor is exposed to humid air, sometimes water can condense and accumulate in the monitor. This causes the monitor to malfunction and go blank. I've had this happen to my desktop PC at least three times before. What you need to do is to leave the monitor alone for some time and allow the water to evaporate. That usually solves the problem.

Reason 2: Faulty Graphics Card The next reason why your computer monitor goes black is due to a faulty graphics card. The best way to detect this kind of problem is to connect up a new monitor to your PC, then check if you have a blank screen. If you continue to have a blank screen, then it's likely your video card is faulty.

Reason 3: Faulty RAM This one is less obvious and less common, but it can happen. You might sometimes get bad RAM modules which prevent your PC from booting up even to the basic BIOS startup screen. To detect this kind of problem is more troublesome, you might need to remove those RAM modules and insert them into another computer.

Reason 4: Loose Connections Another reason why your monitor goes blank is due to loose connections. The connection from the monitor to the mains is usually a culprit, as is the connection between the monitor and the video card. Check those connections before you declare your computer monitor as faulty.

Reason 5: A Short Circuit In The Motherboard And the final reason why your computer monitor goes blank? It's possibly because of a short circuit in the motherboard. This is the most undesirable outcome of course, as you might have to replace your entire motherboard. However, it's possible that this can happen - so keep your fingers crossed and hope it doesn't happen to you.
i think this will help.
please rate my solution.
have a nice day.
