Either the computer isn't starting up or there's a problem with the video. It's pretty common for a computer to come on when you press the power button, but not actually start running.

Do you hear the sounds that go along with a normal startup? Most computers give a beep when they successfully complete power-on testing (POST). Does this happen? You will usually hear hard drive activity, and on most computers there's an indicator showing disk access. Is the light flashing? Most importantly, do you ever hear the Windows startup sound that means it's up and running? If this is all happening, your computer is working except for the video. On systems with integrated video (that is, built into the motherboard), problems usually are detected at POST time and result in error beep codes, but not always. If you have a separate video card plugged it, it may have failed.

If the computer isn't starting up you'll need to get that problem solved. It may be a power supply or motherboard problem, or problems with any of the parts connected to the motherboard. If you don't feel comfortable working on the computer yourself, there should be servicers available in your area who can check it over and make a repair estimate. Otherwise, disconnect everything from the motherboard except for the power supply, memory and processor, and then try starting the computer. If it starts normally, you'll know the trouble is in one of the disconnected parts, and you can start reconnecting pieces until the problem returns. If the computer still isn't starting with that minimum configuration, the power supply, motherboard or processor itself has failed.

Good luck with the repair, and thanks for using Fixya!

This is an indication that you may need to replace your video card.

Hope this helps. :)

Hello,

It is the picture picture board on your monitor that is malfunctioning, since the power led or button is on, but the display screen goes blank after a fraction of seconds, it means the picture board of your monitor has developed fault.

The best thing for you to do now is to take the monitor to a local repairer within your vicinity or any service center to help with the replacement of the picture board because the fault is not something you can fix yourself, in order not to complicate issues.

Take care.

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??

Flickering switch light, blank screen


Hi, First of all it is not advisable to open up monitors without proper tools as they contain hazardous elements. Dell monitors however do have a 3 year SEPARATE warranty. Check on the back of the monitor and look for the monitor serial number. is should start with CN-xxxxx-,, or JP-XXXXX-. give that to a dell tech and they should be able to replace that.
