Check the caps in the power supply/inverter bd. and on the logic bd. first.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

I turned on the computer and blank monitor screen.


have you checked if monitor cables are properly seated? have you tried a different known good video cable? also try a different outlet for the power supply for the monitor. lastly, try a different monitor and hook it to your tower. if it has a good display, then you should replace monitor, if still it has same issue, thenyou may want to consider changing your videocard.

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??

My monitor went black, and the power switch just flashes.


is your CPU working properly? if that the case, your monitor is in need of a service.
reasons for why a monitor goes blank?
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.

have a nice day.

Dell Monitor goes blank, green light still on.


Have you tried connecting that monitor to another PC. It sounds like you may have a problem with the monitor itself (component failure, heat problem, etc)

Computer monitor goes blank after initial start-up reaches the desktop


Try setting your graphics card output to something simpler like a basic 640x480 resolution 64k colours and see if it still does it... it maybe that you have the resolution/colour depth to high for the monitor to properly handle

if it is stable at the lower setting slowly increase untill you reach a point that you and your monitor are both happy

Green light blinking screen blank


Hi Suzee,

Is the green flashing on the tower or the monitor?

If it is flashing on the monitor, then it might be tht the monitor is not gettign signal from the tower.
To check, disconnect the monitor from the tower and check the monitor. If you get a msg on the screen like no input signal or check video cable, then 99% monitor is fine.

Check for the power supply light at the back of the tower.

Disconnect everything from the computer and then press and hold the power button on the comp for about 30 seconds.

Then connect the cables and check if it is working.
