Plase update Display/graphics driver.
If you have a external monitor try plugging into notebook, if the external monitor works fine, you can replace the display.

>Check in safemode>If its stays for long time, it could be an issue with Virus.
>Check in BIOS as well
>If the external monitor is also acting in a same way, you may have replace the system board

SOURCE: When it's turned on, the light on my monitor blinks but the screen doesn't display anything. Why ....

they normally turn off like this when they aren't receiving a video signal from the pc (same as when you turn off the pc). make sure that it is connected properly, and that the video output is activated. try disconnecting from the other monitor while its on and connect the problem monitor...if it still isn't working then there may be a problem with the cable or the monitor itself. Try another VGA or DVI cable. Hope this helps

SOURCE: aoc lm725 display off after few seconds

I've had a very similar issue on many Dell Monitors. Mine have been under warranty and they usually send me a new monitor, but I believe the issue lies with the power supply within the monitor.

SOURCE: monitor goes dark after a few seconds

change your cables, there might be a problem with them though you may not see until you use a new different one.

if the problem continues, it will be the monitor that has to be serviced.

i would like to hear from you,

thanks,

SOURCE: ACER AL1914 LCD Monitor goes black but green light stays on

The monitor is doing a self test a finding an error.
The lcd has three parts, the screen plate(windows)/the logic(vga)/the inverter(power plug). Parts that go are the backlight ccfl's, behind the plate, and parts of the inverter, ie capacitors, all three take a bit of power from the inverter. The self test check that all the lights are ok and the inverter is ok, else it switchs off, ie if 3/4 light work it will switch off(my own case), hence the on chech error then off, However sometime there are stages of on/off ie on/ but no screen display, if that is the case the following may be of help...if you put bright light at an angle close to lcd can you see a windows shadow, text icons etc, ie still logic power passing,then .... (from a.n. other) after two weeks searching I finally find doctor living stone http://www.aplusperfect.com/articles/lcd_capacitor_repair more fun with paulbtorrent
the takening the case bit off is like opening your wallet a second time after buying a new LCD, but you must! smallest two screw driver's flat headed, practice using two pennies stuck together()with your fingers after, one little () move and inch and {} again, with the case , it does not break, just need to lever open
[once open you realize they somehow put that old briefcase clip inside!] also note the bright light test to do first to see if can see a windows screen , and that capacitors are one for a number of things that a make a inverter work! there a transistors as well, given that however, to replace all the capacitors on my inverter, was 11 capacitors, cost me $11 (uk ebay) and already had the iron and solder. So only cost me me $11 to try and see but no luck , still fun and I still can see the screen for 2 sec' at a time plus I have a spare set of caps now in the event that the new one do go burst! you have to laugh really, what next , a new on/off button, as you work though the whole inverter mmmMMMMmmmMMMMmmmMMMMTim Berners-leeMMMMMmmmmMMMMMmmmmcome back all is not wellMMMMMMMMMMnnnnnnweek later land sight mmmmmMMMMMMMMMmmmmgggggggg(from
another a.n other)Generally, if the screen went out quickly, it was the inverter. If it went out over a slow period of time (flickering etc..) I would bet it is the lamp.replaceing the lamp should be pretty challenging. as that requires complete breakdown of your LCD, extraction of your dead lamp, and soldering in your new lamp... but I would like to say that I it did this after realizing it's 2 x kitchen strips inside [========] with wires that can connect back to the inverter with out any desoldering(ie kit assembly/dis) with the outter case remove (glass plate safe away) I could reconnect and see that 3/4 were working (i!i hardcard ) cause the inverter to switch off after a secound ! order bult and replace and going
to cheap and see if I can get away with fitting a 15" in my 19' as it a 1/3 of the price ! the market as drop out there, hope the inverter does not miss the length, or the screen out put.http://www.lcdparts.net/howto/troubleshooting/LaptopCCFL1.aspx OR MONITOR

The capacitors for the power source are failing. This causes a short burst of power to get to the lamps, but then they cannot hold a charge to continuously power the lamps. You will have to replace the monitor. I suggest checking your warranty status and replacing the monitor.

You might need to change the screen refresh rate. Go do Control Panel> Display> Setting> Advance, choose 60 Hz. In order to make your Monitor able to display, restart the PC, press F8 on the keyboard frequently upon splashing ( 1 or 2 seconds after PC restarts). Select enable VGA mode by pressing up arrow of the keyboard> press enter. The display should look bigger, then you can start adjusting the screen refresh rate to 60 Hz

The monitor displays the screen then goes black. For example, I turn of the monitor off and then back on. I will see the screen for 1/2 second then it will go black.


Hi sglick - you will need to do a few simple trouble shooting steps to pinpoint the problem, as this can be cause by several different things.
Follow these steps and reply back with your findings: 1. Unplug the monitor power cable, wait about 30 seconds, reconnect the cable and then turn on the monitor. This resets the electronics on the monitor. 2. Make sure the monitor has power - the light on the monitor is on. If the light on the monitor is off, the monitor does not have power. Connect it to a different power outlet. 3. If the monitor has a detachable video cable, obtain a second monitor cable for testing purposes in case the cable is bad. 4. Disconnect all connected devices except the mouse, keyboard and monitor. This includes thumb drives and camera-type memory cards from card reader slots. With the devices disconnected, restart the computer. If the computer starts and the monitor now displays a picture, a device is preventing the computer from starting or sending a proper video signal to the monitor. Update the BIOS to resolve this issue.
If doing all of this doesn't change your issue of no video after seeing it pop on, try the monitor on a different computer/laptop, and if you have one, a different monitor on the system with the problem.
Let us know what you find following these steps and we can figure out what to do next. -Trev

Video (picture) must be constantly entering a monitor for a monitor to continue to display a picture after it self tests (goes on for a second or, two) Your monitor is fine; check it using another known good computer.
