    I have the same problem, do you get sound as I do?

  • jeandunning Jun 02, 2008

    My screen goes blank but if I switch on and off a few times, it comes back - eventuall to stay, but it often disappears 8 or 10 times before I can get it to stay the rest of the evening. The sound is fine.

This is the way how to examine what's wrong with your LCD monitors. After you turned it on and the screen went blank, you have to check that if you can see the image on the screen or not by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons or any image, there will be a minor problem. This is because of the lamps inside screen. Some of them were broken and it is very easy to replace. If you cannot see anything on the screen, there'll be some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or burn spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so. Hope this help!! If anything I can help you with, feel free to let me know.
Thank you,

I have a dell inspiron laptop, and a dell monitor hooked up to it, i turn on the monitor and it is very bright for about half a second then it becomes very dark, so dark that it looks like it turned off,...


Does the fault appear on the laptop screen aswell? It appears by your description that the fault is only on the external monitor. If the screen comes on for a moment and then goes blank as described, then this appears to be an invertor fault. It is very common among laptop and tft screens and requires the invertor inside the panel to be replaced / repaired. Simply plug the screen into another computer to confirm.

Monitor comes on for a split second , and then off


Most common failure in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, 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 Dell monitors to get some ideas what goes wrong: http://s807.photobucket.com/home/budm/allalbums

Monitor does not hold picture screen comes on for a moment than goes blank computor working ok


Try booting your computer in 'SAFE MODE': if it works, look at your Video adapter property and ensure that you have the correct driver installed and that you are not trying to use a resolution greater than your 'default plug and play' monitor can handled. I always recommend starting with 800 X 600 with default frequeny or 50/60hz as it is supported my most current PCs or Laptops.
Hope it helps. Let me know how you go.

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.

Screens works for 5 mins then goes blank!!!!!


It could also be that the video card is not compatible with this monitor. After the pc boots up, can you get into windows? Does the monitor always go out at a specific time on boot? Say for example; you boot the pc, windows startup splash screen comes on; screen does a quick flash and goes blank. Then it maybe the BIOS setting for the video. Try changing the IRQ setting. You could also try putting the video card in another slot. Do you have the manual for the motherboard? Ray

Monitor goes blank


Well, I do not think that there is an actual solution for that problem. I had that exact problem and I had to throw mine away. Turn it in to where you bought it and see if they can repair it. Otherwise they will have to replace it.
