Hi. When I turn my computer on the screen says "Monitor going to sleep" and I can't do anything but look at a black screen. I don't know how to fix this can you help? (I'm on a different computer right now.)

Hi,
I assume this is a Desktop computer:
The Monitor receives, graphics or text from the PC (personal computer) and displays it on the screen.of the Monitor.
If you see a message on the screen that says * NO SIGNAL * in most cases the Monitor is good, and the Monitor is either not connected to the PC or there is a problem with the PC Check the connections and the video card.
The problem could also be related a failure of the motherboard, memory or the processor

Let us know..

If you turn the monitor on with no video cable attached you should get a message on the monitor "Going to Sleep" or "No Signal" if you don't get anything like this the monitor is probably bad. If you can see a message and it is very faint it is an inverter or back light, usually the first in the monitor that is bad.

They usually go off when the don't detect a signal from the computer, make sure the connection is ok between them.

Your computer is in sleep mode, a low power mode that conserves power by turning off the screen and hard drive.

Push the power button on the system and the computer will resume.

If you don't like this feature, you can turn off sleep mode in the power options in Control Panel

If the computer is turning on but the monitor is not getting a signal it sounds like your video card is bad. Fairly easy and inexpensive fix. If you could supply the make and model of your computer I could let you know the card you need and supply installation instructions.

trixieb1, It's NOT going to sleep mode. Use warranty if possible!! If that not option you will need to read about "cold-cathode-fluorescent-lamps" and the voltage inverters that power them. Learn to do flashlight test when screen goes to black or blank n black!!! Read my fixya profile and those of other ccfl back-lit lcd monitor technicians. We already know what is wrong with your unit. And It is a VERY big problem for all LCD monitor manufacturers. Just do some reading before you do anything else. Good luck with the repair. 12fixlouie

I FIX LOTS OF COMPUTER, AND MY ADVISE IS. IT MIGHT BE YOUR COMPUTERS VIDEO CARD CAUSING THAT PROBLEM . ALSO CHECK FOR VIRUSES THEY CAN DO STRANGE THINGS.

You must go into the BIOS of you computer and turn off the sleep mode and also in windows. Disconnect the monitor and power it on without hooking it up to the computer. If the monitor turn on and is working , then hook it up to the computer and try with with the sleep controls off to see if it works correctly.If this works you must check the owners manuals of the motherboard and monitor for the correct operation of the sleep mode functions.Then reinstall the sleep mode operation and see if everything works correctly. If the monitor fails to work. Try the monitor on another computer and see if it will function. If all this fails to get the monitor working , then you will need to have the monitor tested in a service center to find the problem and have it repaired. You should also check your computer on another monitor just to maker sure you don not have a problem with the computer too. Hope this helps you with your problem.

Hi, I used to repair a monitor from Dell. You might have to check what wrong with your monitor when it went back 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 like broken lamps and it is very easy to replace. But the most important part is you need to know how to teardown the screen. . 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 you to examine your monitor. If there is anything I can help you with, feel free to let me know.
Thank you,

This is the way how to check what's wrong with your monitors. After you turned it on and the screen went black, 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!!
