Does it work as a stand alone monitor (single display)?
If not, it may have the problem in the power supply/inverter board.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses; poor solder joints, 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 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.

    The resolution on the PC is set to be the same as the LAPTOP to drive this monitor?

    Other monitor does the same when hook up to the PC?

    It sounds like the setup problem in the PC.

    Took out the nVidia card that had two "waffle" DPI slots and plugged both monitors into the monther board default DPI and VGA slots and everything is working. Had to be something with either the nVidia card, drivers there, or the VGA tp DPI converter. My video is just fine for my use - so I guess I go without the card.
    Thanks for all of your help.

Element tv problems hook to computer get no signal


I'm assuming you are using this as an only monitor for the PC...
What resolution is the screen (max) and what are you trying to put into it? If the video output of the PC is too much it won't 'see' it sometimes... try lowering the PC resolution to that of the screen.

If it's a second monitor, you have to go into the screen settings on the PC and tell it to either 'mirror' (or duplicate) the existing monitor on it or extend the screen on another monitor.

Sorry I can't be more specific as I don't know what the screen or PC (computer) is...

My lenovo Y510 ideapad turns on but the screen remains black. All of the buttons light up, but the screen stays like it is in sleep mode. I have tried rebooting, removing the battery but nothing seems to...


The next tim eit is turned on, try shiniing a bright flashlight directly on the screen.

If you can see anything there then the backlight has burned out on the screen, and will need to be replaced.

If you cant see anything, try hooking up an external monitor to the laptop, if you have a desktop the monitor for it will work for the test..

If the external monitor you hook up will work, then you will have to replace the screen..

( or at a minimum the inverter board, or check that the cables are tight that go to the screen)

Monitor says it is going to sleep and there is only a black screen.


Monitors go to sleep when there is no computer activity it detected. Also, when your OS is working and somehow you have set a "sleep" time, then the monitor goes to sleep at the appointed time. Just press ENTER or press the POWER BUTTON to bring it back to life without losing your computer work.

When screen comes out of screensaver/sleep mode,


It's a bad LCD screen or bad video card. If its a laptop, try to hook an external monitor to the video port in the back and see if it has the same problem. If it is the same problem, then you know its the video card and not the monitor screen. If you have a desktop PC that has this problem, its most likely the video card. First try removing the monitor and trying it on another computer to see if the monitor is bad. If not, then remove and replace your video card and restart. If same problem, replace video card with a new one.

Can't switch on monitor screen


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.

When the computer is turned on the monitor goes to sleep mode


Go to safe mode,select boot in vga mode.

If this allows you to start,

Click start,Run type desk.cpl
Screen Saver tab | click on Energy
Under desk or office settings frame, set all values to "never".
Then click
Advanced Options, you'll see a frame asking you what to do.
Just select the options to turn off sleep mode.
check that out.

If you can't start this way,you need to try another monitor to change the setting above.

Sleep mode


Does the monitor go to sleep when you unplug the video cable? If so, then the computer is still sending a signal, if not, check the monitor menu settings for no signal settings.
