Monitor wont power off


The blue light probably simply means that the computer is not turned on, but the monitor is. Just turn off the monitor, and the blue light should go away.

AL 1706 troubleshouting monitor wont turn on green


If your monitor shows a yellow light and it won't turn green, the problem most likely lies with the computer. If your computer is not sending a signal to the monitor, then you have a computer problem. One way to test this is to turn the monitor off and the computer off, too.
Turn the monitor on and if it is working, it should display a message telling you that there is no signal. If you see that message, you can assume the monitor is working. If you do see it, now turn on the computer and see if the message changes.
If you turn the monitor on and you get no message, you can assume the problem lies with the monitor itself.
If you have access to another monitor, hook that one up to test the computer output.

You can now either get the monitor fixed or the computer fixed, depending on which one is bad.

Monitor wont come out of sleep mode


One possiblility will be the failing power supply due to bad caps (leaking/bulging tops). You can take a look inside first before making the decison to buy a new one or not.

Dell computer monitor wont come on when I turn


When you turn on most dell monitors they come on with a yellow light, then turn green when the monitor and video source synch. If your light is not turning from yellow to green, your monitor is either dead or not getting a signal from the video source it's plugged into. Verify in your BIOS settings that you have selected to output video through an installed card and not from the motherboard source. If the BIOS settings are correct, your monitor has died. If the light is turning green after you turn the computer on, press the menu button on the monitor and adjust the brightness/contrast until you have a picture. If you don't see anything when the menu button is pressed, then again your monitor is likely dead.

Monitor times out and wont come back on.


Try this settings:
  • Click on Start | Control Panel | Power Options.
  • In the Power Option properties window, click on the Power Schemes Tab
  • Set the Turn off Monitor/ Turn off Hard Disks option when on Power (and also Battery for laptop users) to Never.
  • Now click on the Save as... button and assign a name to this power scheme... Let us call it 'Presentation' and then click on OK.
  • That's it congrats!

    My screen wont turn on


    Hiya, have you tried plugging in an external monitor to the Blue VGA port of the laptop ?

    If so, do you get any display then ?

    Hint : you need to plug in the external display 1st, then turn on the laptop. If the External monitor doesn't come on, then you may need to press the Function key on the laptop & the F4 key (Or whichever shows a monitor logo) to get the laptop to switch to external monitor.

    If you CAN get display on the external monitor then the problem could either be that the Invertor for your laptop screen has blown, or, the backlight for your Laptop Screen has broken, or the Laptop screen itself has gone faulty. In rare cases, the cable from the Laptop Motherboard to the screen may be faulty or have come away form the connector on either end.

    Hope this helps.

    Connect another external working monitor to the computer, if the other works then get lamps and inverter replaced.
