    I didn't even move the monitor, just switched the PC off. When I switched it on, the green light disappeared. If I switch the monitor on while the PC (or any other PC I connect the screen to) is off, the green light displays then turns to orange as the powersave kicks in.

    As soon as the PC is turned on, the power light goes off. Turning the monitor on while the PC is on results in a pixely screen refresh and then the power light going out again.

Try your monitor on another computer or another monitor on your PC. This will tell you if the monitor has a problem or your video card (or connection).

Below you will find my recommendations for troubleshooting this issue:

1. Reseat the power cord and verify a good power source.

To reseat the power cord, follow the steps below:

1.1 Power down the system.
1.2 Unplug the power cord.
1.3 Wait approximately one minute.
1.4 Reseat the power cord.
1.5 Verify that the power cord is plugged directly into a known good power outlet.

2. Verify that the monitor is receiving power from a known good outlet and bypass any power strips.

To test the power outlet, perform the following steps:

2.1 Unplug the monitor power cable from the power outlet.
2.2 Plug in a different device, and verify that the device is operational.
2.3 If there is no power try another outlet. Remove any power strips and try plugging directly into the main power outlet.

3. Verify the monitor is powered on and the power button is engaged.

Ensure that the monitor is powered on and that the power button is fully engaged. To do so, check the power LED on the front of the monitor; it should be lit.

NOTE: There are two types of power switches:
A mechanical switch characterized by a long travel. You have to push it further and you will hear an audible click.
An electrical switch that has a short travel and almost no click.

A lit monitor LED can be any of the following:

* Green
* Blinking green
* Yellow
* Blinking yellow
* A combination, such as alternating green and yellow

Any of these states indicate the monitor is receiving power and that you should proceed.

4. Swap power cables.

To try a known good power cable on the monitor, follow the instructions below:

4.1 Turn off a working monitor.
4.2 Unplug the cable from the back of the working monitor, and unplug the cable from the wall.
4.3 Unplug the cable from the monitor in question.
4.4 Plug in the cable that came from the working monitor.

5. Run the monitor self test.

To run the monitor self test, perform the following steps:

5.1 Power off both the computer and the monitor.
5.2 Unplug the video cable from the computer or video card.
5.3 Reseat the power cord to the monitor, ensuring it is plugged into a known-good outlet.
5.4 Power on the monitor.

NOTE: The monitor self test will move around on some monitor models. If the monitor self test moves, allow it to move to the affected areas of the monitor to check for the problem described.

If the Self test failed, it's possible that the monitor is faulty. Contact dell to check if it's still under warranty so they can replace it.

Try unplugging the power cord to your computer tower, click the power button to drain the capacitors in the mother board then plug the power cord back in and try to boot up. Has helped me repair several similar black screen problems. Chuck Housecall101@aol.com

FAST BLINKING GREEN & WON'T POWER ON


I had exactly this problem. After plugging and unplugging it multiple times over several weeks (even plugging it in quickly after it was unplugged but with the green light still flashing as suggested here) all to no avail, it just started working on its own one day. It worked for a few weeks and then the problem re-appeared.

InFocus tech support recommended:
1. Check whether the lamp door is securely closed.
2. Check the color of the LED and the number of time it blinks. (For me, a very fast almost flickering flash)
3. Does the fan operate? (My fan would go on when plugged in)
4. Remove the lamp module, shake it gently and reseat the lamp module.

For me, these steps did not work. InFocus then recommended that I send it to ProjectorDoctor http://online.projectordoctor.com/, and it was diagnosed with a bad power supply. $395, but it is fully functional again. Good luck.........

Monitor won't turn on


Doesn't it turn on even when you boot your computer? Try unplugging the power cord and the cable attached to your video card, plug it in while it is not attached to your computer to see if it encounters the same problem. If so, the monitor might be busted, if not then just reattach and try again...
