The self test thinks nothing is connected to it
it might be the cable or the input circuit.
not an easy issue to verify if you only have one input.
most often its is the internal board with a failed input circuit.
you can only open the unit and test the vga cable continuity.
as most have a 1 year warranty you might want to check on yours.

My monitor is blank it just keeps saying self check its a dell flat screen


Hi,


If it shows "Self test feature check" the cable (VGA / DVi ) is unlplugged on the computer/ tower. Check the cables it may be loose. If not, try replacing the VGA/DVi cables. The LCD is good since it was able to display the self test feature check.

Hope this helps.

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.

Your monitor provides a self-test feature that allows you to check whether your monitor is functioning properly. If your monitor and computer are properly connected but the monitor screen remains dark, run the monitor self-test by performing the following steps:
  1. Turn off both your computer and monitor.
  2. Unplug the video cable from the back of the computer. To ensure proper Self-Test operation, remove both Digital (white connector) and the Analog(blue connector) cables from the back of computer.
  3. Turn on the monitor.
    The floating 'Dell Self-test Feature Check' dialog box should appear on-screen on a black background if the monitor cannot sense a video signal and is working correctly. While in self-test mode, the power LED remains green. Also, depending upon the selected input, one of the dialogs shown below will continuously scroll through the screen.
    1. This box also appears during normal system operation if the video cable becomes disconnected or damaged.
    2. Turn off your monitor and reconnect the video cable, then turn on both your computer and the monitor.
    If your monitor screen remains blank after you use the previous procedure, check your video controller and computer system; your monitor is functioning properly.

My samsung lcd monitor is very dark and can't be adjusted


Hi strat1971,

So the monitor buttons don't work also right? Yeah, normally you should try to adjust the brightness control first on the monitor. If that doesn't work next step would be ofcourse to check the cabling of the monitor to the computer. Try reseating the video cable from the back of the computer. If no go, then the next step is running the monitor self-test. You can do this by just disconnecting the video cable from the back of the computer, and leaving the monitor plugged into the power outlet.

All monitors has a form of self-test that it does to check the functionality, usually a picture or a color bar display on the screen or even a message that the monitor is on self-test. If it's still dim on that screen, then sadly you already have a hardware problem that may require to you buy a new monitor.

Hope this helps!

Peace! :)
