Re: blinking L.E.D. light on dell monitor

Try lowering the screen resolution to 1024x768 and see if it displays on the screen. You will need another monitor (possibly CRT as they do high resolutions) to do this.

First check your monitor light is blinking or not. If it is then--

Check your monitor cable which is connected your CPU. If it is ok then
Open your CPU and unplug *********** board power cable and re-install it.
And also remove RAM and clean with a brush softly and re-install it.

Best of Luck

My Dell E173FP monitor will not come on. I have unplugged and replugged the cable from monitor to hard drive case as well as the a/c power cord. I have rebooted the computer several times and all I get on...

The dreaded blinking green led without a display, means that the backlight circuit has failed on this monitor. Typicalll the transistors that drive the backlight transformers short out and fail. I have fixed this on my monitors twice. Very common failure for this monitor and can be fixed quite easy if you know how to use a soldering iron and a meter. They even sell a repair kit on ebay that provides parts to repair this monitor. Just go to ebay and search e17fpb repair and to find it. Hope this helps.

Dell E173FP Monitor requires unplugging/plugging back in to wake

Perhaps your computer is hibernating instead of going into standby which takes a little longer to wake up from. While you are playing plugs and cables it give it enough time to come out of hibernation.

When the computer is in this mode the USB ports turn off which disables keyboard and mouse so the only way to wake up the computer is to press the power button on the computer itself.

One tell tale sign a computer is in hibernation is that the power light on the computer will slowly blink.

I hope this helps.

Dell e137fp monitor flashing green...

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.

Dell E173FP Screen blinking red, green, blue, white

The monitor is probably on protection.

To start unplug monitor from power and from computer and test computer with different monitor to find out if it is monitor or computer fault.

If it is computer fault and no video signal , then test:

  • Video cable.
  • Video adapter on PC (sometimes integrated on motherboard)
  • Motherboard.

If it is monitor fault , then the monitor is on protection.

When on protection you keep having a flashing led on front of the monitor , and monitor turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the Monitor goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or a broken contact, identified an internal fault and kicked in , starting the flashing light.

If you are in situation one, then the monitor will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, faulty inverter board, faulty input board, or a fault on LCD Digital Controller board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.

Try moving the video cable, and if the cable is not built in, then also try a replacement cable.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

Unplug the cable from your PC, if the monitor shows a test image, the monitor is fine and the problem is with your graphic card. If you dont see nothing on-screen after unpluging the cable from the PC, then the monitor in damaged. Send it to repair.
