Re: No Power

This is the way how to examine where the problem is. Try this monitor with another computer. If still a problem, you have to check that you can see the image on screen by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons (Power on both cpu and monitor), there will be a minor problem. Like me, I can see window image using flashlight and check lamps inside. Some of them were broken. If you cannot see any icon on the screen. I would say that there are some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or dark spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so.

Display not working, power button LED turns on blue for 1 second and won't turn on again

Have you tried checking with another monitor. Meaning that if the second monitor does not come on then the problem is with your computers mother board. But if the monitor other monitor you check it with comes on then of course it is your monitor.

Monitor wont turn on help

Hello there, first thing you should do is to check the power cable.You can do that by changing it with PC power supply cable .It is the same. If it turns to be OK then disconnect the VGA cable from monitor and then try to power monitor on.There should be an activity on front power LED. If the power LED is not showing any light at all, then do not go further the unit is not working .Else the power led should blink a couple of times then a window pop up scrolling on the lcd saying :" no video signal" so the unit is OK ..Hope this helps. Cheers.

My flatron L1710S flat screen will not come out of power saving mode. When I turn on the monitor the power button/light is green for a few seconds, the screen indicated "power saving mode", then...

I switch on my PC, ensuring that all cables, leads and power supplies are connected properly. The tower powers up no problems at all. I switch the screen on, the green led lights up, the screen is completely black. A blue box appears centrally on the screen with the text 'power saving mode'. The green led light turns amber and then the screen just goes black.

Please don't suggest going to control panel, as I can't get that far.

I have the VE278Q which is connected by display port, every time i turn off my computer and then turn it back on the monitor can't be found, I have to unplug the display port cable, unplug the monitor,...

when you say monitor can't be found did you mean the monitor has no reactions when you turn on your pc?

here are some test you may need to do to know which part is faulty
1. Turn on your computer, did it display the monitor's logo on screen? When it does monitor is good, when only blank screen it could be the vga cable or the video card.
2. See if the led indication lit. When it lit to steady green, it's good signal is coming in from the video card. It should be followed by screen display. If no display it could be the backlight inverter lamp busted or faulty inverter board. When lit green then turns red, no signal coming from the video card. Check vga cable if fix properly to both monitor and video card. Or may need to reseat properly connection of video card from the motherboard. If no led indication lamp, then monitor is dead. Check ac power cord for continuity using multitester. Check power supply section in the monitor, replaced bulged or blown capacitor with exact value, this components were the first to get affected when lcd monitor failed o turn on.
3. When computer was turned on got display and then monitor turns black, go check the vga cable, Fix the connection properly or may need to replace it with new one.
4. When no signal appears or display blank screen after logo, then check video card. First remedy is to disconnect it the reseat properly to the motherboard. If this have no effect change your video card.

go follow these steps and let me know which is closely to your problem so I can give you a good advise.

Nothing on the screen at startup

If you cant get into the setup menu then I would think the monitor is defective,you did not state if you hooked up the monitor to a computer that has a vga port that works.

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.

My Lg Monitor wont show screen (Power Button Flashing)

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.

Hi, The part where you see some color bars and blinking green led is what we call MONITOR SELF TEST. A diagnostic pattern consisting of four colors (red, green, blue and white) appears, and the LED flashes slowly. this happens when signal cable from the monitor is disconnected from the tower and leaving the power chord for the monitor plugged in. If the monitor works properly on a different computer. then its a problem with the computer's video card sending out signal. im 85% sure that its a problem with your video card.

Monitor Acer Problem

I agree it isn?t the monitor but I would suspect the video card you are connecting it to or the PC itself. Generally if a monitor doesn?t detect a video signal it will go into hibernation mode, typically displaying a no signal warning and changing the LED color from green to amber. When you start the computer is anything displaying at all? Are you sure the PC is powering up and booting?
