Blinking green power light and monitor doesn't work

When I came back to work Monday my computer was off and the monitor too. After switching it back on my monitor power light keeps blinking green but it doesn't work. I have switched out the cables and still the same. Has anyone else had this happen?

    I would turn the computer on the monitor would turn on for a second, then reset multiple times and then shut off with the green light just blinking, i would then try various different combinations of turning the monitor off, and on, and cutting the power to the monitor completely, it sometimes fixes it, sometimes not,

I recently had the same problem occur on my LCD Panel and this is the response I received from ACER.

Thank you for contacting Acer America. I apologize for the inconvenience that you have experienced. If the green power on LED blinks rapidly, it means that the monitor is not getting any signal from the computer. It is possible that the monitor may have faulty internal component, I suggest that you send your monitor to a local repair shop to have it tested properly.

Respectfully,
Acer America

Hey, it might be multiple things, first thing, check you db 9 pin connector, the VGA connector for bent or damaged pins, basicaly, unplug the mon cable form the back and check the connector and the port on the pc...It might also be the monitor problem, if you can take your monitor to another pc or laptop and connect, then test it, if problem stays with you pc, then you have a bad system board, or video card, if problem follows your monitor, then replace the mon and get it fixed...

My dell gx260 ligth come green if i turn it on but for a few mins time it turn orange why


Do you mean the monitor's power light starts green and then turns orange when you turn it on? Most monitors will go to a power saving mode when they do not get a signal from the computer.

The Dell GX260 has a green power light when on. When the computer is off, the light is off. If it is green and blinking, then the computer is in a power saving mode.

Diagnosis: start with the obvious: is the monitor cable plugged into both the computer and the monitor (if not permanently connected to the monitor)? Are you connected to the active port? (You can add a video graphics card in most desktops. The motherboard video port usually needs to be disabled to use the card ports. If you plug in the monitor cable to the disabled port, it won't work.) Is the monitor set to the correct input? (This applies if the monitor has several ports. In that case, there will be a Source or Input button on the monitor.) Is the computer on? The GX260 has the power button on the front. (Other computers have the power button on the top.) There is also the power supply switch on the back which needs to be on.

Next try a different data cable between the monitor and the computer (if you can). Try a different monitor. If a second monitor works, than the monitor has a damaged main board. If the second monitor doesn't work, then the video graphics adapter has probably failed. Replace the add-on card, if in use, then boot in the safe mode to remove the old graphics driver. Then install the correct driver for the graphics adapter.

Note: the computer and the monitor should both be off when you connect the cables. Then turn on the monitor first and set it to the correct source before turning on the computer.)

I hope this helps.

After a storm the other night my Proview PL866s amber light is blinking - however when I press the amber button (which usually turns green and then it works) nothing is happening except blank screen and...


If this happened after a storm, the monitor may have been subjected to a power surge, which unfortunately might have killed it.

If you have another monitor (or a friend who has one) try plugging that other monitor into your computer. If the second monitor works, yours will need to be replaced as the input was probably destroyed by the power surge.

If the second monitor also doesn't work, there may be a problem with your computer, most likely with the power supply (this is the part most often damaged by a power surge). You may want to have it examined by a professional computer repair person at that point.

Hope this is helpful!

My monitor screen is black and the yellow standby light is blinking. I can not get the light to stop blinking or get the monitor to show anything, but a black screen. What can I do to coerrect the problem?


mcdevito75 here, Press the SHIFT key, a screen should come up telling you too click on your user name, left lower side of screen. If this doesn"t work, press the yellow blinking light on the monitor see if picture comes back, then follow the directions. If this doesn"t work, shut computer down with switch on the computer itself. Hope this helps.

Monitor black but power light blink green


The 470uF 25 Volts capacitors on the power supply board are probably bad. Replace them all and tell us the result !

Flashing green power light - Black screen


I had the same problem with an AOPEN 17' lcd that was left behind at a rental property... I plugged it into my dell dimmension 4400 in place of my old analog. It worked fine the fist night, and got up and when turned it on again it had the famed green blinking power light. I switched back to the analog, and just disappointed I plugged in the AOPEN to another power source, and power came on a steady red light. I plugged it back into the puta and it came on again. I have not turned the monitor off again for fear of the blinks, and has been working great for close to a week now. Hope it helps someone else out there. Richard
