1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your display on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.

HI,
Do a power drain, this may cause by an electrical charge in the motherboard itself,Im Not really sure how it affects the display of the computer but this method usually fix such problem like that, First, removed the battery then unplugged the AC adapter the press and hold the power button or the ON/OFF button for at least 30 seconds then connect the power supply back to your computer then turn it back on, if nothing happens, there is a possibility that the problem is with the LCD or monitor itself, maybe it will need a replacement...

Open the monitor, look for blown capacitors and replace them. If problem persist, test the light bulbs and the inverter. If the inverter includes ceramic capacitor, replace it. If some of the bulbs does not do the flash - replace it. Check the transistors of the inverter. Replace if faulty.

Black screen, power button flicks


The monitor should come when the power button is pressed once - period. If not, and it continues to happen when connected to another PC, then the hardware is having trouble powering up the panel / ccds and it should be replaced/serviced according to the terms of the warranty. I suggest to bring it to an authorized service center for proper diagnosis & fix the problem. regards

Acer LCD Monitor only displays "acer" logo


You are correct, it could be a power surge that has caused it.

Try this..
Unplug the monitor from the wall.
Remove all the video connections at the monitor end.
Wait 10 minutes then plug the monitor back into the wall (do not connect the video leads)

Turn it on and see if it goes past the ACER logo now. If so, replace the video cables and try the computer.
If not, then one of these will apply and a tech will be required..
  1. The internal bios has been corrupted.
  2. The power supply inside the monitor may have issues preventing the video board from starting correctly. This could be as simple as a few failing capacitors.
Number 2 is the most likely cause with an Acer monitor though. Any local tech will be able to correct it fairly cheaply, but phone around for quotes..they can vary a lot.

HP desktop monitor problem


hi try this ,,,
  1. Ensure the video cable is connected (and connected to the correct video port).
  2. Turn off the monitor using the monitor's power button and then restart the monitor.
  3. Cycle the power on the monitor as follows:
  4. Turn off the monitor. The power light on the monitor should be off. Leave the computer turned on.
  5. Unplug the power cord.
  6. Wait 5 seconds.
  7. Plug in the power cord.
  8. Press the power button on the monitor to turn on the monitor. One of two things happens:
    1. The image from the computer displays on the monitor and you can use the computer again. This indicates that the monitor was unable to detect that the computer had awakened from suspend mode. Turn the monitor off when it is not being used or disable suspend mode. For some computers, updating the BIOS corrects these types of suspend problems.
    2. The power light on the monitor comes on but the screen displays one of the messages again. The monitor is not receiving a video signal from the computer that it can detect and use. Continue using these steps to adjust the Windows display resolution to the Monitor's native (default) resolution
    3. Connect the monitor to another computer that you know is working to determine if the monitor should be serviced or replaced:
      • If the monitor displays an image from another computer, you know that the monitor works. Troubleshoot the video connection and graphics adapter on the computer.
      • If the monitor remain blank when connected to another computer, the monitor signal processing hardware may be bad. The monitor should be repaired or replaced.
      hope it will work for u .. little_angel
