Same problem - unplug both computer and monitor - hold power button for monitor for 15-30 seconds...then power it back on and then power on the computer. Seems from other sites there is a power issue with the monitor - this worked for me.

Try power cycling it. Essentially, this means unplugging the cable from the back of the computer or outlet, holding the power button for 30-60 seconds and wait for any residual power to drain from the electronics inside. Afterwards, plug it back in, press the power button on your computer and see if the monitor turns on this time. This worked for me a few years ago when I had the same issue. If this doesn't work it could be caused by a faulty video card or monitor cable. You should check your VGA or other video connection and power connection to the monitor. If still nothing, try testing with another monitor or TV.
1. Turn Off Monitor by pressing power button on LCD 2. Shut down computer 3.
Unplug power cable from LCD, Once power cable is unplugged from LCD,
press and hold down the power button on LCD for 15 seconds
4. Unplug the power cable from the back of Desktop Computer and Hold down the power button on desktop computer for 15 seconds
5. Plug the power cables back into the LCD and Desktop Computer
6. Power on computer and then power on LCD, it should work
power supply issue, look at any capacitors on board for any bulged or opened capacitors. Note values and replace. Turn off, unplug and then hold power button off for 10 seconds to discharge power buss before working on it.
Press and hold the power button on the monitor until it turns off. If you press and hold the button for more then 2 minutes or so and get no response, unplug it from the power source. Then press and hold the power button down for 60 seconds while it is unplugged. then plug it back in and turn it on. that should solve your problem.
I love this one. I've actually done this many times before and have been successful.
1. Turn the computer off and unplug the power cord from the back of the tower.
2. Press and hold the power button for about 3 seconds while the computer is unplugged (this drains the remaining power from the capacitors on the motherboard).
3. Plug the computer back in and turn it on.
If that does not work, follow steps 1 and 2 again, but this time:
3. Open the computer while it is unplugged and unplug the power supply from the motherboard then hold down the power button again for 3 seconds. (You may also want to take the RAM out and put in back in)
4. Plug everything back in and turn the computer on.
Normally the OSD lock will only be displayed for 5 seconds. Regardless you should be able to get rid of it by pressing holding the up arrow key for 10 seconds. If this fails to resolve the issue try this. Disconnect power cord. Now press and hold button 1. Plug the power cord back in. You may have to press the power button while still holding button 1. The OSD lock should clear after that.
Hope this helps.
If you still get the blue power light output but it is dimmed, I've had the same problem - unplug both computer and monitor - hold power button for monitor for 15-30 seconds...then power it back on and then power on the computer. Seems from other sites there is a power issue with the monitor - this worked for me.
If you mean the on light goes dim, then I've had the same problem - unplug both computer and monitor - hold power button for monitor for 15-30 seconds...then power it back on and then power on the computer. Seems from other sites there is a power issue with the monitor - this worked for me.
i fixed this problem by unplugging the monitor, unplugging the video cables. Then hold down the power button while plugging it back in. Release power button and then press power button for on. It worked then. I got the icon for no signal, i plugged back in my monitors. Sceptre X9W
