After Microsoft splash screen the monitor goes blank except for "no signal" messages if I turn off/on the monitor. I checked the monitor menu. Under Misc dropdown the Input is empty. Clicking input bring s a list of VGA,DVI, and EXIT. I try to use the VGA option, but it keeps switching back to DVI.I have tried this on two different computer with the same result.Please help.

power on and power on led glows normal , not yellow or flash.
then this happens splash. attached, 2014 made.
then that tells you screen is NOT DEAD is it? now? here?
(PC is dead or missing)

• NO connections on 1 or more inputs.
• NO sync
• no signal
• OUT OF RANGE

and goes black screen NEXT,. if all that fails power supply is bad.
if all that works the menu button works for 15 seconds turned on with no PC, and also works on all PCs if connected to one that are all good and not sleeping. test the monitor on 2 PCs if confused.

Well, at least you got it sorted out and everything is working fine now.

check to see if the monitor plug is loose, it's a possibility.

Use the self test feature.. follow the steps..

1. Turn off both your computer and the monitor.
2. Unplug the video cable from the back of the computer.
3. Turn on the monitor.
If the monitor is functioning properly, you will see a box in the illustration below.
This box appears during normal operation if the video cable becomes disconnected or
damaged.
4. Turn off your monitor and reconnect the video cable; then turn on both your computer and the
monitor.
If your monitor screen remains blank after using the previous procedure, check your video
controller and computer system; your monitor is functioning properly.

Warning

The Power supply inside the monitor can be hazardous and donot open the monitor while power on.

Donot work with the monitor when it is open and the power supply is on.

If there is something wrong with the input signal, a message appears on the screen or the
screen goes blank although the power indicator LED is still on. The message may indicate
that the monitor is out of scan range or that you need to check the signal cable.

Ive seen this on other monitors. Look for a 1 and 2. Some monitors do NOT auto detect a signal, and this one might not. Look for a way to set the monitor from Digital input to VGA input. Try that and see.

You most definately have bad capacitors in the power supply. try and get it repaired as soon as possible, not an expensive repair that iv'e seen.

Problem with the monitor, monitor cable, or video output. For monitor, if you have more than one input, make sure it's set to the correct one. Try a different cable. Try a different monitor. Check your video card settings--if you see the BIOS bootup screen while it's coming up then the Windows splash screen, then monitor blanks out, it's a Windows display setting. Boot into safe mode, then change settings--

• Turn the computer on or Restart the computer
• Start tapping the F8 key. The Windows Advanced Boot Options Menu appears. If you begin tapping the F8 key too soon, some computers display a "keyboard error" message. To resolve this, restart the computer and try again.
• Ensure that the Safe mode option is selected (the top option)
• Press Enter. The computer then begins to start in Safe mode.
• When you are finished with troubleshooting, close all programs and restart the computer as you normally would.

Check connections, Hertz rate, and settings (if you can read them). Otherwise, it may be time to whip out the cash and get a new monitor and/or computer.

If screen says "Signal cable not connected " all the time till power led switches to Amber chances are monitor is ok and problem is with graphic card or cpu.Connect to Known working CPU and confirm that monitor is the problem.
If same problem persists on another working cpu after changing signal cable,the interface board in the monitor could be defective.

PLease rate solution and provide feedback.

This problem is most likely to be caused by a bent or broken pin on the CRT video cable at the VGA connector, OR, this could also be caused by a damaged VGA connector on the back of the laptop. If neither VGA connector is at fault, the problem could be caused a damaged (kinked) CRT data cable, or internal damage to the VGA connector on the back of the laptop, though I suspect the problem is more likely to be external, and you probably won't have to disassemble the laptop to locate the culprit...
