Monitor will not power on

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.

I think you might have the same problem I did with my E178FPb. I made a video on how I fixed it.

Thank you for using FixYa

I would try shutting down the computer in the normal way, and turning off the monitor.
Boot up and turn the monitor back on.
If it still doesn't work, then I would check the cables and power plugs and wall plugs.
Check the mouse and keyboard cable and any other cables plugged into the computer.
The next step requires a seperate monitor or laptop.
Try unplugging the monitor and pluging in another monitor. Most laptops have a common
VGA adaptor jack or even an Svideo jack.
If the other monitor does not work, Then take to a qualified technician for repair.
It could be your power supply in the computer or video controller.

I hope this was useful and please comment if this was helpful to you.

The power supply on lcd and other flat screen type monitors utilize a group of capacitors as a static pulse for the screen to energize..my bet is that one or more of those have failed...it's actually a common problem with flat screens. Most of them, those that won't power up anyways, have this exact same problem. If it's not that, then your power supply is burnt out, and if that's the case it may be cheaper to get a new monitor instead of trying to fix the old one.

If your computer is indeed running, simply unplug your monitor from the wall, and then plug it back in. This will bring your monitor out of power save mode instantly.

Try the fuse on the monitor power cord, and if this does not cure, you will have to get another monitor....pretty good prices on ebay!

The light should be lit on the power supply when its plugged into the wall. Sounds to me like the power supply might be bad. Plug it into another working outlet and if it still doesn't light up then the power supply is bad.

If it lights up then you know the outlet is bad.

I didn't have the monitor connected to the computer, and that's why the power button was unresponsive. After connecting it, the solution above worked for me.(My KVM switch was set to a computer that was turned off)

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
