Monitor not Running(shows only orange light)

Here's some tricks I would try. Something here, might help...
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 orange 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 monitor 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.
Good luck.

If you mean the light on your monitor is orange instead of green, it means the monitor is not receiving data from the computer.

Try another monitor.

If your monitor goes off and your PC is running and monitor display has appeared. The sign of orange light shows that there is a fault in monitor. The solution is that provide the heat or sunshine to monitor for 2 hours and then your monitor work well guaranteed.

Good Luck

Step1: The light on the monitor is blue when it is on? And orange when in sleep mode? Check to make sure all the cables are plugged in completely. Perhaps the video cable attached to the CPU is loose. Step2: First of all, check all the cables and make sure they're all securely connected. if you can, hook up your computer to a different monitor and see if it was the monitor. If that didnt work, you may wanna open up your computer and check to see if the video card is in place and fully in. And if that doesnt work, if you really wanna go the extra mile, borrow a friends video card, install it, and try to boot up your computer. Best Of Luck

The power light turning orange means the monitor isn't getting a signal from the computer. Or the monitor has a problem. If the screen shows light in the corners, the inverter is working. (If the inverter stops there is no light at all.)

The first thing to try is connecting another monitor to make sure your computer is actually starting up. If that monitor also shows nothing, you have a computer issue to take care of. Otherwise the monitor needs service.

Hi...there,
It's turns blue to power safe mode (yellow) it's prevent futher damaged to your monitor. It's seems you got a busted backlight inverter. Need to replaced a new one...Since you only got it for a few months, send it back to Acer for a replacement of a new backlight inverter... Have a nice day!

double check that all yor connections are tight. Open your PC case (unplug it) and ensure that all your fans are clean. It appears that your problem is due to loose cable connections, but this may be a good time to do some computer spring cleaning.
