Try Unplugging the monitor and plugging back in again,,,you dont have to shut the PC down to do this,,,if it starts backup,,,then good... if it doesnt,,then you need another Monitor.
An LCD monitor is better for your eyes anyway.

To get monitor work for you, you should connect the VGA cable to CPU. When you remove the VGA cable, monitor has got nothing to display so it goes in stand by mode with orange LED on.

When i turn it on it only appears only a second , my monitor turn black


Hello Chelleydiao, hi, its either you have a CPU problem or the monitor itself. Check or use another monitor to see if the problem is fix. you see an blank monitor can also be caused by the CPU if it fails to boot. the aid the checking, do you see any orange light on the monitor? or any indication.... the led light on the screen in summary: green or blue means there is power and the CPU boots up. if orange the CPU fails to boot, if there are no lights on the Monitor panels, there are problems on the monitor. check these first....I need a much detail description.

AOC color monitor model 5En...during power on all led lights blinks then stops blinking without display action. all led lights on no more action observed.


actually if u repair an aoc monitor alone without getting connected to cpu once u switch on the monitor all led's will lit on ( green light ) it will remain on situation until u connect the vga connector to cpu that's the time led's will lit off and only the power led will remain in green condition.some aoc 5en once u power on power led is in green condition and if not connected to cpu it will be in orange condition.hope u get some idea but i am not sure if it will work with ur monitor. but as long as LEDs lit on i think no problem with ur monitor.

Can't find video signal


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.

Monitor screen blank and LED orange light flashing


For some reason, it seems as if your monitor has either lost the video signal or the capability to interpret the siganl. If you have the ability, put a second monitor (or tv) to your computer. See if you get a video siganl. If you do, then your monitor has an internal issue with the signal and needs to be addressed "hands on" by a technician. If you do not see a video, then your problem lies within your video card. Good luck.
