Your power supply is likely kaput. If it is internal to the monitor- replacing the electrolytic caps on the power supply section may remedy it. If it is external- swap with another supply of similar or greater ratings and make sure the coaxial connector is both right size and polarity.

Screen trys to show desktop, but quickly fades to


Hello,

Since the power led button is on, the problem with your monitor is the that the picture board of your monitor has develop fault, that is why it tries to show your desktop and quickly fades away.

The picture board of your monitor is bad and will need to be replaced in other for it to display.

The best thing for you to do is to take your monitor to a local repairer or any service center within your vicinity to help with the replacement of your picture board because the fault is not something you can fix on your own in other not to complicate issues.

Take care.

My Acer Al1715 monitor does not display a picture the power is fine as the green light flashes but no picture at all


The light should come on steady. Your monitor most likely has the typical failed capacitor problem. The Power Supply board in the monitor most likely has some capacitors that have failed, visible signs include swelling of the ends of the parts, but they can fail without showing any visible sgns. Replacement of the capacitors often restores operation.

No picture on monitor - green power light blinking


There's an internal electronic part/s of your monitor that is cold soldered / defective. I suggest to bring the unit to an authorized service center to properly diagnose & fix the problem. regards

Power of the Monitor keeps going out.


You need to look inside your pc and check and see if the video card is plugged in tight. Sometimes if it is loose, and it isnt connected, and causes the monitor to not show any picture, but still has power.

Base on the information given to me.

I think your computer is on sleeping mode.

first thing check if the video cable is not loose connecting the pc.

because what would happend, if it is loos it would turn on and off at times.

The other thing you can do.

right click on the desktop.
go to properties
go to screen saver
click on power

adjust the time you want your monitor to shut off.

Blank Screen..Will not power off


The flash light test only works with lcd monitor as they have back lights. Double check the connections again, also, if you can borrow a monitor try it on your pc, it may be your graphics driver needs to be uninstalled and re-installed, but you will need a monitor to see.
