If an external monitor works fine then maybe you're having issues with the LCD's backlight. It happened to my laptop and I had to replace the whole LCD itself.

Acer aspire 5310 the screen just blank and not


Possibly the monitor is defective - usually most laptops have a blue plug at the back for an external monitor, if plugging in a normal monitor brings up a screen, then likely the laptop monitor is defective. If you get a splash screen and bios info on trying to start it,it indicates your windows is defective or has lost it's start-up files - a windows reinstall will fix that.

My srceen goes Blank


Hi,

first try booting the laptop and pressing the Fn key with the numerical ( numbered key ) that has a picture of 2 screens on it. This is for booting to an external monitor. you could also try adding an external ( pc monitor ) this will eliminate any motherboard Faults.

Secondly, the graphics chip driver may be corrupt or not installed correctly. if you have a restore cd, you could try booting the laptop, with the cd in the drive.

you can then try, to see if the settings in the bios are all correct, by booting/starting the laptop and pressing esc or F2 or delete immediately as the laptop starts. ** Be-Careful** what you adjust.
My suggestion is to look for. ** default settings tab** or load setup defaults.

these are the obvious things to try, before assuming that you have a faulty graphics chip or motherboard fault.

Blank screen after boting up


There should be a display toggle key on your keyboard. This will toggle the display from the external display to the laptop lcd. Try pressing the Fn + F5 key to toggle the display.

Blank screen on start up on Acer Extensa 4620


Did you switch displays to the external video? Try hitting the Fn key and whichever function key at the top of the keyboard has a little TV screen icon over it at the same time.

My FN+F6 doesnt keep my screen on the laptop open


Change the settings from the display settings panel. (Right click on the desktop and go to display settings)
You should see 2 monitors graphically represented there. 
You can make the monitor that is greyed out active by right clicking on the monitor, and selecting active.

Have you tried to disconnect the external monitor and just booting to the laptop? If this works, then use the "e" key next to the power button to add the second monitor.

probable cause: there is an external device connected to your computer like printer, external hard drive or docking station. remove any if there is
could be a video card issue: try using an external monitor if you will get to see anything on it. if video card is integrated and you still have a warranty in your system have your motherboard replaced. when you use an external monitor be sure you know how to switch the screen from your lcd to the external monitor.

when you turn on the computer do you get to see anything come up on your screen before it goes blank?

try also removing the memory/ies of your system. see if you will get to see an error message on the screen and beeps from your computer without the memory. then try putting back 1 at a time and try using other memory slot to check if one of the slot is not working or just your memory
