It may be that your backlight has burnt out, or your LCD inverter has gone bad, if you can hear a high pitched sound coming from the screen it is more than likely the converter, you can order replacements online...

Monitor is dark. how to fix?


Walt, hold the Fn key down again, and tap once more on the Acer, F5, Display Toggle-Over key.

There are at least 3 display options available;

1) Internal display of laptop ONLY

2) Internal display of laptop AND external display

3) External display ONLY.

Were you just using the external display for more 'display real estate room', or was/is there a problem with the internal display of the laptop?

Was no problem? Is now? Even when using the guidance stated above for the Fn and F5 key?

Then if your laptop uses a CCFL for a Backlight, it also uses a screen Inverter. Screen Inverter is bad.

If it doesn't use CCFL/s for a backlight, and uses LED backlighting, replace the LCD screen.
The LED backlighting is incorporated in the LCD screen assembly, and you ain't replacing it.
Replace the entire LCD screen.

Post the laptop manufacturer name, and model number in a Comment. Model number is on Bottom of laptop.

Have a Gateway Notebook KAV-60 with a broken screen. Trying to connect to an external monitor without any prompts or commands, as I can't see the screen. With an Acer Netbook I just plugged in the


Make sure the vga cable is in tight on the kav-60 and the external monitor.

Try the keystrokes to toggle the display. Normally you would Press and Hold the FN function key located at the lower left on the keyboard then hit the key F1 thru F12 that toggles the display. The correct F1 thru F12 key to hit will have LCD/CRT on it or it will have the icon of a display. The display toggles in three stages ( laptop only, external only or both laptop and external).

As soon as it come on it shutdown and lcd is dark but you still can see in dark lcd


It doesn't sound like the system is shutting down. It sounds more like the LCD display back-light isn't working. Try connecting an external monitor to you system and booting it up. You may find that the external monitor has video. You may also toggle through the three state video selections. Hold down Fn and tap F7. this should take you through all three steps. Good luck.

If this was helpful Please rate the solution high. thanks.

LCD is on...seems like backlight is not functional; when external monitor connected, boot-up and bios screen visible. After boot-up, screen goes to "power save" mode and will not return


Use the 'FN' key (blue coloured?) and one of the other blue-coloured keys to "toggle" the video:

1. LCD only
2. external monitor only
3. both LCD & external

After boot-up, Windows defaults to "LCD only", and so the external monitor goes to "sleep".
