Try shining a flashlight or a lamp on the screen and see if you can faintly see the Windows desktop in the background. If you can then the problem is the backlight. Laptop screens have a light that shines from behind the screen and lets you see the display. If this is a laptop computer it will need to go in for service. If this is a monitor for a desktop computer you can try turning it on and off a few times, or leave it unplugged for a few hours and try it again but failing that it also needs service.

Too bright


Open Power settings, dim display. I'm sure there is a brightness button on the monitor, sides or a Fn key. You can find the user manual here: http://us.acer.com/ac/en/US/content/support OR http://acer.custhelp.com/app/answers/detail/a_id/522/kw/Dim%20display/sno/1

Try and start it in safe mode. Rebbot the computer and as soon as soon as the computer starts to boot hit F8 several times this should bring it up in safe mode. If you get the compputer up in safe mode try to restore to a different date.

Let me know if this helps

Power related issue certainly, sounds as though the charger may be suspect, but I'd need to know if you were running this on battery also.

The dimming of the screen could be down to a faulty backlight, but I have a feeling thet, given the issues you also decribe, that there is a problem with some of the capacitors on the motherboard, which are causing the power fluctuation. This is not good news if it is the case, as it means the motherboard needs to come out and be checked and maybe have new capacitors.

It could also man that there is a damaged or "dry joint" on one of the circuits that provide power to the laptop

Try going to your control panel and then to display settings and adjusting your settings from there. If that doesnt work then i'd get a new graphics card. It may also be the VGA cable you are using. Try using a different one

Black Screen on Startup.


Did you try " Last known good configuration at start up. If after boot you press the F8 key where you said you went into safe mode, did you try to load the good known config. It sounds like you have a corrupted registry.

The possible reasons is that you have turned down your brightness and contrast without realizing it, to fix this simply look for a brightness key on your keyboard and turn it up. If it is missing or did not fully work, see if you can notice any image and try to get into your Display properties, click the setting tab and go into advanced and turn up your brightness and contrast from there. If this does not work, im afraid to say you have damaged your LCD screen and this would result in your dull screen appearance. Get a computer technician to take a good look at it to see what has happened if this is the case

Hope This Helps

Acer aspire 5043wlmi laptop starts but know function of lcd but works on desktop monitor


The computer's power management system automatically dims the screen when using battery power, which is one of the power-saving features.
To adjust the brightness:
  • Hold down the Fn Key located at bottom left of your keyboard next to the Ctrl key, and adjust the screen brightness using the left/right arrow keys located at the bottom right of the keyboard.
If that's not it then

A dim or dark screen does not necessarily mean a bad inverter! It could be a faulty lcd backlight bulb, inverter cable, inverter, or in some cases a motherboard failure. If your still under warranty then I would get Acer support on the phone and see what they can do.
An Inverter converts direct current (DC) to alternating current (AC).
