Good morning!
Sounds like you need a new inverter for your backlight. Or, possibly the backlight, itself.
Oh! Be sure to verify that you have not accidentally turned down the brightness on the screen. ;o)

Acer aspire one zg8 screen problem

when the inverter is the issue the screen will not light up at all ...and only shadows of the image can be visible in the light ..The fact that you do not have an image at all ...and the back-lights seam to kick in randomly ...seams more like a contact issue ..Check the plug of the screen and see if there are any problems there..or check for broken cables ..
(exclude the video card problems cause you have secondary image all is good..)
the plug is somewhere under the front the left ..

Screen Half darker

It sounds like your backlight isn't working properly. LCD screens have backlights that illuminate the colors produced upon their surfaces, so that you can easily see the screen without an external light source. In your case, it sounds like your backlights either aren't cailbrated, are damaged, or were produced unevenly.

There is most likely not a fix for this, though most all LCD screens have some form of light distortion. My own LCD screen is slightly brighter around the edges, where the backlights are located, but this is only noticeable when displaying a completely black screen.

your case is the back lights inverter or lamp damage, you have to send to repair, find a laptop hardware specialist to do that, my repair cost (lowest)

Display / LCD issue

Try adjusting the brightness setting for the LCD screen by holding down the "on" key and pressing the "+" key at the same time to make your screen darker or the "-" key at the same time to make it darker.

Monitor problem

Dear Booker3772,

From what you have written I assume you do not have a UPS system protecting the PC.

Unfortunately this mean that hardware has been damaged as electricity spikes have caused electrical stress to the components.

It would be helpfull to me if you where giving me a little bit more information but I will try to help. There are a few possibilities though that can narrow down the problem.

1. When you power up the system nothing happens - No noise no fans nothing. - Solution: The complete PSU or the fuse within is fried. (Change PSU and fire up again)

This is the most likely cause but these are also very possible.

2. When you power up the system the system fans, lights, hard disks make noise but you see nothing in the monitor except the sign. (The monitor's voltage regulation pcb is fried due to the storm) Try with a spare monitor if possible and if possible try the monitor to another PC

3. When you power up the system the system fans, lights, hard disks make noise but you see nothing in the monitor except the sign. If the monitor works fine, the PSU and the components seem to run fine most likely the components within the PC have been damaged. Not to the extend that a total failure is present but enough to create a mess. Some of the components will still probably be in good condition though. The only way to test them is by interchange one component with another.

In any case if the PC is still under warranty please go to a repair service centre and simply say that it stopped working. Do not mention storms, its your liability normally to protect the PC.
