Question about Acer Aspire 7720-6569 Notebook

Backlight on Acer Aspire 7720-6395 gone instantly

I was surfing the web and the screen went blank (mostly) you can still see the screen if you take a bright light (flashlight) to the screen and see the highlighted area. everything appears fine except the backlight is gone. I have tried using the FN+keys to adjust brightness with no change and rebooted and although it is uniform the screen is blank except where you take the flashlight; then you can see that area. I tried system restore too (fun by flashlight) I do have external CRT and I have not tried it yet-not sure exactly what I would prove except that the backlight is not on my CRT or perhaps my video card is bad or that the backlight control is on the videocard and I need a new one.

    I solved it-it was the LCD inverter; I just replaced it and the screen was fine fortunately it wasn't the screen or backlights.

    I solved it it was the LCD inverter. I replaced it and voilà it was fixed. All you have to do is make sure you get the correct inverter for your model.

The backlight is typically part of the screen assembly. You will need to order a new screen from Acer, and/or have a professional install it. Unfortunately, this is not a repairable item without proper training (component-level soldering is required, among other things); you will need to replace the entire screen.

Ny acer aspire one only shows blank screen


The backlight have went out on your screen. I had this happen on an old laptop2_bing.gif I was messing with. Check the link below for some tips.

DARK SCREEN If you shine a light on the screen, can you somewhat see the screen? Does the laptop power up properly? (can you hear it running?) Hook up an external monitor to your laptop, does the external display properly?

My acer 4520's screen is blank when i'm turning it on.


Hi,

There are approx 4 reasons why this might happen:

  1. The backlight has gone (Find a dark place and shine a torch into the screen and see if you can see an image in the background, if you see an image then the backlight has gone) - Needs a new backlight (Engineer to remove and fit) or have a new panel fitted.
  2. The panel has died - Need a new panel
  3. A cable has worked itself loose or is broken
  4. The inverter has gone - Need new inverter
  5. Long shot, the bios has got corrupted - Engineer could re-flash the bios
  6. Long shot, Mainboard onboard graphics has gone - Need new mainboard
My personal opinion is that the backlight or inverter has gone - Either way it needs to be opened up to repair it, consult a service centre and get a quote or repair it yourself if your up for it.

Thanks

Screen went from Red to Black


It Needs a new Backlight period.(Red hue is clue before complete failure). 15.4" Widescreen? Weve replaced hundreds and some can be a pain.. Run on external monitor until you can get it in for repair.

There are a ton of businesses that can replace these besides us where are you located?

Display


A really dim display like you're describing is most likely a backlight problem.  If your inverter went bad you wouldn't have any display at all.  you need to get your backlight changed.
