    I have very similar roblem. When I wake up laptop after being in sleep mode for 2 or more hrs, the sign-in screen flashes briefly and then the screen goes black, hitting Fn + F6 then Fn again (often several time) I can get the screen back again.

    Have you try external monitor? If the external monitor is working well, the LCD back-light or inverter (which to invert low power to high power to turn the back-light on) could be faulty.

    Your one like inverter was faulty, it need replace or re-solder it by component level tech, not DIY.

Acer Aspire 9402 laptop lcd light comes on,but screen is blank. External monitor works fine. Could it be the lcd inverter?

Have you attempted to reset the monitor output?

To do so:
1. Press and hold the Fn key
2. Locate the monitor switch key (should be F6)
3. Toggle through until the LCD returns.

Good luck, I hope that is the answer for you.

No light on screen on acer aspire 5610

Hello pboppa1,

Have you tried holding the [Fn] key at lower left of the keyboard and pressing the [F6] key in the top row at the same time? The [Fn] and [F6] keys combination toggles the screen on and off.

If this solution is helpful please click a thumbs-up rating below.

Have a great day,

My laptop comes on everything lights up except the screen

it would be the blue lettered fn and f6 keys, hold fn key-then hit the f6 key to toggle display. otherwise try and reset the notebook- take out battery and unplug the unit. then push and hold the power button for 60 seconds. then put the battery and plug it back in, and try and see if that works. this has worked on my acer 5100 several times! the screen could have a problem also. this is what i worry about every time this happens 2 me. good luck! if i can help more reply.

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

Possible that the HV inverter or the CFL tubes are going bad / defective. I suggest to bring the unit to an authorized Acer service center for proper check-up / test & fix the problem. regards

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.

Got a new acer lap top and when i trn it on it turns on but the screen doesnt turn on

Laptops have the capability to use the monitor for projectors and dual monitors. In order to use those other items you have to press FN+F6 or FN+F5. This may have been pressed by accident. So press those two combinatons three or four times each. It may toggle to bring your screen on.
