My acer aspire e5 517 laptop has a black screen. Power light comes on and screen flickers a little but nothing more. What can be the problem?


The backlight has failed. You cannot separate it from the screen, so you'll have to replace the screen. You can get replacement screens by googling Acer laptop screen replacements. You may find a You Tube video that shows you how to replace it, too.

How do i swap outscreens form one acer aspire to another i have a old one and want to replace the screen on my other which got stepped on


Swapping out is not that tough.

What you do need to know however, is if the LCD screen from the older Aspire One netbook, will work in the 'other' one.

A newer model of Aspire One may Not have the same specifications of it's LCD screen, as one in per se, an older Aspire One.

The screen size may be comparable, the finish also. (Glossy or Matte)
But the voltage requirements, signal requirements, and other specs may be different.
This means also that the Video Cable will be different.

What to do?
You're going to have to remove the LCD screen out of the older Aspire One, and out of the 'other' Aspire One, and look at the information on the back of the LCD screens.

Look at the manufacturer, and model number.
Also of course, it will only take a few seconds to see if the Video Cables are compatible.
If they aren't, it isn't worth going any further.

[ In looking from a brief search, it seems all Aspire One laptop/mini's use a 40-pin video cable connector,

Looks good so far ]

If the older Aspire One LCD screen video cable, will not plug into the 'other' Aspire One motherboard, you can't use it. Can't use the older Aspire One LCD screen.

IF, the video cables appear to be exactly the same, then I would recommend looking up the specs for both LCD screens, on the internet.
Or post in a Comment on here, and I'll look it up.

(Manufacturer name, and model number's on back of both LCD screens)

Also a Primer;
An LCD screen cannot produce light. It needs an additional light source.
A Backlight is the additional light source.

A Backlight is a CCFL.
Cold Cathode Fluorescent lamp.
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.

[ Note*
However your model may use LED lights for a Backlight, instead of Fluorescent lighting ]

A Inverter (screen Inverter) is used to convert the power from the laptop, for the LCD screen, and Backlight.

The LCD screen AND Inverter are a MATCHED unit.

This also needs to be looked up on the internet, to see if they are compatible, from the older Aspire One's LCD screen, to the 'other' Aspire One's screen Inverter.

There are MANY models of the Acer Aspire One.
I will post links to info I have on disassembly, to include replacing the LCD screen.

Where it states Aspire One, NAV50, click on the blue - One

This is a PDF file. The computer you are using now has Adobe Reader on it, which uses PDF files.
After you click on the file name (One) it may take up to 30 seconds before the first page comes up.

Good Morning. I wonder if anyone could help me solve my problem I have a Accer Aspire 5535 and its around 2yrs old on windows Vista. The screen stopped lighting up and then on Random days it would...


Hi,

This could be one of two things, it is either the inverter (this generates high voltage to run the back light) or it could be the back light itself.

As you have suggested, it could just be a loose wire or cable.

Replacing the inverter is relatively straightforward as it is located at the bottom edge of the LCD screen behind the plastic case. The backlight is usually part of the LCD screen and you would usually be better replacing the screen entirely.

To get at either of these components to check cables/wires etc, you will need to disassemble the screen case of the laptop, this is fairly simple if you are comfortable with disassmbling laptops.

A brief overview of the screen replacement process is below, instructions 1-4 show how to remove the case to access the inverter and cables:

1. Power off your laptop. Turn the laptop upside down so that you can see the bottom side of the laptop's case.

2. Depress the battery release latch and lift the battery and laptop ac adapter out of the laptop. Flip the computer back over and open up the LCD screen to a 90 degree angle.

3. Pull off each of the rubber buttons located along the edges of the Acer Aspire 5535 Screen. Remove each of the screws underneath the buttons with the Phillips-head screwdriver, remove keyboard.

4. Insert your fingers underneath the cover of the Acer Aspire 5535 Screen. Work your fingers around the edges of the cover to unlock it from the screen. Pull the cover off the screen and set it aside.

5. Locate the inverter board at the bottom edge of the Acer laptop screen . Disconnect the cables at the right and left end of the board that connect to the Acer Aspire 5535 Screen. Remove the screw holding the inverter board in place and then lift the board off the LCD screen.

6. Tilt the screen slightly towards you until you can see the strip of tape holding the video cable. Pull off the tape and then disconnect the video cable from the laptop case.

7. Remove the Acer Aspire 5535 LCD screen from the case. Set the new screen onto the case and reattach the video cable and tape strip. Position the replacement inverter board at the bottom of the screen and attach the screw.

8. Reconnect the inverter board's cables. Pop the plastic cover onto the Acer Aspire 5535 LCD screen and reconnect the screws. Set the rubber buttons over the screws. Reconnect the battery.

9. Turn on the laptop. Wait for the manufacturer's logo to appear on the screen to ensure the display was replaced properly.

My screen is black but when i use a second monitor, its working perfectly. How do i solve this problem? My laptop is a Acer Aspire 3935.


The problem is either a bad inverter board "more likely" or the back light behind the screen has failed. The inverter is located under the LCD screen, and the back light usually requires the whole display to be replaced because it is built right in.

start up the computer and while its running, hold a flash light to the screen. If you can see any graphics on the screen, your lcd converter burned out. If you can seen nothing, its possible that the back light lamp burned out and the best option would be to replace the screen altogether
