Guide to replacing the screen of your laptop

How to replace the screen of your Asus laptop

Without a screen, it is safe to assume a computer, desktop and laptop alike, is useless. You cannot access content online or even work without being able to see what you do. Because an unfortunate event can always happen and in that case, you want it to be repaired quickly, here is a guide to replacing the screen of your Asus laptop, explained step by step.

The difference between the touchscreen and an LCD screen

Today touchscreens are ubiquitous. They are present in your phone, tablets, laptops, and appliances (ex. Refrigerators). Basically, a touchscreen allows you to interact directly with the display using your finger or a stylus instead of a mouse, keyboard or touchpad.

When touchscreen breaks the device may still function. Touchscreen (aka digitizer) is the thin transparent layer that reads (“digitizes”) the signal (your touch) and provides the information necessary for the processor to carry out your command.

The Touchscreen and the LCD screen are two separate parts. It is possible for the touchscreen to be broken and for the LCD screen behind it to still function. The LCD screen displays the image and when it is broken, you can still use the touchscreen, but the panel will have dark spots or crack (or both). If both are damaged, you may still see parts of the image and the touchscreen may partially function, but your device is no longer functional. Although you can use your laptop with an external monitor, it has lost one of its most attractive features – portability. We will see how to replace the screen of your Asus laptop further in this guide, but for now let's see the potential issues you may encounter:

LCD screens – some of the most common issues

• No picture
• Screen turns off after a short time
• The screen is very dark and hard to see.
• The screen is white with no picture
• The screen shows a single line or a few colored vertical lines that shouldn’t be there
• Takes long time for the screen to turn on
• The screen displays “No signal”

What causes LCD screen problems?

1. Power supply

The power supply is responsible for supplying electric current to every component of an LCD laptop screen. Any issue with the power supply can damage your device as well as the screen.

2. Backlight

The backlight provides the light that passes through the LCD crystals. When the backlight is damaged, your Asus screen will appear dark or faded. You may be able to improve the image by maximizing the brightness, but a repair will be necessary.

3. Inverter

The inverter board is usually located on the bottom side of the Asus LCD screen. The inverter provides power to the screen's backlight module. It, also, monitors that the LEDs are stable and working. If the inverter is faulty and cannot supply the required current and voltage to the backlight the screen brightness will be affected.

4. The controller card

The controller board/card not only decodes the signal from the graphics card but controls the inverter, power supply and the LCD screen.

5. LCD screen

From physical damage to faulty pixels, the LCD screen is subject to many different issues. Although, we have made huge progress in the durability of these screens they still remain fragile.

Do not worry, these parts can be replaced or repaired. We can help you locate the correct parts for your ASUS device.

Screen Repair – doing it yourself

The first bit of advice we give to anyone wanting to replace or repair the screen of their laptop is to work methodically and with patience. For those that do this on a regular basis, it is a fairly easy and quick process. You first need to have a clean and well-lit work space.

If you are not comfortable taking your device apart or replacing the screen, you should find an ASUS certified professional repair service.

Most repair shops will ask you to purchase the parts of the screen, Asus-accessories is here to help you locate the exact parts you will need for your repair and to provide them at the best price.

Follow the 5 steps below to successfully repair and replace the screen on your Asus laptop. The instructions below are meant as a generic guide. For example, the screws we mention may be located in a different place on your specific laptop.

1. Assess the problem or damage

Does your PC work properly

Does your laptop power up successfully? We recommend that you hook your laptop up to an external monitor. You may need to go to "Settings" or use some function keys for the external display to be recognized. If the external monitor works properly then you can infer that the issue is with your laptop screen assembly or the EDP/LVDS cable.

Inspect the laptop

Once you have determined that it is not another component such as the graphic card or a software issue, you should inspect the physical damage (if any). Is the frame around the screen (bezel) damaged, is the screen itself damaged, is there an impact point. If the Bezel was damaged you will have to purchase a new Bezel. Please note that sometimes these are only sold as part of the complete screen module. You should verify that the hinges are intact and well secured as well. The cables connecting the LCD to the motherboard run through the hinges.

2. Find the correct screen

Steps to replace an Asus laptop screen

Remove the power sources

To replace your screen, first turn off your Asus laptop and make sure that it is unplugged from a power source. You should, also, remove the battery to avoid causing any other issues. Remember, avoid touching any components without being grounded…static electricity can damage your components!

The screen bezel may have some screw covers usually near the bottom of your laptop screen near the hinges.

Carefully remove stickers and screws

Carefully remove the screw covers using a pin or the wedge in the kit shown in the link above. Store these to use when installing your new screen.

You’ll then want to use the proper screwdriver to remove the screws. Do not apply excessive pressure when removing the screws. Store the screws in a dish.

Remove bezel

Remove the Bezel using the wedge or a putty knife. Take your time. You do not want to damage the Bezel or have to purchase a new one. The wedge is used to pry the bezel from the LCD cover. There are plastic tabs at regular intervals that hold the screen and bezel in place. You will need to apply enough pressure to pull them apart.

If you damage the bezel, we help you find the model for your computer.

Remove the LCD screen

Now you should have unfettered access to the LCD screen. It will be secured onto the laptop’s metal frame. There will be two screws at the top corners. You may find a few more screws securing the LCD on the sides and in some cases a heavy-duty tape holding the LCD in place. You will have to remove these. Place the screws in a different dish (label the dish). If you had to remove any adhesive, you will need to replace with new adhesive to install the new screen properly.

Disconnect cable connectors

Be careful, your screen is still connected to the bottom case by the EDP/LVDS cable. You will need to disconnect the cable. If there is any adhesive tape, remove it before pulling the connectors apart.

Apply straight even pressure when pulling. Do not twist.

Insert the new screen

Now you will be re-assembling. Simply follow the steps above in reverse order. Place the new screen flat and connect the EDP/LVDS cable. Please ensure that the connectors are properly aligned. Attach the new screen with the proper screws and adhesive to hold the LCD in place.

Reattach the bezel

Put the bezel back on. Line it up so that it snaps properly into the screen case. Make sure the Bezel is nice and snug. Replace the two screws and screw covers.

Power up

Put the battery in, connect your Laptop, and start it up.

Update your BIOS and drivers

It is always recommended that you update the BIOS and drivers after installing new equipment to make it run properly. Congratulations you have replaced your Asus laptop screen by yourself.
