A broken laptop screen could make the laptop unusable however the good news is its totally fixable.  You can follow these step-by-step instructions for replacing a broken laptop LCD.

Whether the screen is broken or has too many dead pixels with the right tools, a little technical know-how, and a bit of patience you can replace a broken laptop LCD.

 Depending on the make and model of your laptop, the internal hardware and specific steps may vary. The general process however, should be the same.

Should you try this fix?

If accidental damage is covered under your laptop’s warranty, don’t do this fix yourself. Get the laptop repaired under the warranty.

These steps need technical information and we strongly recommend letting a professional do the repair job if you are not a technical person. You may be able to save some money on replacement by following steps but you can also damage other parts like screen cable, hinges, brackets, inverter boards, webcam, Wi-Fi cables or motherboard in worst case.

Finally even if you follow the instructions you do it at your own risk. Neither Royal Computer nor any of its representatives can be held responsible for injury, damage, or loss of data.

Getting a replacement screen and tools

To begin your fix, you’ll need a few tools and a replacement LCD screen. For tools, I recommend a screwdriver with a variety of small bits, such as a Phillips #00 and/or Torx T5. The screwdriver you use may vary based on type of screws on the screen panel.  It’s also a good idea to have a few thin metal blades. These are really handy for removing the trim that surrounds the screen.

As for the replacement LCD, you should be able to buy one either from the laptop manufacturer’s authorized parts dealer or a third-party supplier. Based on the screen, they usually cost between £60 and £300 or even more if it’s a high-end display like retina display or you buy an OEM replacement. The only way you make sure you got the right screen is to remove the broken one and check the part number with supplier.

Step 1: Disconnect the power source and Remove Battery

Make sure the power supply is disconnected and the battery is removed; wait for a minute or 2 for safety.

Step 2:  Remove the screen bezel

Carefully examine the bezel around the screen. You’ll need to remove this bezel to access the screws that hold the LCD panel in place.

Usually On laptops, several rubber cushions hide screws, which hold the bezel in place. you’ll need to remove these cushions and the screws that are underneath.

With the hidden screws removed, use a thin metal blade to pop loose one of the bottom corners and work around the bezel with a plastic card or similar tool.

Note: Your laptop may not have cushions or hidden screws. The bezel may simply snap onto the lid or be held in place with double-side tape. Just, adapt the instructions to fit your specific laptop. You can get more information from the service manual of the laptops.

No matter how, you’ll need to completely remove the bezel before next step.

Step 3:  Remove the broken LCD panel

With the LCD’s mounting brackets uncovered, you can remove the screws that secure the panel to the lid. Then rest the display front-side-down on the case and disconnect its cable.

If your laptop was made before 2010 and has a fluorescent LCD backlights, it will likely have two or three cables. You need to disconnect all these cables.

Next, locate the label on back of the LCD panel and note the model number. With this model number you should be able to get an exact match for your damaged screen.

Step 4: Install the new LCD panel

Once your new screen arrives, unpack it and make sure it matches the broken one. If the dimensions, mounting brackets, resolution, model number and connector all match, you ready to install the screen. Connect the new panel to the cable, position the panel in the lid, and secure it using the appropriate screws.

Step 5:  Test the new LCD panel and reinstall the bezel

Before reattaching the bezel and putting everything back together it’s better to test the new panel. Make sure all the connections connected safely then reconnect the battery and/or power cable and turn the machine on. If the display works, you just need to put back the bezel and any external screws and rubber cushions. The repair is now complete.
