Why Does an LCD Screen Break?
Before we dive into the steps for fixing an LCD screen, it's helpful to understand why and how the screen may break. The LCD (liquid crystal display) on most phones is a sensitive component that shows images and data. It is usually covered by a layer of protective glass, but when the phone is dropped or subjected to pressure, the glass and the LCD can be damaged.
Common signs of a broken LCD screen include:
Visible cracks in the screen
Flickering or distorted images
Black spots or dead pixels
Lack of touch responsiveness
A completely black screen even though the phone is on
If you experience any of these issues, it’s time to assess the damage and decide if a DIY repair is a good option.
Step 1: Assess the Damage
The first thing you should do is assess whether it’s just the glass that’s cracked or if the LCD itself is damaged. In some cases, the outer screen (glass) may shatter while the LCD beneath remains functional. This is important because if it’s only the glass that’s broken, your fix might be much simpler and cheaper.
Here’s how to tell if the LCD is damaged:
If the screen is completely black, even though you can still hear notifications or calls, the LCD is likely broken.
If there are visible lines, dead pixels, or flickering areas on the screen, the issue is with the LCD itself.
If the touch function is not working, it usually means the digitizer (the part responsible for touch sensitivity) has also been damaged.
Once you’ve determined that the LCD needs replacement, you can move forward with the repair process.
Step 2: Gather the Necessary Tools and Parts
DIY repairs require a specific set of tools, and it’s important to have everything ready before you begin. Here's a list of tools and parts you'll need:
Tools:
Precision screwdriver set (including a Phillips head and a Pentalobe screwdriver if you’re fixing an iPhone)
Plastic pry tool or plastic card (to separate the screen from the frame)
Suction cup (to help lift the screen)
Tweezers (for delicate parts)
Heat gun or hair dryer (to soften the adhesive)
Adhesive strips or glue (to reattach the screen)
Replacement Parts:
Replacement LCD screen specific to your phone model (iPhone, Samsung, etc.)
Screen protector (optional, but a good idea to protect the new screen)
You can find these tools and replacement parts online or at a local electronics store. Be sure to get parts that are compatible with your specific phone model.
Step 3: Power Off the Phone and Prepare Your Workspace
Before starting any repair, make sure to power off your phone completely. Removing a screen or tinkering with internal components while the phone is on can cause short circuits or even damage the motherboard.
Prepare a clean, well-lit workspace to avoid losing any small screws or components. Place all the tools within reach, and keep a small container nearby to store the tiny screws you’ll be removing.
Step 4: Removing the Broken LCD Screen
The next step is to carefully remove the broken screen. Follow these steps:
1. Remove the screws:
Use the screwdriver to remove the screws located near the charging port (on an iPhone) or the screws that hold the phone's back cover in place for other brands. Keep these screws safe, as you’ll need them later.
2. Apply heat:
Gently heat the edges of the phone using a heat gun or hair dryer. This helps soften the adhesive that holds the screen in place, making it easier to remove without causing damage to internal components.
3. Lift the screen:
Place the suction cup on the front of the phone and gently pull upwards to lift the screen from the frame. If the suction cup doesn't work well, use the plastic pry tool to carefully lift the edges of the screen. Be careful not to force anything as you risk damaging internal connections.
4. Disconnect the cables:
Once the screen is loose, carefully disconnect the ribbon cables attaching the LCD to the phone’s motherboard. Depending on your phone model, this step may vary slightly, but you should see one or more cables that need to be disconnected before removing the screen entirely.
Step 5: Installing the New LCD Screen
Now it’s time to install the new LCD screen.
1. Connect the new screen:
Take your replacement LCD screen and align it with the connectors on the phone’s motherboard. Carefully attach the cables back into their respective slots, ensuring they’re secure. Loose connections can result in display issues or a malfunctioning screen.
2. Place the new screen:
Once the screen is connected, place it back onto the frame. Make sure it sits evenly on all sides. Apply pressure gently, being careful not to damage the new LCD.
Step 6: Reassemble the Phone
With the new LCD screen in place, it’s time to reassemble your phone.
1. Reattach the screws:
Use the screwdriver to reinsert the screws you removed earlier. Be sure each screw is tightened securely, but don’t over-tighten, as it can strip the threads or damage components.
2. Test the phone:
Before you seal everything back in place, power on your phone to make sure the new screen works correctly. Check that the display is functioning and that the touch response is smooth. If something isn't working, you may need to reopen the phone and check the connections.
Step 7: Apply Adhesive and Finish
If everything works as expected, you can now secure the screen permanently by applying adhesive strips or glue around the edges. This step ensures the screen stays in place and gives your phone a factory-finished look.
Once the adhesive is applied, allow it to set for a few minutes before using the phone. For extra protection, consider applying a screen protector to avoid future damage.
Common Mistakes to Avoid
Not disconnecting the battery: Forgetting to disconnect the battery can result in electrical damage to the phone.
Forcing the screen out: Always use gentle pressure when removing the screen; forcing it can damage the internal components.
Using too much heat: Overheating the phone can warp the screen or damage sensitive parts inside.
