What You'll Need

Before we even think about touching your phone, it's super important to have all the right tools and a replacement screen ready. Trust me, you don't want to get halfway through and realize you're missing something crucial! Here's a list of what you'll need:

• A new LCD screen for Huawei Y7 2019: Make sure you buy a screen that's specifically designed for the Y7 2019 model. There are tons of options online, so do a little research and read reviews to find a reputable seller. Look for screens that come with adhesive, as this will make the reassembly process much easier.
• A Phillips head screwdriver: You'll need a small Phillips head screwdriver to remove the screws holding your phone together. Make sure it's the right size to avoid stripping the screws.
• A plastic opening tool or spudger: These tools are essential for prying open the phone without damaging the plastic housing. Never use metal tools for this, as they can scratch or break the plastic.
• A suction cup: A small suction cup can be really helpful for lifting the screen away from the phone body.
• A heat gun or hairdryer: Applying heat to the edges of the screen softens the adhesive and makes it easier to remove. Be careful not to overheat the phone, as this can damage internal components.
• Tweezers: Tweezers are useful for handling small parts and disconnecting delicate connectors.
• A SIM card removal tool or paperclip: You'll need this to remove the SIM card tray before you start disassembling the phone.
• Protective eyewear: Safety first! Wear protective eyewear to protect your eyes from any small shards of glass that might come loose during the screen removal process.
• Anti-static wrist strap (optional but recommended): This will protect your phone from electrostatic discharge, which can damage sensitive electronic components.
• A clean, well-lit workspace: Choose a clean and organized workspace where you can easily see all the parts and keep track of them.

Having all these tools ready will make the whole process smoother and less stressful. Trust me, preparation is key!

Step-by-Step Guide to Replacing the LCD

Alright, now that we have all the necessary tools and a replacement screen, let's get down to business! Remember to take your time and be patient. Rushing through the process can lead to mistakes and potentially damage your phone.

Step 1: Power Off Your Phone

This is the most important step! Before you do anything else, make sure your Huawei Y7 2019 is completely powered off. This will prevent any electrical shorts or damage to the internal components.

Step 2: Remove the SIM Card Tray

Use the SIM card removal tool or a paperclip to eject the SIM card tray. Set the tray aside in a safe place.

Step 3: Apply Heat to the Edges of the Screen

Using a heat gun or hairdryer on a low setting, gently heat the edges of the screen for a few minutes. This will soften the adhesive that holds the screen in place. Be careful not to overheat the phone, and keep the heat moving to avoid damaging the screen or internal components.

Step 4: Use the Suction Cup and Plastic Opening Tool to Separate the Screen

Attach the suction cup to the screen near the bottom edge. Gently pull up on the suction cup while inserting the plastic opening tool into the gap between the screen and the phone body. Work the plastic opening tool around the edges of the screen, carefully separating the adhesive. If you encounter resistance, apply more heat. Be extra careful around the corners, as they are more prone to cracking.

Step 5: Disconnect the Screen Cables

Once you've separated the screen from the phone body, carefully lift the screen up from the bottom edge, like opening a book. Be careful not to pull the screen up too far, as there are still cables connecting it to the motherboard. Use the plastic opening tool or a spudger to gently disconnect the screen cables from the motherboard. There are usually one or two ribbon cables that need to be disconnected. Be very careful when disconnecting these cables, as they are fragile and can be easily damaged.

Step 6: Remove the Old Screen

Now that the screen cables are disconnected, you can remove the old screen completely. Set it aside in a safe place.

Step 7: Clean the Frame

Before installing the new screen, it's important to clean the frame of the phone to remove any old adhesive or debris. Use a clean cloth and some isopropyl alcohol to clean the frame thoroughly.

Step 8: Connect the New Screen Cables

Carefully connect the new screen cables to the motherboard. Make sure the cables are properly aligned and securely connected. Gently press down on the connectors to ensure they are fully seated.

Step 9: Test the New Screen

Before you reassemble the phone, it's a good idea to test the new screen to make sure it's working properly. Temporarily reassemble the phone by aligning the screen with the phone body and pressing it into place. Power on the phone and check if the screen is displaying correctly. Test the touch functionality to make sure it's working properly. If everything is working as expected, you can proceed to the next step.

Step 10: Reassemble the Phone

Now it's time to reassemble the phone. Carefully align the screen with the phone body and press it into place. Make sure the screen is properly seated and that there are no gaps around the edges. If your new screen came with adhesive, remove the protective film and press the screen firmly into place. If not, you can use some double-sided adhesive tape to secure the screen.

Step 11: Reinstall the SIM Card Tray

Reinstall the SIM card tray.

Step 12: Power On Your Phone

Power on your phone and enjoy your new screen!
