How to Replace a MacBook Pro 2019 Screen (Step-by-Step Guide)
Is your MacBook Pro 2019 showing a cracked display, flickering lines, or no image at all? Don’t worry — with the right tools and some patience, you can replace the screen yourself. Here’s a simple step-by-step guide to walk you through the process.
🔧 Tools You’ll Need
- Polar Tech Phone Repair Toolkit (Suction cup, Tweezers, Spudger, Precision screwdriver set)
🛠️Step 1: Remove the Bottom Cover
This step can be a bit tricky and requires some skill and patience.
-
Use a P2（1.2mm） screwdriver to remove the screws on the bottom case.
-
Place a suction cup on the bottom cover to lift it gently, then run a plastic pry tool along the edges to pop it open and remove the cover safely.
🔌 Step 2: Disconnect the Battery & Cables
To avoid any short circuits, carefully disconnect the battery connector first.
-
Detach the power detection cable connectors.
-
Be careful — There are many different types of screws in this section, so make sure not to mix them up.
🖥️ Step 3: Remove the Damaged Screen
Now it’s time to work on the display assembly.
-
Open the MacBook slightly and position the screen like a book stand.
-
Unscrew the hinges and disconnect the display flex cables.
-
Carefully lift away the damaged screen.
💻Step 4: Install the New Screen
- Gently adjust the hinge to about 90° angle.
-
Align the replacement screen with the hinges.
-
Reconnect all flex cables securely (Wi-Fi, display, and camera cables).
-
Screw the hinges back into place and check the alignment.
⚠️ If the Wi-Fi doesn’t show up after installation, double-check the antenna cable connections.
✅ Step 5: Reassemble & Test
-
Reconnect the battery cable.
-
Place the bottom cover back and secure it with the screws.
-
Power on your MacBook to test the new screen.
💡 Final Tips
-
Work slowly and carefully — rushing can damage delicate cables.
-
Keep screws organised, as different lengths fit in different spots.
-
If you’re unsure, seek professional repair help.
Replacing your MacBook Pro screen can save you much money compared to a repair shop, and it’s a satisfying DIY project if you love fixing your own tech.
