- Step 2: Disconnect Battery and Screen Cables
Once the back cover is removed, locate the battery connector and the display flex cable connector on the motherboard. Use a plastic spudger or tweezers to gently disconnect these cables. This is a critical step to prevent short circuits during the repair. (Refer to video: 0:55 - 1:29)
- Step 3: Remove the Old Screen

Once the adhesive is warm, use the prying tools to slowly and carefully separate the old screen from the tablet frame. Be gentle to avoid damaging the frame or any internal components.

- Step 5: Connect the New Screen and Battery
Carefully align the new LCD display screen with the tablet frame. Before pressing it into place, reconnect the display flex cable and the battery connector to the motherboard. Ensure all connections are secure and properly seated. (Refer to video: 2:30 - 2:45)
