Setup and Installation

This section guides you through the process of replacing the touch screen digitizer on your Zonko K105 tablet.

Tools Required (Not Included)

• Heat gun or hairdryer
• Small Phillips head screwdriver
• Plastic prying tools (spudgers)
• Suction cup
• Tweezers
• Clean, lint-free cloth
• Isopropyl alcohol (90% or higher)

Pre-Installation Check

Before fully installing the new digitizer, it is crucial to test its functionality. Connect the flex cable of the new digitizer to the tablet's motherboard connector without fully adhering it. Power on the tablet and test the touch response across the entire screen. If it functions correctly, proceed with the full installation. If not, contact support.

Installation Steps

1. Prepare the Tablet: Power off your Zonko K105 tablet completely.
2. Remove Back Cover: Carefully use a plastic prying tool to open the back cover of the tablet.
3. Disconnect Battery: Locate and disconnect the tablet's battery connector from the motherboard to prevent accidental short circuits.
4. Heat the Edges: Use a heat gun or hairdryer on a low setting to gently heat the edges of the old digitizer. This softens the adhesive holding it in place. Apply heat for 1-2 minutes around the perimeter.
5. Remove Old Digitizer:
   • Attach a suction cup to a corner of the old digitizer.
   • Gently pull up on the suction cup while inserting a plastic prying tool into the gap created.
   • Carefully work the prying tool around the edges, slowly separating the old digitizer from the frame. Be mindful of any flex cables.
   • Once loose, disconnect the old digitizer's flex cable from the motherboard.
6. Clean the Frame: Remove any remaining adhesive residue or glass fragments from the tablet frame using isopropyl alcohol and a lint-free cloth. Ensure the surface is clean and smooth for the new digitizer.
7. Apply New Adhesive: If the new digitizer does not come with pre-applied adhesive, apply a thin, even layer of B7000 or similar adhesive around the perimeter of the tablet frame where the digitizer will sit.
8. Connect New Digitizer: Carefully connect the flex cable of the new digitizer to the corresponding connector on the tablet's motherboard.
9. Position and Secure New Digitizer: Align the new digitizer precisely with the tablet frame, ensuring the camera hole and edges match. Gently press down around the edges to secure it in place.
10. Reconnect Battery: Reconnect the battery connector to the motherboard.
11. Reassemble Tablet: Carefully reattach the back cover of the tablet, ensuring all clips snap into place.
12. Final Test: Power on the tablet and perform a thorough test of the touch screen functionality.
