3. Setup and Installation

This section outlines the general steps for replacing the LCD screen and touch panel. Specific tools (e.g., heat gun, prying tools, small screwdrivers) are required and not included.

1. Power Off Device: Ensure your CHUWI Hi10 Air tablet is completely powered off before beginning any disassembly.
2. Remove Back Cover: Carefully use a prying tool to open the tablet's back cover. Be gentle to avoid damaging internal clips or components.
3. Disconnect Battery: Locate and disconnect the battery connector from the mainboard to prevent accidental short circuits during the repair.
4. Disconnect Old Display/Touch Cables: Carefully detach the flex cables connecting the old LCD and touch panel to the mainboard. These are typically secured with small latches.
5. Remove Old Display Assembly: If the old display is glued, use a heat gun on a low setting to soften the adhesive around the edges of the screen. Once softened, carefully pry the old display assembly off the tablet frame.
6. Clean Frame: Thoroughly clean any remaining adhesive or glass fragments from the tablet frame.
7. Test New Display (Pre-installation): Before fully installing, connect the new LCD and touch panel flex cables to the mainboard. Reconnect the battery and briefly power on the tablet to test the display and touch functionality. Do not apply adhesive yet.
8. Install New Display: If the test is successful, disconnect the battery again. Apply new adhesive (not included) around the tablet frame. Carefully position the new LCD screen and touch panel assembly onto the frame, ensuring proper alignment.
9. Secure Flex Cables: Reconnect all flex cables securely to the mainboard.
10. Reconnect Battery: Reconnect the battery connector.
11. Reassemble Back Cover: Carefully reattach the tablet's back cover, ensuring all clips engage properly.
12. Final Test: Power on the tablet and perform a comprehensive test of all display and touch functions.

4. Operating

Once the new LCD screen and touch panel are successfully installed, the tablet should function as normal. Power on the device and verify the following:

• Display Functionality: Ensure the screen powers on, displays images clearly, and has no dead pixels, lines, or discoloration.
• Touch Functionality: Test the touch response across the entire screen. Drag an icon around, open apps, and use multi-touch gestures to confirm full functionality.
• Brightness Adjustment: Verify that screen brightness can be adjusted through the tablet's settings.

5. Maintenance

To ensure the longevity and optimal performance of your new screen:

• Cleaning: Use a soft, lint-free cloth (preferably microfiber) to gently wipe the screen. For stubborn smudges, slightly dampen the cloth with water or a screen-specific cleaning solution. Avoid harsh chemicals or abrasive materials.
• Protection: Consider using a screen protector to guard against scratches and minor impacts.
• Avoid Pressure: Do not apply excessive pressure to the screen, as this can damage the LCD or touch digitizer.
• Temperature: Avoid exposing the tablet to extreme temperatures, which can affect screen performance and lifespan.

6. Troubleshooting

If you encounter issues after installation, consider the following:

• Screen Not Turning On / Black Screen:
  • Ensure all flex cables (LCD and touch) are securely connected to the mainboard.
  • Verify the battery is properly connected and charged.
  • Perform a hard reset of the tablet (refer to your tablet's original manual for instructions).
• Touch Not Responding / Partial Touch:
  • Check the touch panel flex cable connection to the mainboard.
  • Ensure there are no foreign objects or debris between the screen and the frame.
  • If only parts of the screen are unresponsive, it might indicate a faulty touch digitizer or an issue with its connection.
• Display Issues (Lines, Discoloration, Flickering):
  • Re-seat the LCD flex cable connection.
  • Ensure the flex cable is not bent, creased, or damaged.
  • If the issue persists, the LCD panel itself might be faulty.
• Tablet Not Powering On After Installation:
  • Double-check all internal connections, especially the battery.
  • Ensure no components were accidentally damaged or short-circuited during installation.

If troubleshooting steps do not resolve the issue, contact the seller for further assistance.

7. User Tips

• Handle with Care: LCD screens and touch panels are fragile. Always handle them by the edges and avoid touching the display surface directly.
• Static Electricity: Wear an anti-static wrist strap during installation to prevent damage to sensitive electronic components.
• Organize Screws: Keep track of all screws and small parts during disassembly. Using a magnetic mat or labeled containers can be very helpful.
• Test Before Final Assembly: Always perform a full test of the new screen's functionality before applying any adhesive or fully reassembling the tablet. This saves time and effort if a component is faulty or incorrectly installed.
