5. Installation Guide

Disclaimer: This guide provides general steps. Due to the intricate nature of tablet disassembly and reassembly, professional installation is strongly advised. SRJTEK is not responsible for any damage caused during self-installation.

1. Preparation: Ensure your tablet is powered off. Gather your tools and a clean, well-lit workspace.
2. Disassembly: Carefully open the tablet casing. This often involves heating the edges to soften adhesive and using prying tools. Locate the damaged digitizer.

4. Clean Surface: Thoroughly clean the frame where the new digitizer will be installed, ensuring no dust or old adhesive remains.
5. Connect New Digitizer: Carefully connect the flex cable of the new SRJTEK digitizer to the motherboard. Ensure it is seated correctly and securely.
6. Test Functionality (Before Final Adhesion): Before fully adhering the new digitizer, temporarily power on the tablet to test the touch functionality across the entire screen. If it works correctly, power off the tablet again.
7. Apply Adhesive: Apply the provided adhesive strips around the frame where the digitizer will sit.
8. Install New Digitizer: Carefully align and place the new digitizer onto the tablet frame, pressing gently to secure it with the adhesive.

7. Maintenance

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

• Cleaning: Use a soft, lint-free cloth and a screen cleaner specifically designed for electronics. Avoid harsh chemicals or abrasive materials.

8. Troubleshooting

If you encounter issues after installation, consider the following:

• No Touch Response:
  • Ensure the flex cable is securely and correctly connected to the motherboard.
  • Check for any visible damage to the flex cable or connector.
  • Restart the tablet.
• Partial Touch Response / Dead Spots:
  • This could indicate an issue with the digitizer itself or an improper connection. Re-check the flex cable connection.
  • Ensure no debris is trapped between the digitizer and the LCD.
• Screen Flickering / Display Issues:
  • Note that this product is a digitizer, not an LCD. Display issues are typically related to the LCD itself or its connection, not the digitizer.

If troubleshooting steps do not resolve the issue, it is recommended to seek assistance from a qualified repair technician or contact SRJTEK customer service.
