8. Troubleshooting

8.1 No Display Output

• Check Power: Ensure the power adapter is securely connected to the display kit and plugged into a working power outlet.
• HDMI Connection: Verify that the HDMI cable is firmly connected between the display and the Raspberry Pi's micro-HDMI port. Try a different micro-HDMI port if available.
• SD Card: Confirm that the Micro SD card with a properly installed operating system is inserted correctly into the Raspberry Pi.
• Power Supply: Ensure your Raspberry Pi is receiving adequate power (a 5V/3A USB-C power supply is recommended for Raspberry Pi 4).

8.2 Touch Functionality Not Working

• USB Connection: Check that the USB-A to Micro-USB cable is securely connected from the display to a USB port on the Raspberry Pi.
• Operating System Support: Confirm that your operating system supports the touch functionality of this display. While most are driver-free, some configurations might require specific settings.
• Reboot: Try rebooting the Raspberry Pi.

8.3 Screen Flickering or Instability

• Power Supply: Ensure a stable and sufficient power supply is used for both the display and the Raspberry Pi.
• Cable Integrity: Check the HDMI and USB cables for any damage or loose connections.
