5. Troubleshooting

• No Display/Black Screen:
  • Ensure the 12Vdc power adapter is correctly connected and providing sufficient power (>2A).
  • Verify that the LVDS cable is securely connected to both the controller board and the LCD screen, with the dots aligned.
  • Check the video input source (e.g., HDMI cable) for proper connection and functionality.
  • Confirm the inverter board is correctly connected to both the LCD and the controller board.
• Incorrect Colors or Lines on Display:
  • This display supports 8-bit color. If using a Linux system (e.g., Ubuntu 24.04), you may need to set the color depth using a command like: xrandr --output DP1 --set "max bpc" 8. Adjust 'DP1' to your specific output.
  • Check LVDS cable for damage or improper connection.
• No Audio:
  • Ensure speakers or earphones are correctly connected to the audio output ports.
  • Check OSD settings for audio volume and mute status.
  • Verify the video source is sending an audio signal.
• Controller Board Not Responding:
  • Ensure the keyboard cable is securely connected.
  • Disconnect and reconnect the power to reset the board.

6. Maintenance

To ensure the longevity and optimal performance of your VSDISPLAY LCD screen and controller board, follow these maintenance guidelines:

• Cleaning: Use a soft, lint-free cloth to gently wipe the screen surface. For stubborn marks, slightly dampen the cloth with water or a non-abrasive screen cleaner. Avoid harsh chemicals.
• Dust Control: Keep the controller board and screen free from dust accumulation, which can affect performance and lead to overheating. Use compressed air to clean hard-to-reach areas.
• Environmental Conditions: Operate the device within recommended temperature and humidity ranges. Avoid exposure to direct sunlight, extreme temperatures, and high moisture.
