6. Maintenance

Proper maintenance helps prolong the life and maintain the clarity of your LCD screen.

• Cleaning: Use a soft, lint-free microfiber cloth to gently wipe the screen surface. For stubborn smudges, lightly dampen the cloth with water or a screen-specific cleaning solution. Never spray liquid directly onto the screen.
• Avoid Harsh Chemicals: Do not use alcohol, ammonia-based cleaners, or abrasive materials, as these can damage the screen coating.

  • Verify the laptop is powered on and not in sleep mode.
  • Check if the backlight cable is properly connected (if separate).
• Flickering Screen:
  • Check video cable connections for looseness or damage.
  • Update or reinstall graphics drivers.
• Horizontal or Vertical Lines:
  • Often indicates a faulty screen or a damaged video cable/connector. Recheck connections.
• Dim Display / Low Contrast:
  • Adjust brightness settings in the operating system or using keyboard function keys.
  • Ensure the backlight is functioning correctly.
• Fuzziness of Picture:
  • Verify the display resolution is set to the native WXGA (1366x768) in your operating system.
