Inconsistent Brightness

• Problem Description: Some areas display insufficient brightness or excessive brightness, affecting overall visual quality.
• Analysis Causes: Possible reasons include inadequate power supply in the driver circuit, aging chip components, or faulty connection lines.
• Solution:
  • Ensure that the power supply module provides appropriate voltage and current to meet each pixel’s energy requirements.
  • Use precise measuring instruments to check for any resistance anomalies in all connection lines. Replace faulty sections or adjust brightness settings as needed.

Color Mismatch

• Problem Description: The displayed colors differ from expectations, impacting product appearance and user experience.
• Analysis Causes: Potential issues include inconsistent color temperature settings, malfunctioning color adjustment modules, or variations in LED chip characteristics.
• Solution:
  • Verify that all LED chips have identical color temperature settings and ensure the color adjustment module is functioning properly.
  • Clean any dirt or grime on connection lines to prevent resistance value discrepancies from affecting color output. If the problem persists, contact our professional customer support team for further assistance.

Short Lifespan

• Problem Description: LED screens experience shorter lifespan due to aging of LED components.
• Analysis Causes: Contributing factors may include operating temperatures above standard levels.
• Solution:
  • Adhere to standard operating conditions to prevent excessive heat buildup, avoiding environments with high humidity or temperature fluctuations.
  • Regularly perform preventive maintenance by replacing aging components and inspecting connection lines. Utilize professional testing tools for early fault detection.

Flickering or Blur Effect

• Problem Description: The displayed image exhibits flicker, motion blur, or other fuzzy effects.
• Analysis Causes: Possible reasons include faulty timing controller circuits, overheating of drivers, or defective connection lines.
• Solution:
  • Inspect the timing controllers and power supplies to ensure they operate within normal parameters. Use a scope to measure voltage and current signals for identifying anomalies.
  • Clean any dirt on connection lines to eliminate resistance value discrepancies. Replace damaged connections as necessary.

Blue Light Display Issues

• Problem Description: In blue light mode, colors or brightness may appear abnormal.
• Analysis Causes: Potential issues involve the color adjustment module failing to properly drive blue LEDs effectively.
• Solution:
  • Confirm that the color settings in the adjustment module are correctly configured and compatible with the power supply unit.
  • Use specialized tools to calibrate the output of blue LED chips.

Power Overheating or Flash Burn

• Problem Description: Power supply-induced heating is severe, potentially leading to flash burn occurrence.
• Analysis Causes: High-power LED screens require stable voltage and current regulation for proper operation.
• Solution:
  • Implement a steady-state power supply or incorporate a voltage limiter/capacitor circuit. Add cooling components like heat sinks while ensuring effective ventilation.

Black Shadows on the Screen

• Problem Description: Parts of the screen display black shadows, affecting overall visual impact.
• Analysis Causes: Possible reasons include broken connection lines or short circuits in signal lines.
• Solution:
  • Utilize a scope to thoroughly inspect and test all signal lines for integrity. Clean any dirt or debris on connection lines to prevent resistance value anomalies.

User-Defined Settings Issues

• Problem Description: Incorrect settings during initial configuration may result in display malfunctions.
• Solution:
  • Provide detailed default configurations and adjustment guidelines within the product packaging. Include user manuals with comprehensive information on setting up LED screens correctly.

Other Issues

• Problem Description: Various other issues, such as failure to turn on or inconsistent image quality, may arise despite proper installation.
• Analysis Causes: May include manufacturing defects in LED components, improper power supply configuration, incorrect settings for external control units, or software-related malfunctions.
