What are the common LED screen problems and their quick solutions?
1.The screen won’t turn on at all
Problem: The display won’t turn on or has no power.
Solution: First, check the power source to ensure proper connection. Inspect the circuit breaker, fuse, and cables for any issues. If the power supply is faulty, replace it with a new one.
2.The image looks blurry or not sharp
Problem: The image displayed is distorted, blurry, or of low quality.
Solution: Check the signal input to ensure the source resolution matches the display’s resolution. Also, inspect cables for damage or loose connections.
3.Parts of the screen look brighter or darker than others
Problem: Some areas of the display have uneven brightness or inconsistent colors.
Solution: Perform a calibration and adjust the brightness and color settings. If the issue persists, check for any damage to the LED modules or connectors.
4.There are tiny black dots that won’t go away
Problem: There are pixels on the display that won’t light up, showing as black dots.
Solution: Dead pixels are typically caused by faulty LED lamps. Replace the damaged modules or attempt to fix dead pixels using software.
