LED displays are now widely used in various fields, and are favored by users for their seamless splicing, energy saving, and delicate image quality. However, some minor problems may occur during use. Below are some common problems and solutions collected by us.1. Problem: A certain area of the LED screen displays abnormally, for example, showing a jumbled mess of flashing colors.
Solution: This is usually a receiving card problem. Check which receiving card controls that area, and replacing the receiving card can solve the problem.
2. Problem: A row of the LED display shows abnormal, flashing colors.
Solution: Start checking from the abnormal board. Check if the ribbon cable is loose or if the board's ribbon cable connector is damaged. If there is a problem, replace the ribbon cable or the faulty board.
3. Problem: There are scattered unlit LEDs on the entire screen, also called black spots, bad LEDs, or dead LEDs.
Solution: If it's not a large area of failure, and within the acceptable failure rate, it generally does not affect the display effect.
4. Problem: The LED display trips the circuit breaker when powered on, and this happens repeatedly.
Solution: Check where the power line is short-circuited, especially check if the positive and negative power line connectors are touching each other, and also check the connectors on the power switch; also, make sure no metal objects have fallen inside the screen.
5. Problem: A certain board on the LED display shows flashing squares,杂色 (jumbled colors), and several consecutive LEDs display abnormally.
Solution: This is a board problem. Simply replace the abnormally displaying board. Indoor screens are usually installed on the wall with magnets; just pry off the board and replace it.
6. Problem: A large area of the LED display is not displaying anything, it's all black.
Solution: First, consider power transmission problems. Start checking from the problematic board to see if the power switch is broken or there is no power, check if the ribbon cable is loose and the signal is not being transmitted, and then consider the possibility of a damaged receiving card. Eliminating these possibilities one by one will help find the solution.
7. Problem: When the LED display is playing videos or images, the computer software displays normally, but the screen sometimes freezes or shows a black screen. Solutions: This is usually a problem with the network cable quality; data loss during video transmission causes the black screen and stuttering. Replacing the network cable with a higher-quality one should solve the problem.
8. Problem: Want the LED display to synchronize and display the entire computer desktop screen.
Solution: This function cannot be achieved without an LED video processor; with a video processor, you can adjust the display area on the video processor to synchronize the desired image area to the LED screen.
9. Problem: The LED display software window shows normally, but the image on the screen is distorted, misaligned, or divided into multiple windows displaying the same image separately.
Solution: This is a software setting problem; re-configuring the software settings correctly should solve the problem.
10. Problem: The network cable between the computer and LED screen is properly connected, but the software displays "Large screen system not found," even though LED screen can play pictures and videos normally. However, all data sent by the software fails, such as brightness adjustment failing.
Solution: This is usually a problem with the sending card; replacing the sending card should solve the problem.
