LED display and LED outdoor full-color display are always unavoidable that bright lines appear in the process of use. What causes it? How to check and troubleshoot problems? You will understand after reading the following!
Reasons for 'bright lines' appearing during the use of the led display:
1. The quality of the product is not good enough. Don't try to buy cheap products with low prices and poor quality when buying.
2. The voltage is unstable, causing leakage.
3. Improper operation method, man-made operation error, affect the effect of the display screen.
How to check and troubleshoot a 'bright line' fault during the use of the led display?
First, determine whether the power supply is damaged and whether it can be used normally. Because a power supply controls several unit boards at the same time. You can measure whether the output voltage is between 4.9~5.5v. If it is not in this range, it is likely that the power supply is broken.
Second, check if the control card is in normal use. Turn on the power first and check whether the indicator LED Light module of the control card is on; if it is not, check whether there is 5V power supply and whether the LED electronic screen can display the content. If it can display the content, it means that the control card display content function is good. ; Then use the control card software to find the control card. If it can be found, it means that the function of the control card sending content is good; if it can’t be found, check whether the communication line is connected. If it is connected, then It is very likely that there is a problem with the card. As long as these two functions are good, the control card is good, otherwise the control card must be replaced.
Third, check whether the unit board is good. The signals of the LED display are all inputs transmitted from one board to another. So if there is a problem with one board, it will affect the back board. So check whether the unit boards are normal one by one.
