What are the abnormalities of general indoor LED displays, and how to repair them if they are broken? Common faults and maintenance methods of indoor LED display. Indoor LED display manufacturers install and debug on-site and deliver them to users. Any abnormal situation that occurs is the problem with the user. According to the feedback of previous users, there are generally the following Situation and maintenance methods:

1. The entire screen is a piece of light bulbs, also called black spots, broken lights, and dead lights.

2. There is a jump box when the indoor LED display is powered on, and the same is true for repeated operations. (Check the short circuit of the power line, especially the positive and negative power cord joints, to see if there are contact surfaces and contacts on the power switch; in addition, do not let metal objects fall into the screen)

3. The indoor LED display shows a single line of abnormality, which flashes and disappears. (Check from the abnormal position of the board, check whether the cable is loose, whether the cable interface of the board is damaged, if there is any problem, replace the cable or the defective board)

4. A large area of the indoor LED display cannot be displayed, all of which are black. (First consider the power transmission problem, start from the problem board, check whether the power switch is off, whether the power is on, check whether the cable is loosened, the signal has not been transmitted, and then check whether the receiving card is damaged, eliminate them one by one, and find out the solution Method)

5. When the indoor LED display screen is playing video or pictures, the computer software display area is normal, but the screen sometimes freezes or black screen.
