How to repair a broken LED display screen?

How to repair a broken LED display screen? Introduction to faults and repair methods of indoor LED display screens.

1. There are scattered non flashing lights in the entire screen, also known as small spots, bad lights, or dead lights. (If it is not a localized occurrence, and if it is within the scope of repair rate, it will not significantly damage the essential effect of the visual display.)

2. When the LED display screen is powered on, there is a jump box, and the continuous application is like this. (Check the way to open and close the power supply, especially the polarity power plug interface, and inquire if there is any contact, as well as the connecting head of the power supply main opening and closing. Another point is that there is no need for metal objects to fall into the display screen.)

3. Each line of the LED display screen displays extreme visual effects, with flickering colors. (Conduct a preliminary inspection of the wooden board at the extreme position of emergence, checking whether the wire harness is loose and whether the wooden board wire harness socket is damaged. If there is no difficulty in disassembling and replacing the wire harness or repairing the wooden board)

4. A large video cannot be displayed on the LED screen, it is all black. (Firstly, consider the difficulty of opening and closing the power supply. First, check the difficult wooden board to see if the power supply is broken and there is no power. Check if the wiring is loose and if the data signal has not been transmitted. If there are any issues, it may be that the responsible card is damaged. If you eliminate them one by one, you can find a treatment plan.)

5. When playing videos or photos on LED display screens, the computer controls the entire display area, but sometimes the screen freezes or goes black. (Usually it is a collection line product quality problem, and video transmission data becomes lost before it becomes a black screen card problem. When replacing a collection line with better quality, a certain piece of wood on the LED display screen appears with flashing grids, mixed colors, and parallel continuous lights, which are extremely visible. If it is difficult to replace a wooden board, only the one that appears extremely visible can be replaced. The screens installed against the wall in the room are usually magnetically attracted, and using some force to remove the wooden board can only be replaced.)

7. The LED display screen has a whole area of wooden boards that are extremely visible, with orderly patterns flashing. (Usually, it is difficult to take on responsibility cards. It is necessary to verify which region is monopolized by which responsibility card, and replacing the responsibility card can alleviate poverty.)

8. The connection between the computer collection cable and the LED display collection cable is good. The mobile app indicates that “no display screen style is found”, and even the LED display screen may have the same effect as ordinary photos and videos. However, the software supports the upload of statistical data, such as color upload, which does not win. (Usually, if there are difficulties in uploading, replacing the upload card can clean it up)

9. The dialogue box of the LED display screen playback software appears ordinary, but the interface on the display screen is messy, separated or divided into several independent dialogue boxes to display similar interfaces. (It is difficult to support the software, and once it is properly set up, it can only be cleaned up.)

10. LED display screen simultaneously displays full screen on the computer desktop. (If it weren’t for the LED video cleaner, this effect wouldn’t have been worth it; with the video cleaner, you can arrange the interface area that needs to be displayed on the LED display screen at the same time.)
