LED advertising screen is not just a simple display product like TV, but integrates optics, electronic application, mechanics, aesthetics, etc. During the application process of LED advertising screen, it is inevitable that there will be some failures, or loose wiring, or software operation. Incorrect, below we summarize the situations that often occur in the daily use of LED advertising screens in order to eliminate them in time. Let's first analyze the composition of the LED advertising screen, which is mainly composed of LED modules, LED control cards, LED power supplies, short cables, long cables, 5V power cables, 220V box-through power cables, strong cables and 380V strong electricity, It is composed of distribution box, video processor, power amplifier, heat dissipation, structure and other parts.

If there are regular large blocks of black on the LED advertising screen, you can check whether the software partition is covered, then check whether the network cable and power cord are loose, and check whether the power supply is supplied again.

The second situation: a row of LED advertising screens flickered in the past, similar to the situation of garbled characters. This problem can be judged as the signal supply of the single-row LED module is not normal. Jump to the problematic LED module. If it displays normally, it proves that this LED module is normal. Then insert the cable to the right side of this module to check whether the previous module is normal. If it is also normal, then Just replace the short cable between two LED modules. If a module is found to be abnormal, it can be determined that the driver chip of this LED module is faulty, and it can be sent back to the LED advertising screen manufacturer for repair or on-site replacement.
