When using the automatic mobile LED display, sometimes half of the screen will be bright and half will be dark due to improper installation or other reasons. When this happens, we must understand the specific reasons that cause half of the LED display screen to be dark and half to be bright, and then analyze and troubleshoot through reasonable steps to solve the problem from the source. So do you know how to deal with the situation where the automatic mobile LED display is half bright and half dark?Below, ONUMEN will introduce it to you:
Possible causes and solutions for half brightness and half darkness of the automatic mobile LED display:
First, check and confirm whether the serial port cable used to connect the controller is loose or disconnected. If the automatic mobile LED display turns black during the loading process, it is likely that the screen turns black due to communication interruption caused by loose communication cables. Do not mistakenly think that the screen body cannot be loose if the line is loose. Please check first, as this is important for quickly solving the problem.
Check and confirm whether the LED display screen is tightly connected to the HUB distribution board connected to the main control card, and whether it is inserted correctly.
Ensure that all hardware, including the control system, is powered on correctly. Check if the power indicator is flashing and if there is any power failure. It is worth noting that the use of inferior power supplies often leads to the phenomenon of half brightness and half darkness in the automatic mobile LED display.
If several boards in a row are not bright vertically, check if the power supply for this column is normal.
If several boards in a row are not bright horizontally, check if the connection between the normal unit board and the abnormal unit board is connected or if chip 245 is normal.
If there is a clear boundary between the software settings and the lamp tube of the automatic mobile LED display, it is likely that it is caused by software or settings. If there is a uniform transition between the two, it may be a lamp tube problem.
In conclusion, these are the possible causes and solutions for half brightness and half darkness of the automatic mobile LED display. When this situation occurs, we should investigate and locate the most likely cause one by one for quick resolution. If it is due to hardware failure or cannot identify the problem, please contact the manufacturer for after-sales service to obtain better technical support.
