In the process of using the automatic lifting LED display, due to improper operation and installation or other reasons, sometimes the automatic lifting LED display is half bright and half is not bright. When this happens, we must understand the specific reasons that cause half of the LED display to not light up and half to light up, and then analyze and troubleshoot through reasonable steps to solve the problem from the source. So do you know what to do with the automatic lifting led display half on and half on not?The following is an introduction to Weishay:
Possible reasons and treatment methods for automatic lifting LED display half bright and half not lit:
First, the line is loose.
1) First, check and confirm whether the serial port cable used to connect to the controller is loose or has fallen off. If the automatic lifting LED display has turned black at the beginning of the loading process, it is likely that it is interrupted due to the loosening of the communication line during the communication process, so the screen becomes black, do not mistake it for the screen body is not moving, the line is impossible to loosen, please check it first, but this is important to solve the problem quickly.
2) Check and confirm whether the HUB distribution board connected to the automatic lifting LED display and the main control card is tightly connected and reversed.
Second, the power supply problem.
Make sure that all hardware, including the control system, is powered on correctly. It is worth noting that the use of inferior power supply usually leads to the phenomenon that the automatic lifting LED display is prone to half of the light and half of the light is not lit.
Third, the LED unit board connection problem.
1) If the longitudinal direction of several boards is not lit in a row, check whether the power supply of this column is normal.
2) The horizontal direction of several boards in a row is not bright, check whether the cable connection between the normal unit board and the abnormal unit board is connected;Or whether chip 245 is normal.
Fourth, software settings or lamp problems.
If there is a clear demarcation between the software settings or the lamp tube of the automatic lifting LED display, the possibility of software or setting is large. If there is an even transition between the two, it may be a lamp problem.
To sum up, it is the possible reasons and treatment methods for the automatic lifting of the LED display half on and half on the non-light, when this situation occurs, we should investigate one by one from the reasons that are more likely to be located. If it is due to hardware failure or the problem cannot be confirmed, please contact the manufacturer for after-sales service for better technical support.
