In the process of providing LED display for many years, Chip Optoelectronics has summarized some problems in LED display screens, in which the black screen phenomenon of LED display screens is a big problem for users. To solve the problem of black screen LED display is actually very simple, the following LED display manufacturers to answer in detail for you.
In the course of the use of restraint systems, we occasionally encountered the phenomenon of a black screen on the LED display. The same phenomenon is caused by various disagreements, and even the darkening of the emerging screen may be caused by differences or differences. For example, the moment when it is roughly on power-on is black, and it is roughly blackened during the loading process, and it is roughly blackened after the completion of sending. If you encounter this phenomenon, please refer to the following aspects to resolve the "failure" decisively.
1. Please check and confirm whether the 50-core cable between the adjacent spirit letter card and HUB distribution board is loose or inserted.
Second, check and re-confirm the serial cable used to connect the controller is loose or off phenomenon. (If it is black in the loading process, it is very rough because it was caused by the original reason, that is, because the communication line is contained in the communication history and contained, the screen is black. Do not feel that the screen is not moving, the line is not loose. Please check it out, which is very serious for you to solve problems quickly.)
Third, if your display screen interface definition and the supplied HUB board are not in the same room, there will be a black screen phenomenon. Please re-check whether your jumper is moving, open circuit or short circuit. If you feel that you have already matched the ABCD signals, please check whether the OE signals are connected correctly.
Fourth, please ensure that all the hardware, including the restraint system, has been properly powered up. (+5V, do not connect, connect wrong)
5. Check and confirm whether the LED display screens connected to the main control card and the HUB distribution board connected to the main control card are connected closely and whether the connection is reversed.
According to the above method, the black screen problem of the LED display can be easily solved. At the same time, the daily maintenance of the LED display must be done well. Only in the prevention, focus on routine maintenance can better protect the LED display.
