LED Display Screen Maintenance Professional Technical Knowledge
LED display screen maintenance professional technical knowledge, full-color LED display screen installed, also debugged, used to have problems? What caused this? In the course of using, there will inevitably be various problems. How to maintain the ability to reduce the problem?
First, LED display screen hardware problems;
1.1, LED display screen is also known as (word-walking screen), the whole screen visible defects, do not show fonts, or appear incomplete.
1.2, the screen often has bright spots (diode).
1.3, the display screen often does not appear font.
1.4, the LED display control card is broken.
1.5, the power is burnt out.
Two, software problems
1.1. Users will not reinstall the software without the LED display screen or the LED software and settings parameters after reinstalling the system; 1.2, LED display screen operation software partial file loss, resulting in upload update information.
1.3, the user has changed the parameters of LED operation software (the parameters of each service hall are different).
1.4 The user himself installed the LED operation software, did not "use the serial port to send and receive data" in front of the check off;
1.5. LED operation software prompts that the latest version can be used normally after promotion.
1.6, a simple understanding of "Liyan SCL2008 display operation";
2, IP address expansion of the closure Hall
2.1, can the new IP address of the display screen be fixed and fixed? There are multiple network segments in a service hall.
2.2, the service hall is more IP network segment, no more LED display screen IP segment.
2.3, the display screen new IP address has been bound, if there is a change in the LED display screen IP, must inform the maintainer.
Three, simple troubleshooting
1. There are three kinds of unsuccessful upload and update data: first, when the upload data is unsuccessful, turn off the LED power supply for 10 minutes and let the LED display stop running temporarily. After 10 minutes, turn on the power supply and upload the data again, you can send the data normally. Reduce the failure rate and facilitate maintenance.
1.1. Long-term power supply has not been turned off to a certain extent, LED display is in a state of crash, is also the reason for unsuccessful upload update.
1.2, the network is blocked, the network IP address and the network segment are inconsistent, leading to the failure of uploading.
1.3, the subnet mask is not consistent with the subnet mask of the LED display.
1.4, the IP gateway of LED display is not consistent with the existing gateway.
1.5, the network is blocked, there may be an interface between the network cable or where the crystal head is loose, and the contact is bad.
