The application of LCD splicing has been popularized in various industries in our lives. Now we analyze in detail the common problems and solutions we encounter in the daily use of LCD splicing screens. Signal interference is the installation and use of LCD splicing screens. Often encountered in the process, and now we do some system analysis and troubleshooting on the more common signal interference LCD splicing screen:
Signal interference mainly caused by these kinds of situations: caused by the power supply system's power supply; space radiation interference introduced by the transmission line; short circuit of the video cable's core wire and shielded network, fault caused by open circuit; the quality of the video transmission line is not good; near the system There are strong sources of interference.
Analysis of signal interference for splicing screen
If we can confirm that the signal interference is caused by the power supply system's power supply after troubleshooting, then we can basically solve the entire LCD splicing screen using clean power or online UPS power supply. The space radiation interference introduced by the transmission line, one of the solutions to this situation is to understand the surrounding environment when the system is established, try to avoid or stay away from the radiation source; another approach is to the front-end when can not avoid the radiation source And the center equipment strengthens the shielding, uses the steel pipe and the good grounding to the transmission line pipeline.
The faults caused by the short circuit and open circuit of the video cable's core wire and shielded network often appear on the BNC connector or other types of video connectors. When this kind of fault phenomenon occurs, the LCD video wall will not be the entire system. Signals from all directions are problematic, and they only appear on the number of bad connections. As long as the connectors are checked one by one, they can be solved. There is a strong source of interference near the system. This can be judged through investigation and understanding. If this is the reason, the solution is to strengthen the shielding of the camera, as well as to ground the pipeline of the video cable.
If the detection is not caused by the above factors, then this time you need to contact the LCD splicing screen manufacturers to solve, the general formal manufacturers have a professional after-sales team can arrange for technical staff on-site inspection and maintenance in the shortest possible time; users do not Privately open the detection of LCD splicing screen, so it is extremely easy to cause damage to the LCD splicing panel due to improper operation.
