Receiving card failure is a common problem in LED display systems. Its common causes mainly include the following aspects:
1. Power supply problem: The receiving card may fail due to unstable power supply voltage or poor contact of the power supply line, resulting in failure to receive and process signals normally.
2. Signal transmission problem: Quality problems or poor connection of signal lines (such as DVI, HDMI, etc.), as well as long or poor quality network cables, may affect the normal transmission of signals, thereby causing receiving card failure.
3. Equipment compatibility problem: Poor compatibility between the receiving card and the sending card or other intermediate transmission equipment may also cause the receiving card to fail to work properly.
4. Equipment aging or damage: As an electronic device, the receiving card may age or be damaged after long-term use, thus affecting its performance and stability.
5. Software or setting problems: Software program errors or improper settings of the receiving card, such as driver loading errors, inconsistent configuration files, etc., may also cause the receiving card to fail to work properly.
For the above reasons, receiving card failures can be prevented and resolved by checking the power connection, replacing the signal line, ensuring equipment compatibility, regularly maintaining and replacing aging equipment, and adjusting software settings.
