Like traditional electronic products, in order to make the LED display screen last longer, it is not only necessary to pay attention to the method during use, but also to maintain the LED display screen. With the wide use of LED display screens, there are more and more use problems, and the influence of various objective and subjective factors has caused problems such as shortened lifespan of LED display screens, inability to display normally, and black screens. The following introduces some precautions and maintenance methods for LED display.

  1. Routine maintenance and maintenance of the main control computer: The computer is generally placed in the control room. In order to ensure the stability of the display screen broadcast program and good display effect, we should often perform the following maintenance on the main control computer.

1. Keep the control room environment clean, and regularly remove dust from the computer and peripheral equipment, because dust will contaminate important components such as computer keyboards, disks, monitors, and host circuit boards, which may cause major failures.

  2. When the computer is working, it will emit a lot of heat. If the heat dissipation is not good and the indoor temperature is too high, it is easy to cause the computer to crash and other failures. Long-term use will reduce the service life of the main control computer. Therefore, attention should be paid to indoor ventilation.

3. If the ambient temperature is high (such as hot summer), a fan should be installed in the control room, and air conditioning equipment can be installed if conditions permit. The temperature should be maintained at 10°C to 35°C, and the relative humidity should be 30%-80% Try to avoid the computer working in a high temperature and high humidity environment.

4. Regularly check the hardware and peripheral equipment of the computer, such as the graphics card, whether the sending card is loose, whether the DVI cable, the RS232 serial port cable is loose or damaged, etc., and the problem should be eliminated in time.

5. Regularly conduct anti-virus treatment on the computer, especially those who can access the Internet should install anti-virus software, and regularly upgrade the playback software to ensure that the version of the playback software is up to date.

  2. Notes on changes and changes in the control part

1. The power lines of the computer and the control part should not be reversely connected to zero and fire, and should be connected in strict accordance with the original position. If there are peripherals, after connecting, you should test whether the case is live.

2. When moving control devices such as computers, check the connection cables and control boards for looseness before powering on.

3. The position and length of communication lines and flat connecting lines cannot be changed at will.

4. If any abnormality such as short circuit, tripping, burning wire, and smoke is found after moving, the test should not be repeated, and the problem should be found in time.

3. Precautions for software operation and use

1. Software backup: WIN2003, WINXP, applications, software installers, databases, etc. It is recommended to use the "one-key restore" software, which is easy to operate.

2. Proficient in installation methods, original data recovery and backup.

3. Master the setting of control parameters and the modification of basic data presets.

4. Proficient in using programs, operations and editing.

5. Regularly check for viruses and delete irrelevant data.
