LED full-color display correct use and routine maintenance is very necessary, not only to reduce the failure rate of the display, but also to extend its service life, the following is LCF engineers edited on the use of LED display and routine maintenance notes operation manual, and now share it with you:
First, switch LED electronic display screen precautions:
1,switching order: when turning on the screen: first turn on the screen, then turn on the screen. Close the screen: first shut down the screen, then shut down the computer (first shut down the computer does not shut down the display, will cause the screen to appear high brightness, burned lamps, the consequences are serious.) Open the LED screen body (the screen body will have regional flicker instantly, indicating that the screen body is energized), open the computer, be sure to ensure that the graphics card is set up correctly (incorrectly there will be no display screen, i.e., the black screen), open the control software, basic pixel dimensions and display area settings (this setup does not affect the display of the LED display screen)
2, switch the LED screen interval should be greater than 5 minutes.
3, the computer into the project control software, before the screen can be opened and energized.
4, avoid opening the screen in the all-white screen state, because at this time the system has the largest impact current.
5, avoid opening the screen in the runaway state, because this time the system's impact current is the largest.
A computer does not enter the control software and other programs;
B The computer is not powered on;
C control part of the power supply is not turned on.
6. When the ambient temperature is too high or the heat dissipation conditions are not good, care should be taken not to open the screen for a long time.
7. Electronic display body part of a line of very bright, should pay attention to timely shut down the screen, in this state should not be a long time to open the screen.
8. The power switch of the display is often tripped, the screen body should be checked in time or replace the power switch
9. Regularly check the firmness of the connection. If loose phenomenon, pay attention to timely adjustment, re-enforcement or update the hanging parts.
10. According to the LED large screen display screen body, control part of the environment in which the situation, to avoid insect bites, if necessary, should be placed in the anti-rodent medicine.
Discover the problem:
Check whether each wiring method is correct, including, the connection of the strong electricity part (the weak electricity part has been tested and completed in the production enterprise), whether the signal connection is correct, mainly for the system receiving card input and output direction is correct, there is a direction schematic on the receiving card.
Whether the system connection is correct (please refer to the system connection instructions)
Whether the installation of the computer software part has been completed, including the setting of the graphics card (please refer to the instructions for the setting of the graphics card) and the installation of the control software.
Notes:
1. Observe the operation steps in the LCF User's Manual;
2, moisture, humidity requirements are: the maximum operating temperature, LED display should be less than 92% relative humidity
3, the temperature is appropriate, the temperature requirements are: working environment temperature -20°C ≤ t ≤ 80°C Storage environment temperature -40°C ≤ t ≤ 60°C
4, Power supply should meet the requirements
LED display power supply voltage: 220V ± 10% Frequency: 50HZ ± 5%
Safe and reliable earth contact, ground and zero line isolation is reliable, access to power away from high-power electrical equipment.
Second, the control part of the change, change notes
1, computer, control part of the power line zero, fire can not be reversed, should be strictly in accordance with the original location of the plug. If there are peripherals, after the connection is completed, the case should be tested to see if it is electrified.
2, move the computer and other control equipment, power should first be checked before connecting the line, the control board has no loose phenomenon.
3, can not change the position and length of the communication line, flat connecting line.
4, after moving, such as short circuit, tripping, burn line, smoke and other abnormalities, should not be repeatedly energized test, should be timely to find the problem.
Three software operation precautions
1, software backup: WIN7, WINXP, applications, software installers, databases and so on. It is recommended to use “one key restore” software, easy to operate.
2, proficiency in the installation method, the original data recovery, backup.
3, master the control parameters of the settings, the basic data preset modifications
4, skilled use of programs, operations and editing.
5, Regularly check the virus, delete irrelevant data
6, non-specialized personnel, please do not operate the software system.
