  •      With the advent of the information age, the rapid development of computer multimedia technology, the universal application of network technology, the display system based on digital and high-definition large screens in various places such as command center, performing arts center, conference center, security center, radio and television station, etc. The increasing use of applications has become an important guarantee for the normal operation of these places.
  •  
  •      LED display applications are becoming more and more widely used, and we will encounter some display failure problems more or less during use. So how to quickly and accurately handle system failures in daily applications, ensure that the system is running well, and provide efficient, timely and reliable service guarantees, is the main purpose of this paper.
  •  
  •      So, what are the troubleshooting and solutions for touch screen systems? KONWHAI Xiaobian answers for you.

  • Display system troubleshooting and solutions

  •   Display system troubleshooting and solutions:  
  •  
  •      A typical large-screen display system generally consists of a signal input subsystem, a signal exchange and processing subsystem, a signal output subsystem, and peripheral equipment. In practical applications, large-screen display systems often have black screens, blue screens, flower screens, image blurs, ghosting, picture jitter, and sudden failure of a certain signal to display, thus affecting the overall system display.
  •  
  •      Due to the complexity of the system composition, any of these links may cause the above-mentioned faults. Therefore, after a fault occurs in daily applications, how to quickly and accurately dispose of it to ensure the normal operation of the system becomes the key to improving the level of guarantee service.
  •  
  •      The machine has vertical lines, vertical bands, black screens, flower screens, etc.; touches can cause problems such as broken wires, jumpers, and unrecognizable. Cause of the fault: The voltage is abnormal or the humidity of the air is too large, which damages the board. The screen display is incomplete and the screen is shifted.
  •  
  • Approach:
  •  
  •      1. Properly use and maintain the multimedia LCD integrated machine according to the instructions;
  •  
  •      2. Improve the environment of the multimedia LCD integrated machine, such as increasing the voltage V of the integrated machine, the current I protection system, reducing the environmental humidity, etc.;
  •  
  •      3. If the humidity is too high in rainy days, the machine will be easily damp and should not be turned on less than 8 hours per day;
  •  
  •      4. Whether the resolution displayed by the computer is compared according to the ratio set by the large-screen menu, such as 16:9; 4:3; point-to-point;
  •  
  •      5. Screen shift to see if there is a problem with the access signal line such as VGA or HDMI, and then set the normal ratio of the large screen menu;
  •  
  •      6. The color cast should detect whether there is a problem with the access signal line such as VGA or HDMI, or the menu color on the large screen changes, or the factory settings are enough to be changed;
  •  
  •      The above is about the troubleshooting of the display system and the solution. If the user purchases the LCD advertising machine, the above steps can be used to solve the problem when the display system is faulty during use. I want to know more multimedia advertising machines.
