What should I do if the LED display module fails? When it comes to night scenes, LED displays are essential. With its natural and delicate pictures and bright colors, it has become a shining presence in the night scene and a landmark building in a city. The LED display has a wide range of functions, as a decoration or advertising campaign, it can achieve unexpected results. In addition, the original design of the screen is fashionable and novel, and the structure of LED display products is diversified. LED tunnel display screens, LED heterosexual screens, and LED transparent screens can successfully attract tourists' attention and bring a visual feast.

  The LED display not only drove the night travel economy, but also reaped business opportunities in the night travel economy. At present, with the continuous development and innovation of LED display equipment technology, more and more novel products have begun to appear. In entertainment, LED floor tiles can be used to display, which can improve the interaction between people in leisure and entertainment; instead of traditional firework pollution, the use of LED devices that can change colors at will can also make people excited; various LED displays can replace traditional devices, Surprise tourists.

  Topsun Optoelectronics actively pays attention to industry trends, insists on using the most advanced and scientific solutions to complete the construction of each project, and provides users with the highest quality products and the most professional services.

  No matter how high the cost and quality of the outdoor led display is, it will inevitably fail in the outdoor wind and rain, such as broken lights and partial black screens. So what should I do if the LED display module fails? Why does the module appear color cast? You will understand after reading the following.

  1. What should I do if the LED display module fails?

  Under normal circumstances, the main failures of LED display modules are as follows:

  (1) Large area black screen phenomenon of led display

  Solution:

  1. Check whether the power is on.

  2. Check whether the cable is in good contact.

  (2) Dead pixels (out of control points) appear on the led display

  1. Frontal maintenance: Use a screwdriver of the corresponding model to remove the screws of the fixed mask, remove the mask, and replace the lamp. After the lamp replacement and gel sealing are completed, restore the original mask and tighten the screws.

  2. Back maintenance: Use a screwdriver of the corresponding model to remove the screws from the back, unplug the signal cable, and perform maintenance on a single module in accordance with the front maintenance method to replace lights or overhaul others.

  (3) The led display module does not light up, and a black screen appears on the module

  1. Check whether there is a problem with the power supply.

  2. Check whether the transmission cable is in bad contact. If the color of the whole module is chaotic or inconsistent (but there is signal input, there is a correct picture), re-plug the cable, or replace the tested cable.

  3. Check if there is any problem with the interface of the PCB board.

  2. What is the reason for the color cast of the module?

  1. Production process

  After the wave soldering of the led module, the position of the led has been fixed, and it should not be moved at this time. However, because many companies do not have the protection conditions, they often collide and bend the LED lights in the process of testing, repairing, soldering pin headers, aging and transferring. Then perform the so-called whole line before the glue is poured, which will easily cause the lights on the LED display to fall irregularly and cause the color cast of the module.

  2. Power supply problem

  When designing LED display screens, it is impossible to know what materials to choose (including power supply selection and consumption), and there is a problem with the power supply system, which leads to uneven power supply of the LED modules.

   3. Control system, control IC

  Because led display manufacturers do not have the design, development, testing and production capabilities of led display control systems and control ICs. Of course, the production screen cannot be guaranteed, and the only thing to do is to adjust the parameters.
