What are the maintenance methods of LED display?

So what are the inspection methods of LED display and how should customers do well in the inspection of LED display?

1. LED display resistor detection method: for the LED display screen resistor detection method, we need to adjust the multimeter to the resistor, first detect a point to ground resistance value of a piece of normal circuit board, and then test another same circuit board of the same point to detect whether it is different from all normal resistance values. If not, you will know the scope and phase of the LED display screen problem On the contrary, they ignore it.

2. LED display screen working voltage detection method: LED display screen working voltage detection is to adjust the multimeter to the working voltage, detect the abnormal power supply circuit a point of the working voltage to the ground, is more normal than before, so that it can be convenient to identify the problem.

3. LED display short circuit detection method: LED display short circuit detection method is to switch the multimeter to the short circuit detection gear, so as to detect whether there is a short circuit condition. If there is a short circuit, it should be handled immediately. The short circuit condition of LED display is also a common fault of LED display module. Továbbá, the short circuit detection should be carried out under the condition that the power supply circuit is turned off, so as to avoid damaging the multimeter.

4. LED display voltage drop detection method: the LED display voltage drop detection method is to adjust the multimeter to the diode voltage to carry out the downscaling detection. Since all the IC of the LED display screen is composed of many modules, when there is a current amount on a pin, there will be current on the pin. Under all normal conditions, the voltage drop on the IC pin of the same model and specification is similar.

In view of the above several types of LED display screen maintenance methods, we can remember it, not in the case of regular implementation of detection, to prevent the damage of LED display, but also very good to increase the life of your LED display. In this way, it can not only prolong its use time, but also save the following extra expenses and budget expenses. Since some LED display manufacturers have only one to two years of after-sales maintenance service, after this time of after-sales maintenance, if the maintenance is carried out again, there will be additional charges.
