What are the maintenance methods for LED displays? No matter how good the quality is, when a product has to be overhauled, its life span is not only the quality of the product itself, but maintenance is also an important key. LED displays appear just like any other product. The problem is reasonable. What we can do is to better discover it before the problem comes, and do the repair work as early as possible. So what are the maintenance and inspection methods of LED display, and how should users do the inspection work of LED display?

1. LED display resistance detection method

For the resistance test method of the LED display screen, we need to adjust the multimeter to the resistance range, first check the resistance value of a certain point of a normal circuit board to the ground, and then test the same point of the same circuit board to test the normal resistance value Whether there is a difference, if there is a difference, you will know the scope of the display problem, otherwise, ignore it.

2. LED display voltage detection method

The voltage detection of the LED display screen is to adjust the multimeter to the voltage range to detect the ground voltage at a certain point of the circuit that is suspicious and problematic, and compare it with the previous one, so that the problem can be easily determined.

3. Screen short circuit detection method

The LED display short-circuit detection method is to set the multimeter to the short-circuit detection block, so that it can detect whether there is a short-circuit phenomenon. If a short circuit is found, it should be solved immediately. The short circuit of the display is also the most common LED display module failure. in addition! The short-circuit detection should be performed when the circuit is powered off to avoid damage to the multimeter.

4. LED display pressure drop detection method

The LED display voltage drop detection method is to adjust the multimeter to the diode voltage for the drop detection gear, because all the ICs of the display are composed of many single components, so when there is a current on one of its pins, it will be There is a voltage drop on the pin. Under normal circumstances, the voltage drop on the IC pins of the same model is similar.

For the above four kinds of LED display maintenance methods, we can keep them in mind, and carry out inspections at irregular times to avoid damage to our display screens, and can also extend the life of our LED display screens. In this way, it can not only lengthen its use time, but also save the following unnecessary budget expenditures. Because some LED display manufacturers only provide after-sales service for one to two years. After this after-sales maintenance time, if you perform maintenance again, you will be charged an additional fee.
