No matter how good the quality of a product is, it can be overhauled. In addition to the quality of the product itself, overhaul and maintenance is also an important key to the length of its life. It is reasonable for the LED Display to have problems like any other product. We can do it. What is achieved 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 for LED Displays, and how can customers do the inspection work for LED Displays?
1. Display Screen Resistance Detection Method
For the resistance inspection method of the display screen, we need to adjust the centimeter to the resistance range, first check the resistance value of a certain point of a normal circuit board to the ground, and then check the same point of the same circuit board to test whether the resistance value is normal If there is a difference, you will know the scope of the display problem, otherwise, ignore it.
2. Display Screen Voltage Detection Method
The voltage detection of the LED Display screen is to adjust the centimeter to the voltage range to detect the ground voltage at a certain point of the circuit with suspicious problems, and compare it with the previous ones, so that the problem can be easily determined.
3. Display Screen Short Circuit Detection Method
The short-circuit detection method of the LED Display screen is to set the centimeter 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! Short-circuit detection should be performed when the circuit is powered off to avoid damage to the centimeter.
4. Display Screen Voltage Drop Detection Method
The LED Display voltage drop detection method is to adjust the centimeter to the diode voltage for the drop detection gear, because all the Cs 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 it in mind and carry out inspections at irregular times to avoid damage to our display screens, and can also extend the service life of our display screens. In this way, it can not only lengthen its use time, but also save the following unnecessary budget expenditures.
