In fact, we all know that an indoor LED display product no matter how good the quality is, there are maintenance, its life span in addition to the quality of the product itself, maintenance is also an important key Indoor LED display, like any other products, it is reasonable to have problems. What we can do is to better find out about the problems before they come and do the maintenance work in advance as far as possible. So what are the maintenance and detection methods of indoor LED display screen? How should the user do a good job of indoor LED display screen detection?
1. Indoor LED Screen resistance test, resistance test method for indoor led display, we need to dispatch multimeter to resistance, first detection of another piece of normal circuit board to the ground resistance of some point, and then detect the same point test another piece of the same circuit board, if there are different with normal resistance and know if there are different then the scope of the problem of indoor led display, the opposite Will be.
2. indoor LED display voltage detection method: indoor LED display voltage detection is to adjust the multimeter to the voltage file, detect a suspicious and problematic circuit of a point to the ground voltage, compared with the previous is normal, so that it can be convenient to determine the problem.
3. indoor LED display short circuit detection method: indoor LED display short circuit detection method is to adjust the multimeter to short circuit detection block, so that you can detect whether there is a short circuit phenomenon. If there is a short circuit phenomenon, it should be solved immediately. The short circuit phenomenon of indoor LED display screen is also the most common indoor LED display module failure. In addition! Short circuit detection should be performed when the circuit is powered off to avoid damage to the multimeter.
4. indoor led display pressure drop test: indoor led display pressure drop test is to press the multimeter transferred to the diode drop tests, because indoor led display all the IC is composed of many unit parts, so when it’s on a pin is energized when will exist in guide | foot drop. Under normal conditions, the pressure drop on the IC pin of the same model is similar.
For the above several indoor L ED display maintenance methods we can keep it in mind, in the time of detection, to avoid the damage of our indoor LED display, can also be very good to extend the service life of our indoor LED display. In this way, it can not only prolong its use time, but also save unnecessary budget expenditure.
