Outdoor LED Display Modules for routine maintenance
 Now outdoor LED Display Modules can be said to be very common in the streets of the city can be said to be everywhere. Many people found that the outdoor LED Display Modules is composed of the mold, not a whole block. In this regard, because the outdoor LED Display Modules every day outside the sun and the sun, so the maintenance work must be done, or else it seems how bad to see how awkward. Here we talk to everyone and chat with the outdoor LED Display Modules how to maintain Well.
    1, multi-block module is not bright or abnormal: check the signal direction of the first block of abnormal module cable and the power cord is in good contact, such as the module without LED light, then no power input, please check the power section , If there is color that the module no signal input, please check the first block of the module is not the normal input of the cable is tight, can be repeatedly plug the test, such as the problem can still exchange the new cable.
    2, single-module does not light: check the module's power supply is good, mainly check the module on the power outlet is loose. Such as the block module appears color confusion or color inconsistency for the signal transmission row county contact bad, re-plug the cable, or replace the test cable. Such as the replacement of a good cable still have the same problem, please check the PCB board interface is a problem.
    3, a single light does not light Detection method: Check the LED with a multimeter is damaged, if the light is broken by the following 5 items for the lights. Specific lamp method: the multimeter hit the resistance X1 file, pointer multimeter black pen then LED positive, red pen then negative, if the LED light, the measured lamp is good, if the light does not light, the measured lamp is bad.
    4, LED bad point maintenance (out of control):
    Front maintenance: with the corresponding model of the screwdriver from the front will be fixed to remove the face mask screws, remove the mask, change the lamp, change the lamp and colloid seal after the end of the original mask to restore, tighten the screw, and finally if the colloid remain on the LED surface Please carefully remove the colloid.
    Back Maintenance: Remove the cable from the back with the corresponding model screwdriver, unplug the signal cable, and do not unplug the power cable to prevent accidents. Carefully remove the module from the sheet metal hole and move it to the box On the back, and then in accordance with the front maintenance method for a single module to maintain the change lamp (please follow the lamp changing method for the lamp) or maintenance of the other.
    5, for the lamp: the damaged colloid around the LED with a sharp tool to remove, and make the LED pin clearly exposed in the line of sight, right hand with tweezers pinch the LED, left hand with soldering iron solder, and do a little stay (no more than 3 seconds Clock, such as over time but does not meet the demolition requirements, please cool and then try again) will melt the solder, with tweezers to remove the LED. Will meet the requirements of the LED lights into the hole of the PCB circuit board, and will melt a little solder wire, bonding on the tip of the tip, with tweezers to adjust the direction of the LED to make it smooth, the solder will be welded to the LED and PCB connected, Use the same type of colloid (PH = 7) to seal the LED.
    Above is the outdoor LED Display Modules in the use of which we need to do the maintenance work, if you do not pay attention to the work of this time when the content, then the maintenance work is to do is not in place.
