Billboards need to be maintained after a period of use. In order to avoid unnecessary problems, we need to check the billboard for a period of time. First of all, the brightness of the lamp column will naturally decrease when it is used for a long time. In order to ensure that the brightness of the lamp column is uniform, we need to check the lamp column regularly. If the light of the lamp column is very dark, we need to replace the lamp column. The following is about the maintenance of outdoor billboards, hoping to help you in front of the screen.
户外广告牌维护的七个流程：
There are seven processes for outdoor billboard maintenance
一、拆卸广告牌时，操作人员应佩戴纯棉和白色操作手套。如手汗油、盐、酸、碱等。成分有腐蚀性，请附着在不锈钢表面，会慢慢腐蚀褪色不锈钢表面的颜色，失去原有的美感。广告灯箱的定制拆卸灯箱的框架必须放置在光线，禁止碰撞和扭曲，框架应平放在地面上。
1、 When removing billboards, operators should wear pure cotton and white operating gloves. Such as hand sweat oil, salt, acid, alkali, etc. The composition is corrosive. Please attach it to the surface of stainless steel. It will slowly corrode and fade the color of stainless steel surface and lose its original beauty. The frame of the light box must be placed in the light. Collision and distortion are prohibited. The frame should be placed flat on the ground.
二、拔下插头，断开电源，然后检查原用电设备，检查要求中有详细描述，如电源线插入孔内，镇流器输入输出端子，灯座上的电线等。广告牌的尺寸必须与导光板的尺寸一致，不宜过大或过小，以免影响广告牌的显示效果和内热。
2、 Unplug the plug, disconnect the power supply, and then check the original electrical equipment, which is described in detail in the inspection requirements, such as the power line inserted into the hole, ballast input and output terminals, wires on the lamp holder, etc. The size of the billboard must be consistent with the size of the light guide plate, not too large or too small, so as not to affect the display effect and internal heat of the billboard.
三、安装广告牌时，将框架放平，放平后悬挂，然后关闭广告牌，用六角螺钉固定。
3、 When installing the billboard, level the frame, hang it after leveling, then close the billboard and fix it with hexagon screw.
四、检查广告牌顶部的电源线是否在电源插座插槽中，如果不需要校正。
4、 Check whether the power cord on the top of the billboard is in the power socket slot, if it does not need to be corrected.
五、关闭电源开关，检查指示灯是否正常。如果一边开着，另一边没开，请先断开电源，拔下插头，再检查灯头线是否松动;镇流器输入输出线是否松动等。
5、 Turn off the power switch and check whether the indicator light is normal. If one side is on and the other side is not, please disconnect the power first, pull out the plug, and then check whether the lamp cap wire is loose; whether the ballast input and output wires are loose, etc.
六、如果整个户外广告牌没有点亮，请检查漏电保护器是否闭合，插头内的导线接头是否松动，抑制器的输入输出接头是否松动等。
6、 If the whole outdoor billboard does not light up, please check whether the leakage protector is closed, whether the wire connector in the plug is loose, whether the input and output connector of the suppressor is loose, etc.
七、如果漏电保护器未能关闭电源，请检查电源线入口、镇流器和灯下馈线回路是否漏电。
7、 If the leakage protector fails to turn off the power supply, please check the power line entrance, ballast and under lamp feeder circuit for leakage.
