LED广告屏简单问题处理方法

【时间】2018-09-14【来源】网络

LED广告屏在中国发展了二十多年,已全覆盖进入人们的视野当中,走在路上到处可见形状各异的LED广告屏,它所显示的内容可以是文字信息,也可以以图像或视频的形势展现。LED广告屏不像电视只是单纯的显示产品,而是集光学、电子应用、力学、美观等综合于一体,LED广告屏在应用过程中,难免会出现一些故障,或者排线松动,或者软件操作有误,下面小编总结了LED广告屏日常使用中经常出现的情况以便于及时排除。
我们先来分析下LED广告屏的构成,它主要由LED模组、LED控制卡、LED电源、短排线、长排线、5V电源线、220V过箱电源线、强电缆及380V强电、配电箱、视频处理器、功放音响、散热、结构等部分组成。
(1)LED广告屏出现有规则的大块黑色不亮
可以检查软件分区是否有覆盖情况,其次检查网线、电源线是否松动,再次检查电源是否供电,如果供电正常,可以检查接收卡扫描是否正常,相信通过这一系列的排除方案,LED广告屏问题可以有效排除。
(2)LED广告屏一排过去不停的闪烁,类似乱码的情形
这个问题可以判定为单排LED模组信号供给不正常,排除方法是可直接将接收卡出来的长排线直接跳到有问题的LED模组,如果正常显示,则证明此块LED模组是正常的,接着将排线插到此块模组的右侧检测上一块模组是否正常。
如果也正常,那就更换两块LED模组间短排线即可,如果发现有块模组不正常,则可以判定此块LED模组驱动芯片有故障,寄回LED广告屏厂家维修或者现场更换就可以了。
基本上LED广告屏遇到的问题就这么多,或者一整块,或者局部,按照上述的方案检测就可以了。如果您遇到其它LED广告屏故障,可向您购买的LED屏的公司进行反馈。
