LED显示屏按照行业区分还是属于电子产品,只要是电子产品,那么在使用过程中就难免会出现故障。那么有哪些维修LED显示屏的小技巧呢? 接触过LED显示屏的朋友们都知道,LED显示屏是由一块一块的LED模组拼接而成。前面说到LED显示屏是电子产品,那么它的基本结构就是显示面(灯面)、PCB(电路板)、控制面(IC元器件面)。 说到维修LED显示屏的小技巧,首先说一下常见故障。常见故障有:局部“死灯”、“毛毛虫”、局部色块缺失、局部黑屏、大面积黑屏、局部乱码等等。 那么如何维修这些常见的小故障呢?首先要准备维修工具。LED显示屏维修工的常备五件宝:镊子、热风枪、烙铁、万用表、测试卡。其他的辅材有:锡膏(锡线)、促焊剂、铜丝线、胶水等。 一、局部“死灯”问题 局部“死灯”是指LED显示屏的灯面上有一颗或者几颗灯不亮,这种不亮区分为全时不亮和部分颜色不亮,一般这种情况是灯本身出现了问题,要么是受潮,要么是RGB芯片损坏,我们维修的方法很简单,就是用工厂配的LED灯珠备品换上即可,那么使用的工具就是镊子、热风枪,换上备品LED灯珠以后,用测试卡重新测试一遍,没有问题就是已经修好了。 二、“毛毛虫”问题 “毛毛虫”只是一个比喻的说法,系指LED显示屏在通电条件下而没有输入源的时候,部分灯面出现一长条的暗亮条的现象,且以红色居多。出现这种现象的根本原因是灯内部芯片漏电,或者背后的IC面行管线路短路,前者为大多数。一般出现这种情况,我们只需要拿着热风枪沿着漏电的这一条变色“毛毛虫”吹热风,当吹到有问题的那颗灯,一般就OK了,因为受热使得内部漏电的芯片连接澎开了,但是仍然存在隐患,我们只需要找到漏电的那颗LED灯珠,按照上面讲到的方法,把这颗隐患灯珠换掉就OK。如果是背后IC面的行管线路短路,就需要使用万用表具体测量一下相关的IC针脚电路,换一颗新的IC即可。
