液晶显示器驱动板采用双面贴片安装技术,电路元器件布局紧凑,且型号标注不明确甚至未标注,再加上大部分液晶显示器根本找不到图纸,给查找具体元器件或走线都造成了很大的困难。有很多故障即使查找到损坏的元器件或芯片,由于市场上很难买到这些配件,也还是无法修复。因此,当驱动板出现故障时,除一些简单故障采用“芯片级”方法维修外,大多采用更换驱动板的方法进行维修,即“板级”维修。“板级”维修主要有以下两种方法:一是用液晶显示器“原装驱动板”进行更换。
LCD driver board with double-sided chip mounting technology, circuit components layout is compact, and the model label is not clear or even not marked, together with most of the LCD simply can not find the drawings, to find the specific components or traces are caused A lot of difficulties. There are many problems Even if you find damaged components or chips, due to the market is difficult to buy these accessories, it still can not be repaired. Therefore, when the driver board fails, except for some simple faults, the “chip level” method is used for maintenance. Mostly, the method of replacing the driver board is used for maintenance, that is, “board level” maintenance. “Board level ” Mainly in the following two ways to repair: First, the LCD monitor “original drive board ” to be replaced.
