二、维修故障：黑屏、无法启动，面板无显示，开机不显示等故障维修。

三、西门子PCU50工控机维修成功案例如下：

　　一、故障现象：

　　开机不显示。

　　二、故障原因

　　经过与客户的沟通，我们了解到此西门子PCU50工控机因为不小心进水原因造成无法开机故障。

　　三、处理办法

　　我们根据以往维修此故障的经验，首先把工控机主板拆下来，用眼睛查看整个板子有无烧坏的器件以及经水浸泡后有无腐蚀的器件，发现没有，就对电源进行检测，各路电压均都显示正常，可就是加电测试不显示问题，测量地址线与数据线也没有发现短路，测量I/O同样没有发现什么问题，就是加电测试不自检，又开始对时钟检查，发现时钟信号不正常，测试各路时序，有的有有的没有，把时钟芯片与晶震换上，上电测试各时钟信号正常了，这时机器也发出报警声了，内存没有安装，关机把内存安装好，开机一会儿，久违的画面出来了，出现BIOS自检，在到没有发现硬盘，整机安装好，连到系统上
