关于液晶电视的开机打印信息

dahldmzi

现在的电视越来越有点像电脑了。维修电脑可以用主板检测卡来了解主板的运行情况。维修电视是不是可以用开机打印信息来了解开机自检的情况呢？
我用升级中九的小板制作了一个转换头，就是把rx接到VGA插头的4脚，dx接到vga插头的11脚，（经过测试：用RT809F也可以，我用的是笔记本电脑，端口号：4）用自己编写的串口调试软件成功读取了创维26L08HR的开机打印信息，
附上我编写的串口调试软件。和读取的创维26L08HR的打印信息
软件直接安装后运行，设置好端口号（默认端口1），选中ASCII码。连接好中九升级小板，给电视机打开电源开关。打印信息就出现在编辑框内了。如果需要保存的话把他粘贴到记事本就行了。

我今天维修TCL C26E320B 主板。版号：40-ms8100-mae2xg,屏：LTA260AP06，主芯片MST6M181VS-LF-Z1.雷击故障。换好主芯片后不开机。读取的打印信息如下
：

经检查是125脚没有焊好，所以不开机，红灯也不亮。下面是补焊好以后的打印信息：
