第一：南桥的3VSB一定要有，最多的就是由1117分压得到，打值如果中间脚（一般为输出）对地的话，99%为南桥坏。集成的网卡也需要3VSB，短路的情况比较少见。
第二：32.768的晶振要起振，可通过波形来判断。或者用万用表测量其两脚的压差，这个方法基本准确。

67脚无电压不一定就是南桥坏了,有些是该脚3.3产生电路的场效应管出问题了
遇到过几例

我把图放上让大家看看 :victory:

放个JPG，省下大家的分数，希望大家喜欢

有很多板 73脚始终高电平。如何解释。

会员15

73脚一直为高电平，不跳变，说明南桥没有返回信号。
PS：一、原贴有些描述上的错误的地方，各位有心的朋友应能发现，不影响检修流程，所以不改了。
       二、黑色字表示IO脚位，红字表示跳变顺序。

哈哈1年后自己来回答自己提的问题了。
73脚一直高电平是因为强行断电导致南桥没有保存好休眠状态。。。。
