1、是否有断线；
2、分力元件如电阻、电解电容、电感、二极管、三极管等时候存在断开现象；
3、电路板上的印制板连接线是否存在断裂、粘连等；
4、是否有人修过？动过哪些元器件？是否存在虚焊、漏焊、插反等操作方面的失误；
在确定了被修无上述状况后，首先用万用表测量电路板电源和地之间的阻值，通常电路板的阻值都在70-80？以上，若阻值太小，才几个或十几个欧姆，说明电路板上有元器件被击穿或部分击穿，就必须采取措施将被击穿的元器件找出来。具体办法是给被修板供电，用手去摸电路板上各器件的
温度，烫手的讲师重点怀疑对象。若阻值正常，用万用表测量板上的阻、二极管、三极管、场效应管、拨段开关等分力元件，其目的就是首先要确保测量过的元件是正常的，我们的理由是，能用万用表解决的问题，就不要把它复杂化。
方法二：先外后内
使用工具：电路在线维修仪
如果情况允许，**是找一块与被维修板一样的好板作为参照，然后使用一起的双棒VI曲线扫描功能对两块板进行好、坏对比测试，起始的对比点可以从端口开始，然后由表及里，尤其是对电容的对比测试，可以弥补万用表在线难以测出是否漏电的缺憾。
方法三：先易后难
使用工具：电路在线维修仪、电烙铁、记号笔
为提高测试效果，在对电路板进行在线功能测试前，应对被修板做一些技术处理，以尽量削弱各种干扰对测试进程带来的负面影响。具体措施是：
