酷鱼芯片通用型号&nbsp
23400094可以代替23400269&nbsp
电机叮当&nbsp规则循环&nbsp盘体坏&nbsp
ST-U6（43434）自检后&nbspgala&nbspgala&nbspgala&nbsp盘体是好的&nbsp
100143434可以替代100124439反之则不行&nbsp
ST-U6&nbsp电机振动轻&nbsp有gada&nbspgada声音100143434坏了&nbsp
A、20V电压上不来BIOS有问题&nbsp
B、有异响换磁头驱动芯片&nbsp
C、坏道多&nbsp一般有线路板没关系&nbsp
D、不转&nbsp横向八爪或驱动芯片坏&nbsp
E、不自检&nbsp驱动芯片或场效应管坏&nbsp
F、上机响、屏蔽后不响电感坏正常10欧&nbsp
ST-U5和U6板型想象经验区别,U5在驱动芯片附近有三个电阻&nbsp
U6有4个电阻.&nbsp
ST跳线错,可能引起当当响.&nbsp
ST主芯片短路&nbsp烧驱动芯片或八爪&nbsp
摘下八爪不烧.摘下晶振烧八爪
