请问kaosun大师,有台松下ls-s303刚开始故障为最小音量声音也很大震耳朵的那种,随着电位器旋转也能增大音量,但幅度不大了,而且是单声道,由于没有维修手册也没搞定,后来一次试机的时候按住了play按键大概3秒钟,工作电流上升到1.2A左右,然后就有点焦味,不能开机了,再按PLAY电流100MA,松开play电流归零,求大师帮忙分析一下,或者有维修手册发我一份就更好了 同样如果有sl-s300 sl-s500或者松下T系列的xp300的维修手册也可以,我邮箱是569655555@qq.com  十分感谢补充一下 不通电之前line输出接口也是同样故障

不通电问题解决了,查到了给CPU供电的三极管损坏 然后更换了电源IC AN8083s和耳放芯片3414  现在故障依然是电位器最小音量是很大声音单声道,调到最大音量时有立体声了,但不太明显,line输出现在正常了。
另外一台机器通电后光头水平内圈到外圈前后乱动,偶尔也会上下聚焦,然后会降到最下面靠外圈的位置不动停一会,最后归位。请问是伺服问题还是线圈驱动芯片问题呢!光头确定是好的,光头内外移动正常
谢谢老师解答一下
还有个问题,这烧三极管的机器只要按住play2.3秒就会电流迅速增大到1安多,然后就烧CPU供电三极管。这如何解
