Open the iron DC-DC power supply box, replace the blue ELNA capacitor, also clean the PCB.

谢谢您的解答,发帖后看了您解答另一帖子的回复,更换了6.3v330uf的电容,可惜电位器已损坏,更换后DC-DC输入为6V+,但输出却达到了惊人的18V+,准备购买可以代替的转换模块。请问下原厂模块是6-9V自动降压为4.5V么?我只会简单的维修,但对播放器有着执着的拯救兴趣,再次谢谢您对我和对大家的帮助。

The DC-DC module is used to charge battery base. You can replace the potentiometer and adjust it so that the output of the Vout should be 6.8V to charge your battery. Otherwise this part doesn't affect your DPC7.

DC-DC模块用于为电池基座充电。您可以更换电位器并对其进行调整,以便...

谢谢您的指导,犹如大海的灯塔,让我找到了方向,感觉离成功更接近了。现在通电正常,激光头归位上下发出激光,可惜显示disc,激光头部分有一阵明显的电流声,读碟动作完成后持续十几秒后消失,麻烦顾老师能否再次指点一下方向,谢谢您!

顾老师,现在机器有概率地读出曲目并播放,但是音乐伴随着噗噗声,请问是耳放部分的供电造成的问题么?
