鄰居的床頭音響故障，請我幫忙看看
就….勉為其難檢查囉
液晶顯示Error 162
CD無法退片…這台蠻特別的是五片式片系統
搞了一陣子無法在控制面板上排除，應該是機件問題哩
想想後決定搬回家研究看看，鄰居總要互相幫忙的嘛
於是…開始大卸八塊
拆拆樂活動開始....囧
邊拆邊研究機構....拆裝多次後大致了解CD進退片及讀取流程

| 這就是CD片槽，黑色的那五片 |
裝回拆掉好幾遍就是出現錯誤....
以下是網友的排除建議：
To my knowledge, error code '162' on most JVC units indicates a mechanical problem particularly with the CD mechanism.
Possible reasons the CD disc will not eject are:
- load/eject mechanism faulty which may be a loose or fault belt, worm gear, tray mechanism;
- lock mechanism will not release disc;
- an erring disc is locked in the play mechanism (most likely).
Initially, what could be tried:
- power off and unplug the JVC for an extended period of time;
- press and hold the eject button while plugging the unit back in; or
- tap/knock on the trays or loading/eject area while pressing on the eject button 3 times (eject, load, eject);
- using a pair of tweezers, carefully pullout all the trays to ensure that no disc(s) are inside;
- manually load but gently (push) all trays;
- turn the JVC upside down;
- tap on the bottom;
- the idea is to dislodged any erring disc left in the play mechanism but not in the tray.
- carefully open the unit (make sure it is unplugged);
- manually work the mechanism to eject the disc trays;
- inspect any obvious faults such as broken belt, missing gear teeth, warped/dislocated guide rails.
Hope that this be of initial help/idea. Good luck and thank you for using JustAnswer.

後來在放棄之際....竟打了瞌睡...醒來後突然想到連動機制的感應器
就是下面照片右方的IC版....
拆下後用電表量一下阻抗，哦~
SW1、2、3、4、5量測時1跟2電阻抗很高
嘿嘿....就是你們兩顆在搞鬼，不過開關動作正常
應該是內部金屬接點氧化導致接觸不良
於是想辦法弄到正常....阻抗小於0.002就OK了(原本阻抗0.9xx在跳)
如下圖電表顯示
真的就是那小塊IC搞鬼，修好後裝回就都正常了
經驗值增加500分~XD
