首先要確定是否一定是CD機的問題,再一步一步查下去。
那是什麼CD機呢?

Found the similar post in R33, so assume is same person la,

As mention in R33, the headphone output is OK, therefore:

1. DAC is OK
2. I/V conversion stage is OK, if needed. (op-amp base tpically)
3. LPF stage should be OK. (op-amp base typically)
4. Headphone amp OK (op-amp base)
5. Line buffer stage (Check this la)

唔該哂各位,原來OP附近粒電容鬆,補銲完有番聲,另想問新光頭條扁線唔小心整斷,唔知可否用番舊光頭條扁線(成條)銲去新光頭到?
有了這論壇對於像我這樣的新手真的很有幫助和鼓勵,遇到問題時有人幫助可以邊問邊試邊學習,希望已後多點有關DIY課程,因為我覺得香港的DIYER和國內或台灣的比較真的很少,

kik111,

that ribon cable (signal to laser head)can be buy at a lot shop, just bring your ribon cable to the shop to match.

Unless u r talking a bout the other flat cable to the motor of laser, then not easy to get in shop and can just solder it back.
