SONY D33 CD机没声音

顾老师：sony d33之前都一直好好的，后来电位器有声音，拆下来清洗，后换上去，彻底没声音了，又从另一台D33换了一个好的电位器依然没声音，可能后边电路板下边垫了电线不小心短路了？现在光盘读盘正常，但是彻底没声音，能解决吗？谢谢

Check and let me know whether you have output from LINE OUT?

line out也没有声音，用手触摸电位器或者触摸电路板上一个六会有噪音。D:\

Pls check the DRAM wiring of the DSP CXD1135, anyone the wiring breaks will lose sound. Next, check power supply of DAC chip and audio pre-amp. You can refer SM of the D33 from our download section.
