MHZS CD66 噪音?

我買咗呢架機,我果架喺relay開咗(的一聲之後)仲未有音樂果幾秒/又或者音樂好細聲時,就有wee wee聲,音量喺10点左右,好想死呀,我己經將解碼D水塘換過,都一樣係咁,度8V同5V輸出去解碼,play CD時,5V好定,冇上落,但8V就跌0.3V, 有冇人有線路圖?又或者有冇人有解決辦法? :cry: Thankyou,
Ray

2nd hand item with modi b4??

摩前是否正常.



看看CD頭弓機械部份.可能CD頭碰到東西,

我用緊部CD 33﹐ 一D NOISE都無﹐係咪摩完至咁 ?

架機一返黎,最先聽時覺得聲幾好,不過薄咗D,換咗CV4004就好D,然後換只金Carol Kidd,一play首when I dream,死火,點解有wee wee聲,換CD/換胆(用返跟機胆),情况依然,之後攞去比人睇,查到以上問題,佢諗可能係水塘有事所以換咗嗰八枝大水塘,又試過換Opamp,點知 ops: ,最後就係冇線路圖冇得攪,唔知有冇人可以幫手?
另外點解想死?你地D機最多經五六十公里就到你屋企,有問題攞去換到得,我果架飛咗六千幾七千公里先到我果度China>Sydney,你叫我點換呀 :?: 真係失望到想死 :cry:

If the CD66 is still with you, u can try this way! open cover, play & see how the cd move/turn, see it move smooth or not.

Then try to adjust the white button at the back of the laser head, it can be turn clockwise/anticlock wise. See whther the sound still wee.wee..

i have the simolar problem recently after i had some of the cap in my BADA HD21, the voltage supply to the laser head will drop a lot during playing.... (before play cd ~3.5v, when play-->0.08v, sometime motor just can't move)(BADA's circuit & CD mechanism quite similar to CD33/66)

After tuning the white button at the back of the laser head, it is ok.... u need to try & error to see whether shall turn clockwise/anticlockwise, normally i will pres stop then tune the button then play to see the way the cd move, see it smooth or not & listen to the sound.

Thank you,已試過,不過一樣怪叫,不過比多咗兩千買DAC-MD10 ops: D銀兩愈來愈少 ops:

一早買部MD-10 DAC, 就唔洗煩噪音問題.....

如果每个人都好象dynamic兄那么有$$$，要买就可买，就天下太平咯 :  :  :

WINDWSS兄,
雖然我岩岩買左MD-10 DAC,
我意思話ozrayyau兄,
如果維修+摩改CD66都用一千幾百, 不如買過部更好
更好的有...可能CD88...可能加DAC

DynamicdogÐÖ，

开国玩笑而已请别介意 ops:

一般上如果机出了问题， 对DIY有兴趣的人都会尽力找办法修好它！随然所花的钱和时间可能更多但学到东西的机会也相应增加。。。
