[quote:9ea7e2a83a="ozrayyau"]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,

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. |
