請問 那處可以Repair Musical Fedelity CD 機? 今天發覺電箱制跳線. 謝謝。

好大機會是整流子 short 哂，火牛太大电流引至跳fuse, 呢d 機有時仲易整

謝謝. 知否到那處可修理？

MF 乜型号

A3.2CD thks.

集中檢查火牛後那堆零件, 整流子, 電容, 穩壓管

有冇 他表, 度 d 整流二極管有冇 short 左, D 電容有 冇漏漿 short 底板, 穩壓管有冇 short 落地, 起碼做左呢 d, 先再算, 咁先對得住架機

Hi 254mm, thank you. let's PM

架 Musical Fidelity A3.2 CD pl;ayer 壞得好神奇, 網友話某日佢記得好清楚熄左架機去訓教, 奇在弟朝總制箱跳 fuse, 佢試到係架 A3.2 令到跳 fuse, 佢話駁 A3.2 條電源線駁去另一 d 機正常運作, the information avail;able is very useful, it indicates the power input in front of the switch is definitely out of order. After checking, a Y capacitor in the filter section is shorted, Thus replacing a new EMI filter will fix the problem, now it is playing CD flawlessly!!

平時我唔做呢 d 修理 other than replacing laser heads, 但呢架機壞得咁怪, 忍唔住接黎整, 卒之找到病因, just to ease my mind!!

呢架機个上蓋好難拆，d 位做到剛剛好，好實

254MM 兄,
非常感謝你的幫助!

#9 & #10﹐good fix!

尾插濾波電容short左，火牛唔接尾插試試。
