Repair of Denon Amp.

Recently my 12 yrs old mini HiFi (model: UDRA-F05) has such problem : the left channel has no sound occasionally. Every time I switch on the machine, I have to plug/unplug the interconnect cable (CD port) a few times in order to make it work.

Does any C Hing has face this problem before and could I fix it by myself... Thx!

清潔下D dust

拔下再裝返D插線

再不是換了個Relay 同 RCA 插頭,看下有沒改善、因為呢種時得時不得最難整

ic... Thx!

Actually, I have called Denon and told them the symptom of it. They seems having experience of fixing it. Does it worth to pay ~1K for a 12-yrs old machine

全部日本電容

Mini Hi-Fi 來說,用料不差

如果蚊蚊插插可以出到聲, 應該係個RCA頭O的線鬆左
重新焊過就OK, 氧化左就直頭換對新RCA頭
