Hi,
I need help with my Sony mini hifi model: FH-411R. There's no sound when I plug in a source to the CD line in (RCA) left channel. CD line in right channel and both channels through AUX in work fine.
Does anyone know what could be wrong? Do u have a schematic for my use? Pls email:
[email protected]
or reply to this Thread. Thanks! |

Still haven't got the svc manual...
I have since done some manual circuit tracing. Prime suspect: 4-ch Multiplexer IC part no. MC14052B. Will try to replace to see if it works... wish me luck! |

Quick update guys...
I've replaced IC302 (MC14052) - 4-ch multiplex and it worked! This IC functions as the input selector (ie. Tuner, AUX, Tape, CD) to pre-amp.
1 item less for the landfill! |
