I was lucky enough to score a sanyo c4 but it seems that it only works on the radio function. when i play a tape or ipod through line in you can see the led meters jumping but you can't hear anything at all. i have tried the obvious things like flicking the function switches rapidly and etc but nothing. does anyone have any further ideas on what it might be exactly?
thanks!

thanks!
Tape input worked though so I plugged my external device in there...
