Hi, I owned the Sony MZ-R50 for 5 years or more... Recently, I try to use it to rec the music from CD device via optical cable... Unfortunally, I can only get the message " Line In " from the LCD screen. ( That's means the R50 did not receive any optical signal ). Before, I make sure it is working very well for optical cable. Now I have no idea why... Is anyone who has experience for it? Any suggestion are welcome for this case. Thanks~ Ray
