Recently I have had a problem with my Sony MZ-NHF800 remote where, The Volume control on the remote is changing Tracks. The Display button sends it into Record mode . Titling tracks , produces other characters than you entered. Pressing the Radio button at any time does not turn the radio on and makes things worse. So thinking it was the remote I contacted the Sony North America's Depot Repair center where they want $161.95 for the remote RM-MC39LT. Almost half of what I originally paid for the entire MD unit. First I was told by customer service that the Flat fee for repair was $99.99 for entire MZ-NHF800 w/ remote for repair. Second time , $51 to send in remote , $99 to send in player. Like they wanted to charge each seperately. To me, it also seemed like Sony really wasnt interested doing anything for people that still own minidisc equipment. It may cost more to fix my MZ-NHF800, than to buy something else. Either its the Remote or some CPU inside the unit that is causing the malfunctions and their different each time No problem was the same, just random. You can notice that support and other options for MD are being discontinued or disappearing completely. Probably wont fix it.
