grf Posted September 27, 2006 Report Share Posted September 27, 2006 Hi,I have a friend who I converted to minidisc and he bought a MZ-NH800.He used it everyday for 2 years and it has now developed a fault which is unusual.When a disk is inserted, the track and contents are read as normal by the unit.However when it plays the sound is extremly distorted and sound like it is put through a 'flanger' type distortion.He has cleaned the laser lens, tried different disks, changed the output from headphones to an amp and still the distorted sound continues.Could the firmware be corrupted ?Any suggestions would be welcome.Graham Quote Link to comment Share on other sites More sharing options...
jonny mac Posted September 28, 2006 Report Share Posted September 28, 2006 I've never heard of a problem like that with MD, my NHF800 has never given me any problems. Have you tried a disc recorded on another unit? Perhaps the discs are corrupted. Quote Link to comment Share on other sites More sharing options...
bobt Posted September 28, 2006 Report Share Posted September 28, 2006 Have you tried it with different headphones as well.Good luck,Bob Quote Link to comment Share on other sites More sharing options...
philpem Posted September 29, 2006 Report Share Posted September 29, 2006 If this is one of the models with the 'virtual surround' or sound profiles, push the SOUND button on the remote until the far-right display is off (it'll be showing SND then a letter/number if it's enabled).IME virtual surround is pointless at best.

grf Posted October 23, 2006 Author Report Share Posted October 23, 2006 Hi Everyone,Thanks for all the replies to this topic. I have de-bugged the problem to a faulty earth on the headphone connector on the MD player. When I grounded it on one of the screws then all the distortion when away and the vocalist came back !Without an earth the signals that are equal on the left and right channels tend to cancel out as do similar signals. Putting the earth back with my soldering iron worked a treat.Best regardsgraham Quote Link to comment Share on other sites More sharing options...
