hello everyone . ive got a denon ud-m30 that ive had for about 4 years recently its developed a fault when using the volume dial to decrease the volume . when the dial is turned anti clockwise to decrease the volume the volume increases by randon amounts i.e 18,21,19,23, and so on so it often ends up at full volume and its difficult to turn the volume down . the other problem ive been having is that the volume often takes it upon its self to increase on its own so one minute you can be listening to a cd or whatever at background volumes and the next it scares you s**tless by blaring out at full volume . if any one can shed any light on this or it is known to be a common fault id be very gratefull for some advice .
