Hello everyone. I have a recording noise / hiss problem on my MDS JB980: as soon as I press the rec button from the line / headphone outputs there is a strong white noise / hiss and, low in the background, the input audio. The problem is present on any input (analog, optical, coaxial) and also in the passband (ie simply pressing the rec button, with no disc in the drawer, as is always done to adjust the recording levels). Unfortunately, since I don't have other minidisc machines or pre-recorded discs, I don't know if the problem is present even in read-only mode. If, in rec, I lower the recording volume to zero the noise disappears completely. Last detail: with any audio input the volumes on the vu-meter appear regularly; in the absence of an input signal, the vu meters show nothing (but in both cases the output noise is heard). From these observations I think that the origin of the problem is electronic and not of the pick-up but I don't know how to solve it. Please, can anyone help me? Thank you all.
