I'd check that the XG tone generator works, that the silent piano generator works (should be if he's been using it for silent piano) and that the various inputs and outputs on the control box under the right hand side of the piano are working ok (volume, external audio volume, pedals etc). Also check that the control unit volume control works properly - mine is almost non-functioning now and it's been used in almost exactly the same way as your student (for silent practice). Also check the two pedals playback and record/playback OK. When you adjust the volume of the DKC500RW control unit the 'soft' pedal should move up and down as it moves the hammers closer to the strings. When you slide the middle practice pedal over to the left it should engage the mute rail and go into silent mode.
