Question about Sony MHC-RG660 CD Shelf System
It is possible that during your absence, there was a power outage/interruption, a thunderstorm or even a spike in the power lines.
Initially, have you tried a full hard reset? If not, pls unplug from the mains. Most current devices would reset and revert back to factory default settings (assuming no internal hardware fault) when unplugged for a considerable period of time (a couple of hours).
Other than the above, there is no other user action possible as the unit has to be opened requiring knowledge with electronic components and circuitry. If the full reset is still a no go, then perhaps your best bet would be to seek the services of a qualified professional.
Hope this be of initial help/idea. Good luck and kind regards.
Thank you for using FixYa.
