Bought a Marantz AV 1607 receiver in the US and was using at home in Bangalore during the last three months. Over a week ago on trying to play net radio it prompted, I suppose, an update messge for the firmware ; updating did not complete over several hours. Switching on after switching off, update error messages started appearing. Tool free call center technician tried guiding online but in vain. Atlast he suggested that I take it to their service center for fixing it. Is there someway it can be fixed here??
