Supplement: The customer care support from Onkyo has approved a written request to repair in March 2014 and assumed the cost of replacing the HDMI board on goodwill (the service of Onkyo dealer "Hifi service Kruse" is here to mention greatly to be praised! ). For 2 weeks thus the amplifier is working properly again and therefore I raise again the vote on 4 stars because the device again loosely met all expectations. I hope, however, that not again in 2 years the same defect occurs .... To all who have similar problems: do not give up, the guys from the Customer Care do their job when one is pretty clear ... Because of the excitement: 1 star deduction, but still good 4 star for the device.
