My TX-SR707 receiver was purchased in November 2009 and gave problem (no sound) on September 01. I took the Onkyo authorized and was informed that it should be changed 1B234532-1A Onkyo Hdmi Pc Board but they would have to ask this part ..
As was already without warranty researched information from others with the same problem as mine and to my surprise there were few.
This board is very expensive and honestly think the ONKYO should make a RECALL of it,
Apart from that it not only cuts the sound of the equipment connected to the HDMI, also all analog connections.
Anyway became a receiver unusable which paid $ 800 at HHGregg

What do ONKYO??
I live in Rio de Janeiro, Brazil.
I have the bill of sale
