My 3year and 4month old 609 had the HDMI fault with the audio cutting out. This had been going on for a while but I thought it was my TV signal,Hdmi leads,player etc. Took a while to figure out. Sent it away to Avalon and received the Onkyo back after 15 days - no charge - new HDMI PCB and all fixed. Big ups to Onkyo and Avalon to sort this known issue with the extended extended warranty!
