I have encountered a problem with either my 818 or Samsung F9005 tv, where I can't use ARC to get TV sound through the onkyo. I worked for 3 - 4 months and all was stellar, but suddenly the onkyo and samsung won't do ARC. I can't get the samsung to recognise the onkyo while setting up "anynet+" HDMI-CEC/RHID.
Samsung have replaced the one connect box for the tv twice, and it didn't change - I have run through the setup with a authorised dealer, who says the onkyo is set up fine, but it won't change to HDMI and is left on ANALOG when i select TV/CD.
I have changed between 5 HDMI cables, so its not the cables. I recon the HDMI board is at fault, but is there any other options?
