A quick look seems to write both have Anynet+ and since this was implemented in HDMI 1.0 my guess is out of date firmware in either device, a bad HDMI cable, settings or an odd thing like this in the manual.
"If you have selected an Anynet+
device using the Source function
, you cannot use the Anynet+
From what I'm reading you want to connect the HT over HDMI port 2.
I have an UE46ES7000 tv and cannot connect to my surround system (HT TX-35) through Anynet+, they are connected with a hdmi and an optical cable together.
Anynet is enabled on the tv, but when I search for devices it says that no device connected.
Any help is appreciated.
