Try turning off the Anynet+ option in the menu. Anynet+ is CEC (consumer electronics control), and would power on the TV and switch the inputs. Turning off Anynet+ may solve the problem.
This thing changes my PHILLIPS TV to HDMI 2 and then the system reverts to Function of DVD/CD.
This happens with both the Tuner Funtion as well as the Aux 2 Funtion. I do have everything connected properly and this thing is not supposed to TURN my TV ON and change the channel to HDMI 2. Again, I have a Phillips TV and a Samsung HTS.
Customer Support (after 1 hour) suggested my only option is to unplud the HDMI cable from the back of the box every time I want to listen to tuner or play Nintendo.
Any thoughts or ideas out there to fix this?
