My entertainment set-up is: LG 55LS5700-TB Smart TV, Sony Receiver STR-DH750, a couple of re-chipped Tivos and a Dish TV T2200.
- The TV is connected to the Receiver from the TV HDMI-ARC port to the Receiver's HDMI-ARC port which is fantastic as the TV remote now controls the on and off of both the TV and Receiver as well as the volume.
- The Tivos are connected by HDMI directly to the TV's HDMI Inputs.
- The Dish TV T2200 is connected by HDMI directly into the one of the receiver's HDMI inputs.
I have had this set-up for at least a couple of years without any problems. Just recently I started having problems with the HDMI-ARC feature between the TV and the Receiver after I had turned off the power to all the units/devices when connecting a new modem. It now appears that the Dish TV is over-riding the HDMI-ARC between the TV and Receiver and the Dish TV is now acting as the Audio Return Channel or the go between with the TV and the Receiver, meaning if the Dish TV is in standby mode the HDMI-ARC feature will not work unless I turn on the Dish TV.
I have individually plugged the units in one at the time and tested the HDMI-ARC as I went. Everything would work perfectly till I turn off the DISH TV, it completely stops the TV HDMI-ARC port from functionally. Even though the TV settings say that ARC is on and the Receiver settings is also set correctly. I have to turn the Dish TV on for the ARC feature to work which I didn't have to before.
My research into this problem looks like it is to do with a CEC setting within the Dish TV T2200 itself. I cannot find a way to turn this CEC setting off in order to stop it from interfering with the function of the HDMI-ARC directly between TV and Receiver. I have found some models of Dish TV had the options to turn this feature on or off, but cannot find any options with the Dish TV T2200.
I am hoping somebody may have had the same problem as me and have been able to fixed this problem. I believe this problem may have started after a firmware update recently and had nothing to do with me powering off all my device/units when I connected a new modem to my set-up.
Thanks.
