Both the TV and receiver seem to have BT receivers not transmitters.
You may have to turn the audio output on, the TV speakers off, and change the audio output type in the TV menu to get it working, The receiver connection you used for the TV to has to be assigned to an input (such as CD or aux). If you get the TV audio output turned on then you can use a BT transmitter but you don't need two. Just one on the TV paired to the receiver. You will only get a stereo input from the TV that way so no digital surround sound. Use an optical cable if you can.
