No HDMI output
So I have a 55" LG LED TV. Its a couple years old ( don't know the model # ) BUT it doesn't have any input/outputs on the TV itself. There is one (1) HDMI input on the TV itself. All the other inputs are on an accompanying receiver that send everything to the TV wirelessly. Heres the problem ; Id like to install a sound bar BUT how do I get an audio signal to it? Obviously I understand I could run either an optical or HDMI to the sound bar from the receiver, but Id rather not. The TV is installed nicely on the wall with no cables, and the wireless receiver is adjacent to it in a small cabinet with the Bluray, cable box, etc etc. Does LG make a compatible sound bar that works with their wireless TV's? Short of running a wire ( tons, and I mean TONS of work at this point) is there any other option?
