Can't connect LG sound bar to SHARP TV
Hi, sorry for the long post, but I want to be as clear as possible. I want to connect my new LG sound bar (NB4540) to my 70" Sharp (LC70LE857U). Both are ARC and CEC enabled, so I tried to connect them using HDMI between them to get the sound of the TV directly on my bar.
I have activated everything that the manual says that I need to activate on the TV in order for this ARC connection to work. The bar does not require any setup since it indicates that it will switch to ARC input as soon as it detects it. However I can't make them work with this method. The sound still comes from the TV speakers (I used the Netflix app from the TV for testing purposes), and the Sound bar just stays there doing nothing. A curious thing is that when I turn off the TV using its remote control, the sound bar also turns off... but that is all that it does.
I tested an optical cable that comes with the bar, and it works, it sends the sound from the TV to the bar, but that doesn't solve the problem with the ARC connection, and as far as I know, this connection has lower sound quality than using HDMI, so I don't want to use it.
I have an LG 42" TV, which is 2 years older than the Sharp TV, also ARC and CEC enabled. I wanted to test the bar and the cables on this TV to see it the problem was there, so I connected the bar using the same method (HDMI cable between ARC ports, running Netflix app) and it worked! I went to the TV menu, activated the ARC feature, and the TV and the bar did the rest. The soundbar automatically changed to ARC input, and the TV remote now controlled the soundbar. It was a relief. Sort of...
Any ideas of how to setup the ARC connection with the SHARP?
