I am trying to hook up a Panasonic Blu Ray SA-BT235 to a Vizio E700i-B3 tv. I get picture but no sound. I have a new HDMI cable as well as the 3 coaxial cable. I also have a optical cable as well?
Connect the HDMI-ARC output on the Panasonic to the HDMI-ARC input on the TV. No other cables needed.
Turn ARC on in the TV menu. You may also need to turn the TV speakers off. Check the owners manuals.
Stick with HDMI connection only. On the TV, "optical" is most probably output-only.
Try changing audio (sound) modes on your BD/DVD player. You should choose something like "Stereo only".
