Your Symphony soundbar is capable of HDMI Passthrough. HDMI Passthrough send video and audio signals from a HDMI source such as a Blu-ray player, HD Set Top Box or game console to the soundbar via a HDMI cable. The soundbar plays the audio from the HD source through its own speakers and sends the unaltered video signal to a TV via a second HDMI cable.
Follow the illustrations below to setup HDMI Passthrough on your Symphony soundbar:
Note
Once the setup is done, press the 
button repeatedly on the soundbar or the 
"SOURCE" button on the soundbar remote control to navigate to either HDMI IN 1 or HDMI IN 2.
On the TV, using the TV remote control change the Source/Input to the HDMI input that the soundbar is connected to.
Do note that only 1 HDMI input is usable at a time.
