A: Make sure to connect the cables to the correct outputs on your external AV source and the inputs on your television. Press the INPUT or SOURCE button to select the input mode that corresponds to your connection to the external AV source. Ensure your external AV source is on. Check for the correct settings in the Audio Select menu on your TV.
If this doesn’t work, reset all your connections. Power cables or HDMI cables can come slightly loose overtime and lose connection. Start by unplugging the power cable from both the TV and the wall outlet. Next, unplug the HDMI cable from the TV and your media player. Ensure that both are firmly plugged back in; this will reset the connections. You may also try fully unplugging the power from you media player and re-plugging it back in.
