Have you pressed MUTE on the remote control unit? Page 13

Check the audio output of the connected external equipment. Is the volume too low or muted?

When external equipment is connected via an HDMI cable, you may need to confi gure the audio to be output through the HDMI cable.

When audio is not output from external equipment connected to the INPUT 4 or INPUT 6 terminal, check the "PC Audio Select" setting. Page 24

Even when external equipment is connected using an HDMI-certifi ed cable, an audio cable connection may be required depending on the type of equipment and the media being played back. In this case, in addition to connecting an HDMI-certifi ed cable to the INPUT 6 (HDMI) terminal, connect an audio cable to the AUDIO terminal and set "PC Audio Select" to "Input 6 (HDMI)". Page 24

When connecting a PC via an HDMI-certifi ed cable, check the following:

-Is the audio output of the PC confi gured correctly? Check the audio output settings and output audio format in Sound Properties on the PC.

Only PCM format audio can be output. Compressed audio (with a sampling rate of 32kHz, 44.1kHz, or 48kHz) and DTS format audio cannot be output.

-Depending on the board, only video signals may be output. In this case, in addition to connecting an HDMI-certifi ed cable to the INPUT 6 (HDMI) terminal, connect an audio cable to the AUDIO terminal and set "PC Audio Select" to "Input 6 (HDMI)".

If you are using an HDMI-DVI conversion cable to connect external equipment to the TV, check the following:

-Is an audio cable connected? The HDMI-DVI conversion cable is for video only. Connect a Ø 3.5 mm stereo mini jack cable to listen to the audio.

-Is INPUT 6 being used? When the TV is connected to another HDMI terminal, the audio and video are not output together even if a Ø 3.5 mm stereo mini jack cable is connected to the shared AUDIO terminal for INPUT 4 and INPUT 6.

-Is "Input 4 (PC)" selected in "PC Audio Select"? Page 24
