Explanation/Solution
• Check the volume control.
• Press MUTING or VOL + so that "Muting" disappears from the
screen (see page 26).
• Set Speakers to TV Speakers in the Sound settings (see page
53). If it is set to Audio System, sound is not output from the TV's
speakers regardless of the TV's volume control.
• When using HDMI input with Super Audio CD or DVD-Audio,
DIGITAL AUDIO OUT (OPTICAL) may not provide an audio
signal.
• When tuned to a digital channel with Alternate Audio, the
broadcaster may not be broadcasting your preferred Alternate
Audio language. Press OPTIONS, highlight and select Alternate
Audio, and change the Alternate Audio language (see page
53).
• Make sure that the antenna is connected using a 75-ohm coaxial
cable (not supplied).
• Keep the antenna cable away from other connecting cords.
• To avoid TV interference, make sure to use an undamaged
antenna cable.
• Set Speakers to Audio System in the Sound settings (see page
53).
• Set Audio Out to Fixed in the Sound settings (see page 53).
• Verify that the Video1/Component Selection (see page 63) is
set to the current input type in use. We suggest leaving this
setting to Auto.
• Make sure that the Control for HDMI is set up on both the TV
and the optional device compatible with BRAVIA Sync (see
page 30).
• Only one A/V receiver may be used with the BRAVIA Sync and
Control for HDMI functions at one time (see page 64).
• Confirm the PC is correctly connected to the TV with either the
PC IN (with an HD15 cable) or with the HDMI IN.
• Ensure the output signal from the PC is one of the formats listed
on page 67.
• Turn the PC off. Confirm the PC connection and restart the PC.
Plug-and-play will auto-detect the TV and correctly set up PC
timing.
• Verify the PC is not in standby or hibernation mode.
• Adjust the resolution (see page 67).
• Adjust Pitch and Phase (see page 55).
