change in room temperature may cause moisture condensation,
resulting in a blurry picture or poor color. Turn off your TV and
wait a few hours before powering on again.
• Check the volume control.
• Press MUTING or VOL + so that "Muting" disappears from the
screen (see pages 22 and 23).
• Set Speakers to TV Speakers in the Sound settings (see page
38). 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
38).
• 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
38).
• Set Audio Out to Fixed in the Sound settings (see page 38).
• Verify that the Video/Component Selection (see page 48) is set
to the current input type in use. We suggest leaving this setting to
Auto.
• Make sure that the BRAVIA Sync Control is set up on both the
TV and the optional device compatible with BRAVIA Sync (see
page 26).
• Only one A/V receiver may be used with the BRAVIA Sync and
BRAVIA Sync Control functions at one time (see page 49).
