Answers
Make sure the volume is up and MUTE is off.
Confirm the TV speakers are set to ON by pressing MENU and
selecting "Audio" --> "TV speakers".
Check that the correct SAP (Secondary Audio Program) is
selected by pressing the SAP button on the remote control.
(p. 14)
If the TV is connected to a Home Theater via optical cable,
then: Check the connection, the audio system is on, the
correct input is selected.
Check "HDMI 1 in" or "HDMI 2 in" analog/digital audio settings.
Check that the correct SAP (Secondary Audio Program) is
selected by pressing the SAP button on the remote control.
Check that all connections of external equipment connected to
the TV are secure.
When using Cable or Satellite box, check the device's audio
settings. (Example: try changing the box's Audio Range to
'narrow')
When TV power is turned on or shut off, there are electrical
components that make a click sound. This is normal operation.
Changes in the temperature and humidity of the room may
cause thermal expansion and contraction that can produce
sounds. This is not a sign of faulty operation or a malfunction.
Use an HDMI cable. It carries both digital video and audio
signal in HD. HDMI cable is the only cable needed to connect
an HD device to the TV.
When viewing TV via an HDMI connected device, such as a
Cable or Satellite box, CC must be enabled at the device.
Closed Caption is available only at supported TV
programming.
The main unit radiates heat and some of the parts may
become hot. This is normal operation and does not affect the
performance of the set.
Ensure good ventilation.
Do not block the ventilation holes of the TV and do not place
the TV on top of other equipment.
Check that the batteries are fresh, are of the same type and
are installed with the correct polarity (+ & -).
To operate other devices, such as changing channels when
using Cable, or Satellite boxes, or operating non-Panasonic
Blu-ray players, use the remote supplied with the device.
Depending on certain modes or the selected input, some
options are not available. For example, Zoom adjustments are
only available when the FORMAT is changed to zoom mode.
In the main menu, select "Setup". Highlight "Reset to defaults"
and press OK. Enter your password (if created earlier) or
create a temporary new password. Select Yes to reset the TV.
