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" --> "Advanced audio". (p.32)
Check that the correct SAP (Secondary Audio Program) is selected
by pressing the SAP button on the remote control. (p.15)
If the TV is connected to a Panasonic Home Theater via HDMI
cable, then check VIERA Link controls. (p.22)
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", "HDMI 2 in" or "HDMI 3 in" analog/digital
audio settings. (p. 32)
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.
The Video input is shared with the Component input. Just
connect the yellow plug into the green jack. Be sure to
connect the red and white audio plugs into the appropriate
red and white audio inputs. (p. 10)
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.
During "First time setup", step 3, you indicated that the
"Antenna/Cable in" connector is "not used" (p.13). This is the
proper setting if the TV is connected to a Cable or Satellite
box via any of the other inputs. To re-activate the "ANT/
Cable" input, press MENU, select SETUP and then redo the
First time setup, selecting Cable or Antenna in step 3.
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.
