Why is there no sound coming
from the TV?
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. 34)
Check that the correct SAP (Secondary Audio Program) is
selected by pressing the SAP button on the remote control. (p. 16)
If the TV is connected to a Panasonic Home Theater via HDMI
cable, then check VIERA Link controls. (p. 29)
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. (p. 34)
Why is the sound unusual,
distorted, low volume or in
another language?
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’)
Why is there a clicking, ticking
or buzzing sound coming from
the TV unit?
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.
What is the easiest and best
way to connect a High-Definition
Cable or Satellite box to the TV?
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.
Why does the CC button not
display Closed Caption?
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.
Why does the screen and back
cover of the TV get warm?
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.
Why doesn’t the Remote
Control work?
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.
Why is the “ANT/Cable” option
at the top of the “Input select”
menu gray-out and cannot be
selected?
During “First time setup”, you indicated in step
-
that
you are using Cable or Satellite box and in step
-
b that
the box is connected to one of the TV’s AV inputs. In this
case, the Antenna/Cable input is deactivated to prevent
unintentional switching into unused tuner. To re-activate,
press MENU, select SETUP and repeat “First time setup”.
Some menu items are grayed-
out and cannot be selected.
Why?
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.
