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.
