Maintenance
First, unplug the power cord plug from the wall 
outlet.
Power cord plug
Wipe the plug with a dry cloth at regular intervals. 
(Moisture and dust can lead to fire or electrical shock.)
Display panel
The front of the display panel has been specially treated. 
Wipe the panel surface gently, using only a cleaning 
cloth or a soft, lint-free cloth.  
●
If the sur face is par ticularly dir ty, soak a soft, lint-free 
cl

oth in diluted, mild liquid dish soap (1 par t mild liquid
dish soap diluted by 100 times the amount of water) 
and then wring the cloth to remove excess liquid. Use 
this cloth to wipe the sur face of the display panel, 
then wipe it evenly with a dry cloth of the same type 
until the sur face is dry. 
 
●
Do not scratch or hit the sur face of the panel with 
fi

ngernails or other hard objects. Fur thermore, avoid 
contact with volatile substances such as insect 
sprays, solvents, and thinner; other wise, the quality 
of the sur face may be adversely affected.
Cabinet
If the cabinet becomes dirty, wipe it with a soft, dry cloth.
 
●
If the cabinet is par ticularly dir ty, soak the cloth in 
di

luted, mild liquid dish soap and then wring the cloth 
dry. Use this cloth to wipe the cabinet and then wipe it
dry with a dry cloth.
 
●
Do not allow any mild liquid dish soap to come into 
di

rect contact with the sur face of the T V. If water 
droplets get inside the unit, operating problems may 
result.
 
●
Avoid contact with volatile substances such as insect
sp

rays, solvents, and thinner; other wise, the quality 
of the cabinet sur face may be adversely affected or 
the coating may peel off.
 
●
Do not let ar ticles made from rubber or PVC be in
co

ntact with the T V for long periods of time.
Pedestal
 
●
Wipe the sur faces with a soft, dry cloth. If the unit is 
pa
r ticularly dir ty, clean it using a cloth soaked with 
water to which a small amount of mild liquid dish soap
has been added and then wipe with a dry cloth.
Do not use products such as solvents, thinner, or 
household wax for cleaning, as they can damage the 
surface coating. (If using a chemically-treated cloth, 
follow the instructions supplied with the cloth.) 
 
●
Do not attach sticky tape or labels, as they can make
th

e sur face of the pedestal dir ty. Do not allow long-
term contact with rubber, vinyl products, or the like. 
(Doing so will cause deterioration.)
Troubleshooting
Before requesting service or assistance, please follow 
these simple guides to resolve the problem.
If an error message appears, follow the message’s 
instructions.
If the problem still persists, please contact your local 
Panasonic dealer for assistance.
Picture
Why is there no picture or just a blue, black or 
snowy screen being displayed?
 
Check if the power cord is plugged in and the TV 
is turned on (front red LED light should be on; not 
blinking).
 
Press the INPUT button on the remote control to 
select the correct input source.
 
Ensure all connections are correct and secure. 
When using external video source, such as a Cable/
Satellite box or DVD player, check that the device is 
on and functioning correctly.
 
Press MENU on the remote control. If the menu is 
displayed, then the TV is working; recheck above 
steps.
Why doesn’t the picture look like it is in High-
Definition?
 
Press INFO on the remote control to confirm the 
type of signal being received. HD signal should be 
720p, 1080i or 1080p.
 
Select a High-Definition channel from your HD 
source (Cable, Satellite or fiber optic service). HD 
channels sometimes broadcast non-HD content.
 
Ensure that your HD source (HD box, Blu-ray 
player, etc.) is connected to the TV with an HDMI or 
COMPONENT cable and set to output an HD video 
signal.
Why do black bars appear on the top and bottom 
and/or sides of the screen?
 
Change the format (aspect ratio) of the picture by 
pressing  FORMAT on the remote control (p. 15).
 
Check the aspect settings on your external video 
source, such as Cable/Satellite box, DVD/Blu-ray 
Disc player, etc.
Note: Some content, such as film-based movies, are 
available in extra-wide format. Top and bottom bars 
are unavoidable.
Why is the picture snowy when [ANTENNA/Cable 
In] is selected?
 
When using a cable service (without a box), check 
that all connections are secure. 
 
When using a cable or satellite box, change the 
connection to COMPOSITE, COMPONENT or HDMI 
(p. 11-12).
 
If you’re using an antenna, then check that 
connections are secure. Change the position or 
direction of the antenna and check the [Signal 
meter] (p. 14).

HDMI 
Why is the picture chaotic and/or torn and/or with 
a buzz in the speakers?
 
Check if electrical products such as kitchen 
appliances, fluorescent lights or light dimmers are 
nearby. They may interfere with the TV’s picture.
 
Try viewing a picture from another device, such as a 
DVD player or a game console, to narrow down the 
source of the problem.
Why is there a black box on the screen?
 
Change settings of Closed Caption (CC) 
(p. 15, 27).
Why is the screen blank and the power indicator 
blinking?
 
The TV has gone into shutdown mode to protect 
itself. Try unplugging it for a few minutes and 
connecting it again. If there was a temporary power 
surge on the AC line it may now be OK. If the 
blinking returns, visit www.panasonic.com/support 
(U.S.A.) or www.panasonic.ca/english/support 
(Canada).
Why do some small spots on the screen remain 
bright or dark?
 
The TV panel is made up of a few million pixels 
and is produced with advanced technology through 
an intricate process. Sometimes a few pixels may 
be bright or dark. These pixels do not indicate a 
defective panel and will have no impact on the 
performance of the TV.
Sound
Why is there no sound coming from the TV? 
Make sure the volume is up and MUTE is off. 
Check that the correct SAP (Secondary Audio 
Program) is selected by pressing  SAP on the 
remote control (p. 15).
 
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 [HDMI1-2 in] analog/digital audio settings 
(p. 20).
Why is the sound unusual, distorted, low volume 
or in another language?
 
Check that the correct SAP (Secondary Audio 
Program) is selected by pressing  SAP on the 
remote control (p. 15).
 
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. 
 
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.
Other
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 do parts of the TV become hot?
 
The main unit radiates heat and some of the parts 
may become hot. Even if the temperature of parts 
of the front, top and rear panels has risen, these 
temperature rises do not cause any problems in 
terms of performance or quality.
 
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 (+ 
and −).
 
To operate other devices, such as changing 
channels when using Cable or Satellite boxes or 
operating non-Panasonic Blu-ray players, use the 
remote control of the devices.
