Limitations on use of photo, video, and music files
The TV supports MSC(Mass Strong Class) USB devices only. MSC is a class designation for mass storage devices. Types of MSC devices include external hard drives, flash card readers, and digital cameras. (USB hubs are not supported.) These kinds of devices must be connected directly to the USB port. The TV may not be able to recognise a USB device or read the files on the device if it is connected with a USB extension cable. Do not disconnect USB devices while they are transferring files.
When connecting an external hard drive, use the USB(HDD) port. We recommend that you use an external hard drive with its own power adapter.
Certain digital cameras and audio devices may not be compatible with the TV.
The TV supports the FAT and NTFS file systems.
After sorting files in the Folder view mode, the TV can display up to 1,000 files per folder. If the USB device contains more than 8,000 files and folders, however, some files and folders might not be accessible.
Certain files, depending on how they are encoded, may not play on the TV.
Certain files are not supported on all models.
DivX and DTS codecs are not supported by the Panasonic.

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.
Screen
Red, blue, green or black spots on the screen.
This is the characteristic of liquid crystal panels. The liquid crystal panel is built with very high precision technology. Occasionally, a few non-active pixels may appear on the screen as points of red, green, blue or black. This does not affect the performance of your TV and it is not a quality problem.
Chaotic image, noisy.
Set [Noise reduction] in the [Picture] menu to remove noise (p. 13).
Check nearby electrical products (car, motorcycle, fluorescent lamp).
No image is displayed.
Check the settings of [Contrast] or [Brightness] in the [Picture] menu (p. 13).
Check the TV is in AV mode. If the TV is in AV mode, check the selected input mode match the output of the external equipment (p. 10).
Unusual image is displayed.
Turn the TV off with Mains power On / Off switch (p. 10), then turn it on again.
Pictures from equipment connected via HDMI are unusual.
Check the HDMI cable is connected properly.
Turn the TV and equipment off, then turn them on again.
Check an input signal from the equipment (p. 18).
Use equipment compliant with EIA/CEA-861/861D.
Sound
No sound is produced.
Check the sound mute setting (p. 9) and volume.
Low level or distorted sound.
Sound signal reception may be deteriorated.
Sound output via HDMI connection is unusual.
Set the sound setting of the connected equipment to "2ch L.PCM".
General
The TV goes into Standby mode.
This TV is equipped with auto power standby function (p. 18).
The remote control does not work or is intermittent.
Replace the batteries (p. 5).
Point the remote control directly at the remote control signal receiver of the TV (within about 7 m and 30 degree angle).
Situate the TV away from sunshine or block sources of bright light from shining on the remote control signal receiver of the TV.
Parts of the TV 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.
The TV panel moves slightly when it is pushed with a finger.
Clattered sound might be heard.
There is some flexibility around the panel to prevent damage. This is not a malfunction.
Overcurrent error message appears.
The connected USB device might cause this error. Remove the device and turn the TV off with Mains power On / Off switch, then turn it on again.
Check foreign objects are not inside the USB port.
Maintenance
First, remove the mains plug from the socket outlet.
Regular care
Gently wipe the surface of the display panel, cabinet and pedestal by using a soft cloth.
Wipe the mains plug with a dry cloth at regular intervals. Moisture and dust may lead to fire or electrical shock.
For stubborn dirt
First clean the dust on the surface. Dampen a soft cloth with clean water or diluted neutral detergent (1 part detergent to 100 parts water). Wring the cloth and wipe the surface. Finally, wipe away all the moisture.
Caution
Do not use a hard cloth or rub the surface too hard as this could scratch the surface.
Do not subject the TV's surfaces to water or detergent. Liquid inside the TV could lead to product failure.
Do not subject the surfaces to insect repellent, solvent, thinner or other volatile substances. This may degrade surface quality or cause peeling of the paint.
The surface of the display panel is specially treated and may be easily damaged. Take care not to tap or scratch the surface with your fingernail or other hard objects.
Do not allow the cabinet and pedestal to make contact with a rubber or PVC substance for a long time. This may degrade surface quality.
