The Plasma 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.
Turn the C.A.T.S. feature off.
Press MENU -> Picture > C.A.T.S.
Make sure the volume is up and MUTE is off.

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 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.
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.
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.
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.
In the main menu, select "Setup". Highlight "Reset to defaults"
and press OK. Enter your password (if created earlier) or
create a temporary new password. Select Yes to reset the TV.
