Answers
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.
Ensure that 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 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, ensure that the device is on
and functioning correctly.
Press MENU on the TV's remote control. If the menu is
displayed, then the TV is working; recheck above steps.
Press INFO button on remote to confirm type of signal
being received.HD signal should be 720p, 1080i or 1080p.
Select a High Definition channel from HD source (Cable,
Satellite,Fiber optic or antenna).
HD channels sometimes broadcast non-HD content.
Ensure that HD source (HD box, Blu-ray player, etc.) is
connected to TV via either HDMI or Component cable and
set to output HD video signal.
If connection fails, contact your Internet service provider or
router/modem manufacturer to check for firewall, content
filter or proxy settings that may block TV from accessing
the Internet.
If your Home Theater has an HDMI-ARC Out, then connect
it to the TV's HDMI 2 (ARC) input using an HDMI cable.
If HDMI-ARC is not available, then connect the TV's
DIGITAL AUDIO OUT to the Home Theater using an optical
cable or connect to the headphone jack.
