Notes:
• Certain cable systems offset some channels to reduce interference or have Premium (scrambled) channels. A cable
converter box is required for proper reception. Check with your local cable company for its compatibility requirements.
• To obtain optimum quality picture and sound, an antenna, the correct cable (75 Ohm coaxial) and the correct terminating
plug are required.
• If a communal antenna system is used, you may require the correct connection cable and plug between the wall antenna
socket and your television receiver.
• Your local television service centre or dealer may be able to assist you in obtaining the correct antenna system for your
particular area and the accessories required.
• Any matters regarding antenna installation, upgrading of existing systems or accessories required, and the costs incurred,
are your responsibility.

This TV is capable of displaying 1080i and 480p DTV signals when connected to a DTV Tuner Set-Top-Box (STB). This
TV also utilizes a progressive scan doubler, which de-interlaces the NTSC signal and progressively scans the image.
This allows you to sit close to the TV and not see the thin black horizontal lines (venetian blind effect) associated with
interlaced TV pictures.
• To view DTV programs, connect the STB to the component video input terminals (Y, P
B, PR) of the TV. Component color
inputs provide luminance and separate color signal.
• Select the output of the STB to either 1080i or 480p.
• A DTV signal must be available in your area.
• Use a Panasonic DTV-STB (Digital TV-Set-Top Box) or DVD Player.

HDMI Connection
HDMI∗1 (High Definition Multi media Interface) is the first all digital consumer electronics A/V interface that supports
uncompressed standard. The HDMI terminal supports both video and audio information.
To the HDMI∗
1 input terminal, you can connect an EIA/CEA-861/861B∗2 compliant consumer electronic device, such as
a Set Top Box or DVD player with HDMI or DVI output terminal.
Input a High-bandwidth Digital Content Protection (HDCP) high-definition picture source to this HDMI terminal, so you
can display the high-definition pictures on this TV in the digital form.
∗1. HDMI, the HDMI logo and High-Definition Multimedia Interface are trademarks or registered trademarks of HDMI
Licensing LLC.
∗2. EIA/CEA-861/861B profiles compliance covers profiles for transmission of uncompressed digital video including
high bandwidth digital content protection.
∗3. HDMI-DVI conversion cable (TY-SCHO3DH): available on Panasonic Website (www.panasonic.com). Consult your
consumer electronics dealer for availability details.• If the external device has DVI output only, use a
DVI to HDMI adapter cable*
3 to connect to the HDMI
terminal.
• Connect the audio cables to the AUDIO IN terminals
for HDMI.
• Select the audio setting in HDMI In (see page 29).
This input terminal is not intended for use with computers.
Notes:
• This HDMI connector is Type A.
• If you connect an equipment without a digital output terminal, connect to the COMPONENT VIDEO, S VIDEO or
VIDEO input terminal on the TV so you can enjoy an analog signal.
• The DIGITAL IN terminal can only be used with 1080i, 480i or 480p picture signals. Set the Digital Set -Top -Box
DIGITAL OUT terminal Output setting to 1080i, 480i or 480p. For detailed information, refer to the Digital Set -Top -
Box instruction manual. If you cannot display the picture because your Digital Set -Top -Box does not have a
DIGITAL OUT terminal Output setting, use the component Video Input (or the S Video Input or Video Input). In this
case the picture will be displayed as an analog signal.HDMI cable
