ANTENNA
Unless your LCD Rear PTV is connected to a cable TV system or to a centralized antenna system, a good outdoor
TV antenna is recommended for best performance. However, if you are located in an exceptionally good signal
area that is free from interference and multiple image ghosts, an indoor antenna may be sufficient.
LOCATION
Select an area where sunlight or bright indoor illumination will not fall directly on the picture screen. Also, be sure
that the location selected allows a free flow of air to and from the perforated back cover of the set. To avoid
cabinet warping, cabinet color changes, and increased chance of set failure, do not place the TV where
temperatures can become excessively hot, for example, in direct sunlight or near a heating appliance, etc. When
using your LCD Rear PTV against a wall, keep it at least 10cm (4 inches) from the wall.
NOTE: Your new HDTV has a built-in high definition television signal processor. This television includes a fan
to cool the processor. The sound of moving air from the fan is normal and may be noticeable in very
quiet environments.
VIEWING
The major benefit of the HITACHI LCD Rear PTV is its
large viewing screen. To see this large screen at its best,
test various locations in the room to find the optimum
spot for viewing.
The best picture is seen by sitting directly in front of the
TV and about 10 to 18 feet from the screen. Picture
brightness decreases as the viewer moves to the left
and right of the receiver.
During daylight hours, reflections from outside light may
appear on the screen. If so, drapes or screens can be
used to reduce the reflection or the TV can be located in
a different section of the room.
If the TV’s audio output will be connected to a Hi-Fi
system’s external speakers, the best audio performance
will be obtained by placing the speakers equidistant
from each side of the receiver cabinet and as close as
possible to the height of the picture screen center. For
best stereo separation, place the external speakers at
least four feet from the side of the TV, place the
surround speakers to the side or behind the viewing
area. Differences in room sizes and acoustical
environments will require some experimentation with
speaker placement for best performance.
IMPORTANT NOTES:
1. Since LCD Rear PTV incorporates a high pressure lamp to display an image, it may take about one
minute for the picture to become stable, after the power has been turned on. After extended use, the
picture may darken, the color may look unusual, or the lamp “goes out,” (burns out). You may hear a
“pop” sound when the lamp “goes out.” These are common characteristics of the lamp, and should
not be considered defective.
2. LCD Rear PTV incorporates an advanced cooling fan system to prevent from overheating. If you hear
the cooling fan, it should not be considered defective.
3. If you hear a “cracking” sound from the TV cabinet, it is due to the TV’s cabinet expanding and
contracting due to room temperature changes. It has no effect on the TV’s functions.
4. The LCD Rear PTV cabinet is constructed with
wood and plastic
. Make sure to place it on a flat surface.
An uneven surface might warp the cabinet and reduce the picture quality.
