HOW TO SETUP YOUR NEW HITACHI LCD TELEVISION
VIEWING
The major benefit of the HITACHI LCD Television 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 5 to 11 feet from the
screen.
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.

Notes
A buzzing sound might be heard when the LCD television is turned on in a very quiet room. This is due to the LCD
display panel drive circuit when it is functioning. This arching sound is normal and it is not a malfunction.
Some infrared rays are emitted from the LCD television's panel that might affect other infrared controlling
equipment.
High-precision technology is used to manufacture the LCD display panel; But in some cases, there are minor
defects in some parts of the screen. Points that do not light, points with brightness different from that of the
periphery, points with color different from that of the periphery, etc. Some pixels will always be on or always off.
Please note that this is not a malfunction.
When receiving still picture signals, (e.g. channel number indication or clock indication) for a while, you can see
image-like when the picture varied. This is not a defect.
The LCD display panel is made from glass. Heavy shock on the front panel might damage it.
Do not press the panel surface hardly, this would cause "Mura" effect on the screen.
When the LCD television is transported horizontally, the glass panel has the possibility of being broken or
increasing the picture defects. At the time of transportation, horizontal style is prohibited. More-over, please treat
the LCD panel with great care because of a precision apparatus. Please instruct transporters so that it should be
put into the packing box at the time of shipment. (There is a possibility that breakage of the panel or defects will
increase.) Rough transportation might cause damage to the panel and pixel failure.
The LCD TV illuminates phosphor to display images. The phosphor has a finite illumination life. After extended
periods of illumination, the brightness of the phosphor will be degraded to such extent that stationary images
would burn-in that part of the screen as grayed-out images.
Tips to prevent such image retention are:
- Do not display images having sharp brightness differences or hi-contrast images, such as monochrome
characters and graphic patterns, for long.
- Do not leave stationary images appearing for long, but try to refresh them at appropriate intervals of time, or try to
move them using screen saver function.
- Turn down the contrast and brightness controls.
When a screen is seen at point-blank range, a random fine grain may be visible to a dark part.
be received.
There is some time lag between the picture and the sound. You can see lip motion that is
delayed compared to the sound.
Electric discharge/luminescence characteristic of the LCD display panel also changes with peripheral temperature.
Moreover, since there is also high power consumption value, a specified temperature environment is required.
Storing the LCD television for a period of more than 2 to 3 months without use might cause an unstable picture
when the set is turned on.
Operating altitude: 800 to 1,114hPa (6,194ft to -2,484ft). Operating temperature: 41°F to 95°F.
Storage Altitude: 300 to 1,114hPa (31,912ft to -2,484ft). Storage temperature: 5°F to 140°F.
Frequent use of the Power ON or OFF might trigger the power protection circuit. If the TV
does not turn ON, please wait a little before turning ON again.
