Useful Information
TROUBLESHOOTING
HITACHI LCD Rear Projection Television incorporates advanced power surge protection technology designed to
protect against component or circuit damage due to external or internal voltage power surges.
IF YOUR TELEVISION SHOULD APPEAR TO HAVE A LOSS OF POWER, PLEASE FOLLOW THIS
PROCEDURE:
1. Press the POWER
SWITCH (ON/OFF
SWITCH) once.
2. If there is still no power,
wait 30 seconds and
press the POWER
SWITCH again.
3. If there is still no power,
unplug the power cord
from the wall. Wait 30
seconds and plug the
power cord back in.
Press the POWER
SWITCH again.
This protective technology
should provide for years of
lasting entertainment from
your HITACHI LCD Rear
Projection Television.
DO
Dust the screen and cabinet with a soft cloth.
Clean the screen with a soft cloth moistened in warm
water and dry with a soft cloth. A mild soap may be
used if the screen is extremely dirty.
Place your Television away from extreme heat,
humidity, and extremely dusty places.
Remove the plug from the wall outlet if your Television
will not be used for a long period of time, for instances,
when you go on vacation.
DO NOT
Do not clean your screen or cabinet with strong
cleaners, polishes or a chemically treated cloth.
Do not place rubber or vinyl products or cellophane
tape on your Television.
Do not touch the screen too often.
Do not subject the remote control to shocks such as
dropping it on the floor, etc. Physical damage to the
precision parts may result.
Avoid placing the remote control in a high humidity
place or getting it wet. Do not leave it on or near a
heater. Excessive heat or moisture may cause the unit
to cease operation.
When the batteries run down, remote control operation
will become erratic or possibly stop altogether. Replace
the old batteries with two new “AA” size batteries as
soon as possible to preserve the remote control
precodes that were set for the devices. Pressing a
remote control button with a “DEAD” battery might
erase all precodes in memory. Do not use an old
battery with a new battery.
Exposure of the viewing screen to prolonged direct
sunlight or heat may cause the screen to permanently
warp, resulting in a distorted picture..
