Cautions regarding use in high and low temperature environments
• When the unit is used in a low temperature space (e.g. room, office), the picture may leave trails or appear
slightly delayed. This is not a malfunction, and the unit will recover when the temperature returns to
normal.
•
Do not leave the unit in a hot or cold location. Also, do not leave the unit in a location exposed to direct
sunlight or near a heater, as this may cause the cabinet to deform and the LCD panel to malfunction.
Storage temperature: f 20°C to e 60°C.
Possible Solution
• When the POWER switch does not work, remove the power plug and
insert it again, and then press POWER on the TV after waiting for more
than five seconds.
•
Is the AC cord disconnected?
•
Has the power been turned on? (See page 8.)
•
External influences such as lightning, static electricity, etc., may cause
improper operation. In this case, operate the unit after first turning the
power off the TV or unplugging the AC cord and re-plugging it in after 1 or
2 minutes.
•
Are batteries inserted with polarity (+, –) aligned? (See page 6.)
•
Are batteries worn out? (Replace with new batteries.)
•
Are you using it under strong or fluorescent lighting?
•
Is a fluorescent light shining on the remote control sensor?
•
Are screen mode adjustments such as picture size made correctly? (See
page 11.)
• Adjust the picture tone. (See page 9.)
• Is the room too bright? The picture may look dark in a room that is too
bright.
•
The unit's internal temperature has increased. Remove any objects blocking
the vent or clean.
•
Is the sleep timer set? (See page 11.)
• Is the connection to external equipment correct? (See page 4.)
•
Is the input source selection correct? (See page 8.)
•
Is the antenna connected properly? (See page 3.)
•
Is the volume too low? (See page 6.)
• This is not a malfunction. This happens when the cabinet slightly expands
and contracts according to changes in temperature. This does not affect
the TV's performance.
