Troubleshooting
The problems described below are not always caused by malfunctions. Check the TV again before having the
TV serviced.
Problem Possible
Solution
• No power.
• Check if you pressed
POWER
on the remote control unit. (See page 8.)
If the indicator on the TV lights up red, press
POWER
.
• Is the AC cord disconnected?
• Has the power been turned on? (See page 8.)
• Unit cannot be operated.
• External infl uences such as lightning, static electricity, etc., may cause improper
operation. In this case, operate the unit after fi rst turning the power off the TV or
unplugging the AC cord and re-plugging it in after 1 or 2 minutes.
• Remote control unit does not
operate.
• Are batteries inserted with polarity (
e
,
f
) aligned? (See page 6.)
• Are batteries worn out? (Replace with new batteries.)
• Are you using it under strong or fl uorescent lighting?
• Is a fl uorescent light shining on the remote control sensor?
• Picture is cut off.
• Are screen mode adjustments such as picture size made correctly? (See page 12.)
• Strange colour, light colour, or
dark, or colour misalignment.
• Adjust the picture tone. (See page 10.)
• Is the room too bright? The picture may look dark in a room that is too bright.
• Check the colour system setting. (See page 9.)
• Power is suddenly turned off.
• The unit’s internal temperature has increased.
Remove any objects blocking the vent or clean.
• Is the sleep timer set? (See page 5.)
• No picture.
• Is the connection to external equipment correct? (See page 4.)
• Is the picture adjustment correct? (See page 10.)
• Is the antenna connected properly? (See page 3.)
• Is “On” selected in “Audio Only”? (See page 12.)
• No sound.
• Is the volume too low? (See page 5.)
• The TV sometimes makes a
cracking sound.
• 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.
Cautions regarding use in high and low temperature environments
• When the unit is used in a low temperature space (e.g. room, offi ce), 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.
