Troubleshooting

The problems described below are not always caused by malfunctions. Check the TV again before having the TV

serviced.

Problem

• No power.

• Unit cannot be operated.

• Remote control unit does not

operate.

• Picture is cut off.

• Strange colour, light colour, or

dark, or colour misalignment.

• Power is suddenly turned off.

• No picture.

• No sound.

• The TV sometimes makes a

cracking sound.

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.

Storage temperature: f 20°C to e 60°C.

• 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 ﬁ ve seconds.

• Is the AC cord disconnected?

• Has the power been turned on? (See page 6.)

• 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.

• Are batteries inserted with polarity (+, –) aligned? (See page 5.)

• 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?

• Are screen mode adjustments such as picture size made correctly? (See page 10.)

• Adjust the picture tone. (See page 8.)

• Is the room too bright? The picture may look dark in a room that is too bright.

• Check the colour system setting. (See page 10.)

• The unit's internal temperature has increased.

Remove any objects blocking the vent or clean.

• Check the Setup setting. (See page 10.)

• Is the sleep timer set? (See page 5.)

• Is the connection to external equipment correct? (See page 4.)

• Is the Picture Mode adjustment correct? (See page 7.)

• Is the antenna connected properly? (See page 3.)

• Is the volume too low? (See page 5.)

• 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.
