POWER on the TV.
2. Is the AC cord disconnected?
3. Has the power been turned on?
Unit cannot be operated 1. External influences such as lightning, static electricity, may cause improper operation. In this case, operate
the unit after first turning off the power of the TV or unplugging the AC cord and re-plugging it after 1 or 2
minutes.
Remote control unit does not operate 1. Is the SOURCE set correctly? Set it to the TV setting position.
2. Are batteries inserted with polarity (+, -) aligned?
3. Are batteries wron out?
4. Are you using it under strong or fluorescent lighting?
5. Is a fluorescent light illuminated near the remote control sensor?
Picture is cut off /with sidebar screen 1. Are screen mode adjustments such as picture size made correctly?
Strange color, light color, or color misalignment 1. Adjust the picture tone.
2. Is the room too bright? The picture may look dark in a room that is too bright.
3. Check the input signal setting.
Power is suddenly turned off 1. Is the sleep timer set?
2. The unit’s internal temperature has increased. Remove any objects blocking vent.
No picture 1. Is connection to other components correct?
2. Is correct input signal source selected after connection?
3. Is the correct input selected?
4. Is picture adjustment correct?
No sound 1. Is the volume too low?
2. Have you pressed MUTE on the remote control unit?
The TV sometimes makes a cracking sound 1. This is not malfuntion. This happens when the cabinet slightly expands and contracts according to change in
temperature. This does not affect the TV’s performance.
1. When a lamp in LCD panel is broken and the
protector circuit in inverter operates and we
tune on the this set, LED keep red? or Green?
2. Service man only change the lamp in LCD
panel?
1. If the lamp(s) is(are) broken, panel inverter will not kick on the lamps, so TV set phenomena will be "no picture
on display."
But the TV system is still working, that is the RC can also control LED.
When AC power on, the LED will keep last status and when use RC DC power on, the LED will keep green light.
2. The failed panel should be sent back to Panel maker (CMO) via RMA process.
Panel maker (CMO) will not rework the lamps at customer's side since the repaired panel should be checked
through regular inspection flow to secure the quality.
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: -4°F to +140°F (-20°C to +60°C).
