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.


• 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: +5°C to +35°C.
