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.
