How to get to Burn-in mode

This mode displays the test patterns of some single color raster in turn. These signals are from built-in gener-
ator of panel. So it can be presumed that maybe the panel has some trouble when the screen of Burn-in
mode is abnormal.
Using the remote control with the set turned on can activate the mode.
(1) Set the service adjustment mode.
(2) Change No.646 from “0” to “1”. After a few second, appear the burn-in picture.
(3) To escape from this mode, change No.646 from “1” to “0”.

At first, please confirm whether you put a connector cable again, and a phenomenon comes out.

[no picture, no sound]

LED is not light.

Is the voltage of

pin 5 (+5.4V) of CNPS

(power supply unit)

normal?

It is trouble of Main PWB

or Power supply unit.

Please change.

No

It is trouble of Main PWB or

Terminal PWB.

Picture trouble Go to “A”

Sound trouble Go to “B”

Yes
