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.
