New Technical Features
2 new technical features have been added to the 2011 models to assist the service technicians speed up the
repair process.
The ability of the power LED to match the number of blinks of the first and last SOS blinking codes
detected by the TV as listed on the “SELF Check” menu.
The delaying of the power LED blinking reaction by 10 seconds when the SC/SN board is isolated.

The power LED can be forced to duplicate the number of blinks of the first and last SOS conditions detected by the TV.
This can be done while the power LED is blinking after a shutdown condition has occurred.
Procedure:
To duplicate the number of blinks of the last SOS detected.
While the power LED is blinking, press the “VOL+” on the remote control once to make the power LED blink the same
number of times as the last blinking code detected by the TV.
To duplicated the number of blinks of the first SOS detected.
Press the “VOL-” once to make the power LED match the number of blinks of the first SOS blinking code detected.
This can help in determining if the symptom shown by the
TV when it first failed (Most likely during operation), has
changed to another blinking code when checked by the
service technician.
Press VOL+ to see the
last SOS detected

Service port (M3 mini Jack) Specifications
The Service port (M3 mini Jack) on the following TVs can use as the RS232C terminal which is a
standard computer SERIAL interface.
Note: This operation system should be used by the certified professional dealer.
PC Control of the TV
The TV can be controlled by a personal computer when connected through an RS232C/ M3 mini jack
conversion cable (not supplied).
The computer will require software which allows sending and receiving of control data through its
SERIAL port.
