> Insert the USB Memory for version upgrade (prepared as above) into the service socket located Right side from center at terminals, above HDMI4 terminal in the rear of the unit.
>> Plug in the AC cord with power button pressing after 5 seconds later, release the power button. [SERVICE MODE]
> After the unit start-up, the system upgrade screen as shown below appears within 20-40 seconds.
Even a single failure in the process will trigger the upgrade
failure screen as shown below. the word "NG" changes to red for the
item failed.
NOTE: In the event of a failure, repeat the upgrading process. If the process repeatedly fails. it is likely that the hardware is troubled.

MONITOR MICROPROCESSOR SOFTWARE UPGRADE
Create the USB memory for monitor microprocessor software
version upgrade in the same manner as explained in the "Main software
version upgrade". Copy the file
42LTMxxx.USB and 42LTMxxx.BIN(named temporarily ) for monitor microprocessor
software version upgrade to the USB memory.
How to upgrade the software
