How to upgrade the software
1
Pull out the AC cord to turn off the TV.
2
Insert the SD card for version upgrade (prepared as above) into the service socket located below left of the
right side cooling fan in the rear of the unit, in a way that the cut corner of the SD card comes at the right-
hand side.
Note: If the SD card is inserted in a wrong way, the card will go deep inside the unit beyond retrieval. Take due
care to insert the SD card correctly.
3
Hold down the "SYSTEM RESET" button at the lower left of the rear of the unit, and plug in the AC cord to
turn on the TV.
Note: The "SYSTEM RESET" button can be released after the TV turns on.
(4) Several to ten-odd seconds after the unit starts, the following version upgrade screen appears.
5
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.
6
Upon completion of the whole process, the upgrade success screen as shown below appears. You can
check the new software version on this screen. The version information appears after the upgrade is
complete.
