Option Bytes
To enter Factory Mode:
Software Upgrade:
Software Upgrade can be performed by network connection or downloading the latest firmware
from “www.samsung.com” to a USB memory device.
- By USB
Insert a USB drive containing the firmware upgrade file. DO NOT disconnect the power or
remove the USB drive until upgrades are complete. The TV will be turned off and on
automatically after completing the firmware upgrade. When software is upgraded, video and
audio settings you have made will return to their default settings.
NOTE: The displayed menu may differ depending on the model.
- By Online
Upgrades the software using the Internet.
First, configure your network. If The internet connection doesn’t operate properly, connection
can be broken, please retry downloading. If the problem still happens, download by USB and
upgrade.
- Standby mode upgrade(Off/On)
A manual upgrade will be automatically performed at selected time. Since the power of the unit
is turned on internally, the screen may be turned on slightly for the LED product. This
phenomenon may continue for more than 1 hour until the software upgrade is complete.
Testing Bluetooth Operation (3D glasses and Smart Remote):
Bluetooth communication will automatically activate when the TV is turned on. To test,
use a cell phone with Bluetooth capabilities, and “SCAN for devices”. If Bluetooth
communication is working properly, “DTVBluetooth”will appear on the phone. If not,
suspect Main PCB, or Bluetooth module is defective.
