If you have trouble, such as the picture not displaying on the screen or the remote control not working, reset the television with the following procedure:

If an external USB device is connected to the TV, disconnect the USB device from the TV before resetting.

Power Reset

Restart the TV with the remote control.
  1. Press and hold the power button on the remote control for about 5 seconds until the [Power off] message is displayed. Confirm this by pressing OK button and the TV will turn off.
  2. Unplug the AC power cord (mains lead).

If the problem persists after step 1, unplug the TV power cord (mains lead) from the electrical outlet and wait for 2 minutes.
Then plug the power cord (mains lead) back into the electrical outlet.
Note: Your personal settings and data will not be lost after the TV restarts.

Factory Data Reset

If the problem persists after a power reset, try a factory data reset.
  1. Press the [HOME] button, then select Settings > Device Preferences > Reset > Erase everything.
After the factory reset process completes successfully, your television will proceed into the FTI mode. You must agree to the Terms of Service and Privacy Policy.

Note: Performing a factory reset will delete all of the TV's data and settings (such as Wi-Fi and wired (ethernet) network setting information, account info, login information and installed apps)
