Incomplete network upgrade may be caused by a power outage or network disconnection during the upgrade process.
1. Please turn off the power for 30 seconds, then reboot and check if the TV is working properly.
2. If the TV can be started normally, please try network upgrade again with good network. Do not power off during the upgrade process.
3. In case that this problem cannot be solved, please give feedback to the local TCL after-sales service point, and we will help you solve the problem.
