If the TV stays on the start-up screen, please follow the below methods to do the troubleshooting:
1. If you connect a set-top box to the TV, please remove the set-top box to check whether the TV could start up successfully.
2. If the TV could start up successfully without the set-top box, we suppose that the set-top box is the root cause of the issue.
3. If the TV still cannot start up successfully, please try to unplug the power cord and plug it back in.
If the issue cannot be resolved, please feel free to call the TCL hotline for further help.
