If your TV has no power at all, here are some methods to do the troubleshooting for your reference:
1. Check if you plug the power cord into the socket properly or not.
2. Unplug the power cord and plug it back into the socket. Then please check whether the standby indicator is on.
3. Change another socket to plug the power cord, so we could know if the socket causes the problem or not.
If the issue cannot be resolved, please feel free to call TCL hotline for further help.
