Circuit breaker stops the power.
Is the circuit breaker activated when you connect the power cord to wall socket?
How to fix
1. Check if there is an earth terminal in the wall socket.
If problem occurs only when you’re using a multi-tab, check the multi-tab.
※ If there is no earth terminals in multi-tab or many products are connected to it, circuit breaker may be activated.
2. If a cable is connected to the antenna terminals on the backside of TV, remove it and connect the power cord to wall socket.
When circuit breaker is not activated after you remove the antenna cable and connect the power cord to wall socket, this means the failure of antenna lines. You need to contact subscribed cable company or building maintenance office.
