Some of our TVs have a master power switch and come out of the factory with this switch set to 'OFF'.
This switch will be located either next to the power cable on the back of the TV, in the bottom right-hand corner of the TV, or under the right-hand side speaker.
Please ensure that you have this switch set to 'ON'. Please then try and turn your TV on.
The hard power switch will look similar to the below picture:
If this does not resolve your issue, can you please attempt the following:
1. Unplug it from the main power socket, leave it for 10-15 minutes before plugging it back in and turning it on.
2. Try connecting it to a different wall socket.
3. Ensure that nothing is blocking the infrared sensor and that you are pointing the remote directly at it. The infrared sensor is a usually a small black box that is protruding from the bottom edge of your TV.
4. Try different batteries in your remote.
