Ensure the TV is plugged into a mains socket and, if necessary, try an alternative mains socket. An extension lead does not always supply the TV with sufficient power, so the TV may not be able to turn on fully if connected this way.

We would recommend trying the below steps:

1. Unplug the TV from the wall and disconnect any external devices.
2. Hold down the manual button on the unit for 30 seconds (if unsure of location please refer to the user manual).
3. Plug the TV back into a mains socket.

If this has not resolved the issue, please contact us using the details on this page.

If the TV is disconnecting from the internet, we would recommend trying the following:

• If multiple variations of your router appear in the network selection screen, select the one which does not have 5GHz at the end.
• Check that the TV is not situated too close or too far from the router, and that there are no obstructions that may be physically blocking the signal.
• Reset the WiFi router.
• Check if other devices are experiencing the same issue, or if it happens at a particular time. This may suggest there is an event triggering this loss of connection.

Check that all connections are fully inserted on both your TV and viewing source (for example, an aerial or a Sky box). If the issue persists, please try the following.

1. Unplug the TV from the wall and disconnect any external devices.
2. Hold down the manual button on the unit for 30 seconds (if unsure of location please refer to the user manual).
3. Plug the TV back into a mains socket.
