Hey @TonyLewis ,
this is not expected from our TVs. Other devices could be interfering with your TV. If you have connected other devices the TV may be receiving a signal from the other device and then turns on. Can you please unplug the HDMI cable from your TV and all the devices and cables going to your TV for a few hours and let me know if this has solved the issue?
If this doesn't help, I think that is worthy to get this examined by one of our engineers. Please contact the Support Team to get this arranged: https://www.samsung.com/uk/support/contact/
