A purple background is an indication that the input signal is not connected correctly.

Check that all cables are securely connected at both ends - both at the rear of the TV, and any devices they are connected to.

Should you have any questions in the future, feel free to reply back at any time.

Have a good day and stay safe,

Pete.
