Screen goes black 2/3 times when first turned on

I have a TCL QM8 65 inch, every time I turn on the TV and the streaming box (Firestick or Sky Stream) the TV screen goes black then comes on again, it does this 2/3 times then all is good

Hi @maggieedwards

It might be trying to establish a connection for the signal.

What happens if you press the TV Menu button on the remote after the TV is turned on, do the TV menus appear and stay on?
