Hi there and welcome

There can be a few causes for this.

Can you remove the power to the TV (so unplug it from the power socket) then on the TV itself hold the power button for 60 seconds, then release.

Wait 10 minutes, connect the power and turn on the TV and tell me how it now operates.

Let me know the results please.
