Hi there and welcome
There can be a few causes for this Patricia.
First though, what is the make and model of your TV?
Can you please remove the power to the TV (so unplug it from the power socket).
Then on the actual TV, hold the power button for 60 seconds then release.
Then wait 10 minutes, connect the power again to the TV, turn it on and tell me please if it is now operating correctly.
Let me know the results please
ok, what Ill do is leave this question to remain open, so if the problem returns Patricia, let me know here at any time, this is no problem.
If you have continued problems, or would like any additional information or assistance, please do not hesitate to let me know.
