Electronics Repair Questions? Ask an Electronics Technician
Hi there Bill and welcome
What is the make and model of the device that is giving this error?
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
