I've had this TV for 5 years and 5 days ago the power went out. After the power came back on, the picture started to freeze and the TV started turning on and off. I thought maybe everything would get back to normal if I unplugged the power for a few minutes. Unfortunately, that problem hasn't been solved. But I tried something else. I reset the TV settings and returned them to factory settings. And I can say at least for now after 7 days everything is fine. Has anyone had the same problem and also fixed the error that way?
