2 year old Samsung QLED TV Q55T being watched as normal suddenly started turning on and off non stop for no reason. Seems to me like a background update got altered. Samsung engineer stated the screen is damaged. How on earth is that even possible? And the bizarre thing is, they want to replace screen for £500. How much is the TV worth now that I'd want to spend that on a TV. It seems to me a software problem and not a hardware issue.
