Are you still needing assistance?
Unplugged or just off via Power Button?
Thank you for the information @Mike wolfe, if the problem returns could you do me a favor and run a picture test on the TV and let us know the results?
Problem returned today
Ran picture test
Problem was prevalent in all 3 picture test modes
Please get that to us as soon as you can.
Could you send us a private message with your model and serial number? http://bit.ly/2ihPL97
