Hi folks, first time posting, I hope you can help!
My TV has developed a vertical screen judder. It is intermittant. I thought I had fixed it by doing a factory reset, but it's come back again. When I do a picture test the sample photo appears perfectly, but when I exit that screen the juddering starts again.
Model: UE50EH5300
Software Version: T-MST10PDEUC-2004.1
