Dear all.
I'm a less knowledgable member who would appreciate some guidence.

I have a Samsung QE55Q70RATXXC that works perfectly in "shop mode" but in home mode it restarts, Intermittantly.
With intermittant I mean the TV can work perfectly for a week and suddenly start to restart. Before the restart it may reach different stages. Sometimes it restarts when the "QLED" start screen shows up and some thimes it restarts after hours, and everything in between.
When the restart occurs, the screen blacks out leaving a light area alomng the edges fading...
