I just bought a Q6F and I'm having the same issue. Seems to do it more frequently when watching 4k. Mine doesn't have the separate box like everyone is talking about. Please help!!
I'm having this issue with my QN55Q7FAMFXZA. It was purchased in June 2017. I guess I'm out of luck. Is there any flexibility with Samsung support on replacing parts free? I do not think I should have to buy a new cable at $200 or a new box at $600 for a flagship model TV that is 18mos old.
Off Topic but curious do people see any color flashes with QLED 2017? By the way since owning this tv since October 2017 I have never experienced the issue with tv turning on and off.
Same here. Brand new Q7 constantly restarting out of the box. Called customer support (terrible btw - foreign call center employees reading scripts, totally clueless). Only option given was to send it back and re-order. FedEx Freight guy told me it was the 10th one he picked up that day. This is a systemic defect and I think a class action is imminent. Nearly a month later and no refund from Samsung BTW.
