2017 model Samsung 7 Series (49) randomly powers off. Constantly needs to be turned on again. just started this month. "Mobile On" option is off. "Timer" option is off. No setting for "External Device Manager." I dont know if the cable remote has started to do this. I dont seem to find any place to disconnect a universal remote control if thats what the cable controller has started to do?
I'm sorry to hear that, do you bt chance have the tv plugged into a surge protector? Does this occur with it plugged directly into the wall? And does this occur with the batteries taken out of the remote?
Please keep me updated!
