I have a 75" samsung Q70 that shuts off all by itself. I have been able to turn it right back on in the past. Now the red light under the tv keeps blinking and the remote does not work as well. I have tried all suggested fixes, unplug, upgrade software/firmware, re- pair remote. None of these have worked and now the tv will not turn on at all. It is only I have only had it for 2 months
Now the tv turns on. I did a full reset and software update. It is back to randomly turning off whenever it wants
Is the TV plugged into a surge protector or the wall outlet and have you had any power outages recently?
Does this occur when nothing plugged in to the TV? If still occurs then this will require service and you can send me a private message so that I may look into all options possible.
