I have a Samsung UE50NU7470 TV. Every few days I go to switch the tv back on and all my tv channels have disappeared. On the TV guide it says no information and then I have to manually re tune the tv to find all the channels and store them.
This happens every few days after watching the tv daily. I’m tuning the tv to “Freesat” on the tuning options.
I'm having this issue too on a new 49" QLED model. I can replicate the fault by going to the Samsung TV app. Once this app launches and starts to play back content, all freesat tunings option are lost, in fact it looks as if the entire satellite tuning module crashes. If I go to the setup menu and go to broadcasting, all options are greyed out and I need to factory reset the TV to restore it and go through the tuning process again.
Thank you Boidy so much! I've been getting this problem intermittently since I bought this TV nine months ago, but I could not replicate the problem on demand. I had previously contacted their chat support and been advised to seek help from a satellite engineer. I have now a shiny new dish with the same problem on my TV and £200 less in my bank! Thanks to your repeatable error I have just told Samsung Chat Support the exact problem again, referencing this thread and your reply specifically. (I don't even use the Samsung TV app, so perhaps other apps cause the problem as well, nevertheless they have to fix it now). Their reply "Thank you. As I've reported this matter to our product specialist, we are processing an advanced update for this TV model about this issue so it will be fixed immediately. We don't have the exact time frame of the update but don't worry, this update will not take that long."
