I have the same problem. Only Off Timer. No On Timer. I got Q60T 2020 model. Don't understand why the latest model is missing such a basic function. That makes the smart TV stupid. >.<
I have the same problem and really miss this feature at my CG85Q80T. I have 5 generations and sizes of Samsung TVs - that's my first one without TimerOn. I also tried the SmartThings-App with rules, but it didn't work. I am really sad about...
Also some values for the timer off missing (90/150 minutes) ...
And I don't like the RF-Control - good that the old one still works with the new TV.
Same problem here in my Samsung UN55RU7150G.
This is really disappointing. I remember I had an old Samsung standard TV bought in the 1990s that already had this option, and new Smart TV models can't?
This doesn't make any sense to me.
