DTV mode unavailable on Samsung LCD TV

On my Samsung, doing a "reset" didn’t solve the problem, so here’s how I found my digital TV:

Launch the secret menu (put it in standby, then quickly press in this order: info menu mute power. The TV turns on and then displays the famous "hidden" menu).
Go to: 2. Option Table (Service)

=> Then, on the very first line "Ready", if it is set to "ON", you need to set it to OFF (with the right arrow).

Once this "Ready" is set to "OFF", press Power to exit the hidden menu, then turn the TV back on.
The "TV/DTV" and "D.Menu" buttons should now be reactivated (it no longer displays "Unavailable"): the internal digital TV is operational again.
To initialize the channels, go through the normal Menu and start a "Plug and Play".

hello, I have the same problem as you. there is a manipulation to do with the TV turned off, and you access Samsung's hidden menu.

in my case, I can no longer access dtv like you, but even after doing a reset, it's the same thing. I don't know what to do anymore... my plasma TV is 2 years and 2 months old!!! so no longer under warranty.

Good evening Mathieu,
I'm sorry but I don't understand everything...
Let's not talk about Numericable since you don't want or can't receive TNT through their cable network anymore.
You have an LCD with a built-in TNT tuner and you want to use it.
There isn't a multitude of solutions; it needs an external or internal terrestrial antenna.
That's all there is to it!
Once connected to the antenna (internal or external), you need to perform an automatic channel search in digital quality, and you will automatically be in DTV mode.
It's not more complicated than that.
Best regards.

Good evening,
The internal decoder of the TV works with a terrestrial antenna.
Then you need to perform an automatic channel scan.
Check out this post, it looks like your case:

See you!

Thank you for your response, Franck, but the problem does not come from the cable network, since since October, it has been working in DVB-T mode and no longer DVB-C, as evidenced by this link: https://forums.commentcamarche.net/forum/affich-11241371-televiseur-tnt-avec-reception-tv-par-cable or even the official Numericable forum. The problem mainly arises from the fact that I cannot switch to DTV mode; I have read on several forums that this happens from time to time and that it is sufficient to reset the TV, but I cannot find how to do it?
