TV Channel Numbering SAMSUNG.

- The manual tells me to select menu and then channel. I can't do it. Channel appears grayed out. I can't click on it.

Classify them. You must have done the alphabetical sorting.

That's exactly what I'm trying to do. But I need help since I don't know how to do it!

No, it was a suggestion. You don't have HD and your screen is compatible up to 1080i. You would see a difference.
You need to go to the settings menu and check the channel list, read the on-screen instructions.

Yes. But the problem is that I always have to go through the list of strings to select what I want to see. Like
Can I reorganize all of this? I'm a beginner in this area, so I don't know much.

The way to do it varies depending on the brand and model. This function is often found in the same place as the channel search, in "rearranging channels."
If it bugs too much, reset to factory settings and reinstall everything. The manual is sometimes of great help.

I reset to factory settings. But nothing changes. Thank you for your help.

You need to go to the TV configuration menu. Otherwise, since you don't have TNT HD, get an adapter like this one: http://www.rueducommerce.fr/destockage/TV-et-Lecteurs-DVD/Television-Numerique-Terrestre-TNT/AKIRA/4855053-Adaptateur-TNT-HD-USB-avec-fonction-enregistrement-DHB-B36HR.htm it also works as a recorder, and don't forget an HDMI cable: http://www.rueducommerce.fr/Accessoires-Consommables/Cable-et-Connectique/Cable-HDMI/RUEDUCOMMERCE/2858359-Cordon-HDMI-type-A-male-HDMI-type-A-male-version-High-Speed-1m50.htm

Do I have to buy something to put the chains back in order?

Don't you have the "reorganize channels" function in the menu?
It's also worth mentioning that this TV (as well as the brand) is known for its poor build quality: https://www.lcd-compare.com/televiseur-SAMLE40R86BD-SAMSUNG-LE40R86BD.htm

No. Part of the menu is inaccessible (the parable).

The parabola symbolizes only the reception and not its type. Are you asked for a parental code? Sometimes, to access certain menus, you need to press two buttons at the same time. Nothing in the manual?

I unfortunately do not have the manual. The television was given to me by a friend.

I finally added the TNT Bouquet to favorites and organized them in channel order: TF1 as 1, France 2 as 2, etc. Thank you for your help.
