Yes, samsung tvs are will known for this but it is preprogrammed commands that give owners problems. The remotes have the wrong protocol, it one time it was the right one but samsung changed it. But your tv oem has the right protocol, and a learning remote shouldn't have any trouble learning theses commands.

Do me a favor, program a tv code not samsungs to the tv device. without erasing the taught commands, do the volume keys even work at all now?
