One For All remotes are designed to work with almost any television, including Samsung TVs. In most cases, you can simply point the remote at the TV and start controlling it. However, if your remote is not working properly, there are a few things you can try to fix the issue.
First, make sure that the batteries in your remote are fresh. If they are low or dead, replace them with new ones. Next, check to see if the buttons on your remote are working properly. If one or more of them seem to be stuck or not responding correctly, try cleaning the remote with a damp cloth. If that doesn't work, you may need to purchase a new One For All remote.
