If you have a Samsung TV and want to use it as a center speaker, there are a few things you need to do. First, make sure that your TV is connected to your stereo receiver. If it's not, you'll need to connect it using an audio cable. Once your TV is connected to your receiver, you'll need to set it up as the center speaker. To do this, go into the menu on your TV and find the Sound or Audio settings. In these settings, you should see an option for Speaker Setup. Select this option and then choose Center Speaker. Once you've done this, your Samsung TV will be set up as the center speaker in your home theater system.
