What is Viera Link? Viera Link allows the control of other Panasonic home AV devices via the television remote control. By pressing the Viera Link button on the television remote, it is possible to turn on and navigate the menus of other Viera Link equipment. Please note, Viera Link requires an HDMI connection between the television and the external source. More control functions have been added with each new generation of Viera Link compatible products. However, it is important to note that the newer functions only work if both products are from the same year of manufacture. Therefore, if an older source is used with a newer year of television, only the older functions common to both years will work.

Try this.

You can do this from your remote control! Look for the button that says, "menu," and click on it. Here you should see a list of the various functions of the remote and television. Here we are looking for the "audio," key. Depending on your cable service, this key alone may show many options. The one you are looking for is "closed caption." When you locate the closed caption key, click on it until it says, "off." There you go, it should be a breeze!
