The sound of static coming out of your television speakers will quickly alert you that there is a problem you need to address. The first step is to troubleshoot your speakers through your television's audio menu. However, if that doesn't fix the speakers on a TV, you may need to open up the television and replace your television speakers.
Unplug your television and lay it, screen down, on a soft surface such as on carpet or on a bed.
Video of the Day
Remove the Phillips screws from the back of the television shell. Make sure you unscrew all of these screws before you try to open up the back of the television.
Pull the back cover off the television set. If you have a hard time pulling the cover off, you may have left a screw in place or internal wires may have snagged on the cover. Carefully remove them until you can take the cover off.
Replace the old speaker with a new speaker that matches the old speaker in impedance. For example, your replacement speaker should have the same ohms or volts as the old speaker does. You can find this information on the magnet on the speaker. Remove the old speaker, taking notes of how it was connected, and then install the new speaker the same way the old one attached to your television set.
Reset the television cover and replace the screws you previously removed.
Turn your television back up on its base, plug it in, and turn it on to listen to your new speakers.
Things You'll Need
Removing the back of the television set exposes you to the tube, which, even if the television is unplugged, can shock you. Take care not to touch the television tube when you replace TV speakers.
