Are you tired of straining to hear your favorite TV shows or movies due to muffled sound? You’re not alone. Many TV owners experience this issue, and it can be frustrating, especially if you’ve just invested in a brand-new TV. In this article, we’ll explore the common causes of muffled TV sound and provide you with practical solutions to enhance your viewing experience.

How do I know if my TV’s speakers are blown?
If your TV’s speakers are blown, you may notice a range of symptoms, including muffled or distorted sound, a lack of bass or treble, or a hissing or crackling noise. You may also notice that the sound is uneven or unbalanced, with some frequencies sounding louder than others. Additionally, if the speakers are blown, you may notice that the sound is not coming from the speakers at all, or that the sound is coming from only one speaker.
To confirm whether your TV’s speakers are blown, you can try a few tests. First, try turning up the volume to see if the sound becomes clearer or more distorted. If the sound becomes more distorted, it’s possible that the speakers are blown.
