TV Repair Questions? Ask a TV Technician for Answers ASAP
Hi, I'm Nathan.Sorry to hear that you're having trouble with this but I'll do my best to help you.
Those speakers can certainly blow out or fail, they are very small and don't have much room to move inside these thin tvs.
While it is possible to fix them, it is generally not practical to do so as the cost of the labor alone to get at them and replace ends up costing nearly as much as the tv is worth, and in the end you'll still have the same poor quality sound that the tv originally had.
What I'd recommend instead is turning of the tvs internal speakers from the sound menu, then hooking up an external system like a soundbar instead. The cost is minimal, less than you'd pay for repairs, and will give you much better quality sound in the end anyway.
