Repair Vizio Soundbar - Video

Is your soundbar broken? Does it ompletely fail to turn on? This seems to be a common problem with the Vizio S4251w-B4.

This problem has actually happened to me twice on the same soundbar — I’ve done this project two separate times now. Because this soundbar continues to break, there’s a good chance that there’s a more significant issue going on with the power supply as I keep frying the same capacitor. This, to me, suggests that it’s not a cheap or weak capacitor problem but that more juice is getting sent to the capacitor than is supposed to. However, I’m not fixing that. I’m simply replacing the broken capacitor. if you’re looking of a cheap and easy fix just to get by, this has worked for me.

Tools & Parts

To complete the work, all you’ll need is a phillips screw driver, a soldering iron with very basic / beginner soldering experience, and a 470uF 16V capacitor. Let’s get going.

  • Phillips head screwdriver
  • Soldering Iron
  • Solder
  • Snippers
  • 470uF 16V capacitor
