What to do if your Sony sound bar fails?
Grab a soldering iron and carefully remove the failed capacitor. If you don’t feel comfortable doing this task, you may want to hire it out to a geeky friend : ) Go to your local electronics repair shop and buy a new 470uf 16v 105c capacitor. Panasonic, Nichicon, Rubycon and Nippon Chemicon are good brands of capacitors to buy.
Can a capacitor be replaced on a Sony sound bar?
Others have reported success by replacing the capacitor even when it doesn’t show signs of bulging or stress. Remove the board from the unit and locate the C914 capacitor, replace it (or have someone replace it for you) and see if that fixes it.
