Can I my soundbar after plugging wrong power cord of AC rather than D

Hi,

What is the make and model number of the soundbar?

Most probably the power board (or the power input section of the motherboard) has been damaged by the connection of the incorrect voltage supply.

You will need to open the soundbar and the check for any damage, such as blown fuses or surge suppressors and burnt out components etc.

Search ifixit for your make and model soundbar to check if there are any repair guides available that may help.

Having soldering tools and expertise and also a DMM (digital multimeter) might come in handy as you most probably will have to use them.

Post some close up images of any damage back here.

Here's how to do this.
