I plugged my Sony Srs- xb 30 portable speaker into my computer charger by accident. That sent it a lot more power. The portable speaker never worked afterwards.
which part should I replace?

Hi @geoyachts ,
Most probably the power management circuit in the speaker has been damaged.
You will need to open the speaker and check the components around where the power port is connected to on the circuit boards to assess what damage has occurred
Here’s a link to the ifixit Sony SRS-XB30 repair guides. These will help you to open the speaker to check for the damage.
Just a heads up, if a component is damaged and it cannot be recognized what the value of the component is then it may be difficult to fix without a schematic diagram of the speaker. I can’t find one online, you may have better luck.
Nevertheless, if you do spot the problem or even if not, post some close up images of the boards back here. Perhaps someone may see something that will help. Here’s how to do this. Adding images to an existing question
