Harman Kardon soundsticks2 no sound just a blue light

Hi everyone here at the ifix it HQ..

As the titel of my question, my Harman Kardon soundsticks stopped working out of the blue?

Nothing bumped them ore water etc, it did happen once before but they came back to life?

Now power is working i get a blue light, i tried holding the both volume buttons holding them simultaneously and individually, nothing

Also tapping on the jack plug i hear nothing, i am guessing the main board has a issue, i live in spain ( ibiza) and the electro repair shop doesn’t fix them they told me spain doesn’t import parts anymore for this brand so they can’t get replacements?

Anyhow i will try and find a replacement board and do it my self but was wondering if any of you fine folks here maybe had some info about this ?

Thanks in advance

Have a good day!
