Schematics of ProMedia 2.1 set of speakers (bluetooth version)


Recommended Posts


I own a ProMedia 2.1 set of speakers (bluetooth version). I bought them used out of warranty (my bad). After about one year of light usage one channel died and soon after the other one too.


Now my only choices are to repair it or throw it away. I own an oscilloscope and a soldering iron so I would like to attempt a repair. However I am not an electronics engineer, so reverse-engineering the board without schematics is above my pay-grade. But if I had the schematics I feel I could do it.


The schematics linked in this thread is for an older model: http://www.thompdale.com/bash_amplifier/New_2-1/New_2-1_bash_amp.htm


Does anyone know where to find the schematics of the new Bluetooth version?


I am attaching a picture of the sub-woofer board: https://photos.app.goo.gl/Tt6Ym6hESnwWdVo68
