Fixing a completely dead Marshall Stanmore Bluetooth speaker

Something unusually young on my workbench: this Marshall Stanmore Bluetooth speaker from 2014 is completely dead. In this video I'm going to rebuild the problematic section of the power supply. I found 3 forum threads in total discussing several technical issues and repairs related to this device: 1) Badcaps.net (English): https://www.badcaps.net/forum/trouble... 2) Mikrocontroller.net (German): https://www.mikrocontroller.net/topic... 3) Retrotechnique.org (French): https://forum.retrotechnique.org/t/pb... The hand drawn schematic shown in the video can be found over here: https://www.mikrocontroller.net/attac...
