Hi, this 'QUICK VERSION' repair video shows me attempting to fix a BOSE Bluetooth speaker that has a flashing red light fault. If you want the full length version please see    • Trying to FIX: BOSE SoundLink Mini II...  
Remember that this is just for entertainment and I am not an expert in these repairs. The processes in the video may not be the best way, the correct way or the safest way to fix these things.
I do love fault finding and trying to fix broken things so I hope that comes across in this 'Trying to FIX' series.
Many thanks, Vince.
