Wow, a broker Flip 3 is a bummer as it is a pretty cool take-along with great sound. My wife dropped hers today and a component came loose inside and was rattling around. All indications showed it should work but the Bluetooth function wouldn't couple. I took it apart using the awesome "battery replacement" instructions to help me to disassemble it. When I opened it, I found an electronic component (a choke, I believe) had come unsoldered from the force of the impact due to inadequate solder from the factory. The component was labeled "1R5" (see component in picture of step 5 for the battery replacement). I carefully soldered the component back on the circuit board using a Weller 35 watt soldering iron set-up with a small blade tip, and voila! , it works again and sounds as good as it ever did. Piece of cake!
