I had this problem, too. The red light is flashing when you hold power button is to signal that the battery is disconnected. This issue is caused by poor design. The magnet from the middle speaker sits on top of where the battery connects into the circuit board, thus pushing against the connector and unplugging the battery. This can be fixed by taking the speaker apart and then you have two options. Option 1: If you know how to solder you can solder the wires into the board, bend in a way where the speaker won't hit them. Secure with electrical tape and reassemble. Option 2: There will be a red female connector in the center of the board where the battery plugs in, disconnect the battery and pull on the plastic connector on the board until it pulls free from the board. You should now just have two pins sticking up and you just needs to simplify reconnect the battery being mindful of polarity (what is positive and what is negative ).
