I had not used my Anker A3143 Bluetooth speakers in several months. All that time they have been plugged into a USB power block. Today when I went to try to use it (pair it to a new device) I found that the LED on the power button was flashing yellow very quickly. The speaker does not power on unplugged. It will not respond to any button pushes and does not even play audio connected through the aux audio cable.
Does this mean it has died somehow? It was not a cheap device so I hate to have to discard it!
