Chosen Solution
We had our speaker sinc’d up with 2 devices and then cancelled one out and added a different one. The speaker was working fine. We did not use the speaker in 6 days and when we turned it on today we get 3 flashing green LED lights by the on and off button. They blink for approx 2minutes and then the system shuts off, blinking stops and it is dead? Our devices say paired but the speaker is completely dead? We have power in the outlet and the cord and we have only owned it for 2months? What could be the problem? Is there a fix?
Suggest soft reset….➕ And center button…. If you are sure it is getting usb power….ie charging lights are cycling….but still will not turn on you could try Disconnecting power to hard reset it as such See here …… Fixed. I our speaker had several buttons pressed at once and it ‘crashed’ Would show charge lights but not charge, charge continuously never stop….overnight….(I knew it had 50% charge in battery) Would not turn on…dead…100% Solution…disconnect internal batt from motherboard for a few secs…complete power down…..now all ok…
