So my speakers worked perfectly fine last night, but as I turned it on today, it stopped working. Here is what is happening, I turned it on, but it does not look the power is "strong" enough to keep it alive. I replaced the power cords, and the second cord looks like it is slightly "stronger". The LED does not power on, but the Bluetooth light flashes for a moment. Also the hissing sound is very low, please let me if you can help. THANKS!
