Soundcast

Out of the blue, my Outcast stopped working. All of the control buttons are unresponsive and the unit will no longer turn on. I purchased it in July and it worked fine until a couple of weeks ago (the sound is AMAZING when it works). The unit has not been abused in any way. The unit is fully charged, plugged in, but will not respond. After a couple of weeks of not working, about a week ago I pushed the button and it turned on. It has not turned on since. I see that other users have encountered the same problem. Has anyone found a permanent solution to the problem?
