So, I bought the Darth Vader lightsaber less than 6 months ago for Halloween. Took good care of it as a prop piece for my costume. When I was finished with it, I put it away in my closet for safe keeping. I took it out a few days ago and powered it up and it came on just fine, after a moment the sound cut out and now it will not come back on at all. I tried new batteries, cleaned the connections, troubleshooted as much as I could. The battery pack looks ok and I unscrewed the top piece to see if any wires were disconnected and all looks fine. Can't get the bottom half off as looks like one solid piece glued together. Has anyone had this problem or know a fix or something that I'm missing??? It powers up just fine, just no sound.
