Sucks that they tell you it is something so easy! But if it was under warranty it is better to send it in anyway.
I know I was having issues with my custom built saber, it would come on but anytime you would clash it the saber would shut off. I took the whole thing apart and rewired it with a new soundboard, it did the same thing. Only thing left was the battery, changed that and it's perfect LOL.
Yeah, I didn't want to mess with this one and screw with warranty while I have it. Glad to know it wasn't the accelerometer, if down the line a wire breaks again and causes this it's good to know that can be fixed.
I actually got an Obsidian Lite setup from eBay, and when I received it and turned it on, it just made a whining noise at me. I thought the board was messed up but changed the batteries and everything is fine. Low batteries really mess with everything haha
