Hey guys, I've been wandering this forum for a while but only recently joined. Anyway, I have an MR Luke 2005, and for some reason the sound won't work. The LED's all work fine, but there's no sound at all. Now, this saber has had battery leakage at one point and the contacts were pretty dirty. However, using an old toothbrush, I was able to clean them and the saber started working perfectly again. But now the sound won't work. Any help would be appreciated.
