I have the same prob but the red light is on it has done this a few times before and we went back later and tried and it came right on now the red light comes on but we have waited and this time it is not coming on. I am a computer tech if I knew how to get it apart without breaking the case I could fix it . Does anyone have a pic of how it comes apart. Thanks Norman
