hello all, ok so my daughters 3ds stopped working one day. when you turned it on the blue light came on then the thing went straight off agion. today after 3 months being in a draw we turned it on and it did the same thing. but here is the weird bit, when I held the console upright and turned it on its come on working perfectly, but when its laid flat and turned on it instantly turns off again.i sent to a repair shop 3 months ago and the said it was un-repairable. does anyone have any ideas?
