White light comes on and the power on noise happens, but the light goes out after about a second or two and nothing else happens.
Had the same issue last night, but console eventually booted for first time and was on a couple of hours (including successful update). Tonight it just won't come on no matter how many times I try. No issue with power cables and I can see the amber light on the brick turn white when the light on the console comes on.
Hope someone can help.
