BEST ANSWER:

When I turn mine on there is an audible clunk as the motors engage, so if you are not hearing that then I would say it is not getting power. Make sure none of the power connections are loose and verify the wall outlet is supplying power and any power strip you might be plugged into is also switched on and supplying power. If it is all plugged in and you know it is getting power but you have a blank screen and no motor engaging sound when you switch it on I would think the problem is likely with the power supply and you need to contact customer support. If you know the outlet is providing power and you hear it engage when switched on then the problem is likely with the LCD screen and you should contact customer support for that.
