Default Not turning on....

Just received my Xperia Tablet Z from Amazon today...and I can't get it to turn on.

I press the power button...nothing. Hold it....nothing.

I have done the Sony PC Companion and did the repair, and when I plug in the tablet I get the Sony logo and that the battery is half charged. When charging the tablet, it has an amber light (sometimes red?).

Any assistance would be appreciated. Amazon will not replace the tablet as it is has gone up almost $100 since I ordered it, they will only refund it and make me pay the difference.
