Never done a blog before so this won't be brilliant.

I recently purchased an Xbox 360 from amazon for £195. It included a premium Xbox, and extra controller, GTA IV and two other games. It arrived yesterday which I was happy about. I spent ages unpacking it and putting all the wires in the correct places and I turn it on and it doesn't work. I have spent ages trying different things and the picture just won't come up on the TV. I am sure there is nothing wrong with the Xbox...
