Nothing? No LEDs light at all? Then the board or power supply has failed.
edit: You must be more specific than "nothing" if you want help. Do you get any output on the serial monitor? I recommend adding some serial output to your setup function so you can troubleshoot that section.
Did you try these devices separately? Does the ethernet work ok if used alone? Does that TFT display have a microSD card slot? Is there a card in the slot? What pin is the SD slave select on?
