A20 with NAND and preinstalled Android doesn't Power on

[MAC666]

Hi,
Sorry for my Bad english, I try to make IT Short 

I bought auf A20 with NAND and a preinstalled Android and VGA Adaptor. My Power supply has 12V 2.5A.
I habe noch other things like USB cable original something.

I am New to this...

If i connect the Power supply the Red Power LED Turns on, nothing happens...
No Screen on VGA or hdmi... tried Power Button for 5 secs and more, Pressed every button, nothing happens....

What can i do? I habe noch Internet connection AT the Moment except smartphone.

Help!  Thank you!

Maybe you're not waiting long enough.  On first boot, Android takes quite a while to start up (minutes).
If you turn it off too soon, you could corrupt the 4GB flash (then you would have to reflash it with LiveSuite).
It easiest if you have a USB - RS232 converter connected from UART0 on your A20 to your PC so that you can see the boot messages.
