Thumbs down Asus Transformer Prime Dead

Hi

I have the Asus Transformer Prime since 1 year ago. I installed differents ROM's, the last was Virtuous ROM.

Last weel i tried to install Cyanogen. I deleted all O.S. and I couldn't start the tablet. Only I can see the Asus Logo, no recovery and no ADB because the PC didn't recognizes it.

Then, the battery ends and now it's no possible charge it, no start It, nothing!

Any recommendation, someone know how to repair and I send it?

Thanks so much!
