[Q] Tf300T hard brick, screen won't go on topic

Hi people,

So, during flashing the stock rom on my Tf300T (which I've used before) the installation stayed on the same spot for over an hour. I thought it was a good idea to turn off the power and do it all over again. Unfortunately the device doesn't turn on anymore. Or at least, the screen doesn't. It gets recognised by windows but not by fastboot. Is there anyone who can tell me what to do?

Thanks in advance!
