Welcome riarock, glad to have you in the forums!
Although andPHAN is right i would be more than willing to help you address your problem.
I would suggest to connect your phone to your computer and try to retrieve any and all information you can from it, this is really your only option as the screen isn't showing up for you.
I wanted to ask a question too, is the boot screen showing up and then going black once it boots up or what?
Thanks for joining and enjoy your stay
