[Q] Goophone i5s black screen topic

I have the latest goophone i5s not the lite one. Anyways I hadnt done anything before hand when all of a sudden it powers off. I went to play it in again and now it's just giving me A black screen. Should I take out the battery and it put it back in again. I tried installing a new rom, but because the phone didnt work. I couldnt connect it to my pc? I have done nothing to make it bricked
Thanks a lot guys.
