Default [Q] Goophone i5s black screen

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. Its very frustrating as soon as I turn it on it just gives me a black screen then turns back of recovery mode doesn't work either
Thanks a lot guys.
