My iphone screen won't work?

I was using my phone normally and it started going faulty, I couldn't click anything etc. So I decided to lock my phone and then unlock it again expecting it to be normal, instead my screen wouldnt come back on. I get vibrations and notifications, however the screen won't come on, it's just blank. I googled it and they suggested I hold down the home and power button together, I can't do this because my power button is broken (I have the world's faultiest phone) is there anything I can do to get my screen to work again?
