How to fix a Blue and Black Screen on Iphone 4?

I dropped my iphone 4 today and unfortunately I got a blue screen with black vertical lines… I can't do a hard reset because my lock button has been broken for some time now.Am I totally out of luck or is there any way I can fix this. Would anything with my computer help? Thank you very much for the help its greatly appreciated.

Sorry, you've broken your iphone and will need to replace it. This happens when the processor has been "Bruised" and stops sending the correct data to the display. The processor basically runs your entire iphone, so you're screwed. Sorry buddy.
