Is it worth repairing my HTC Inspire?

I'm sorry if this question has already been answered lol but I don't think my question is quite the same as some I've seen about screens so here goes...I was walking to work one day on a gravel road, my inspire which is always pretty durable and hardy fell on the gravel and the pointy rocks cracked it open...it worked for a few days and then no screen...I'm wondering if it's just the screen or an internal issue...is there any way to tell without spending money on repairing the screen? Right now there is only a black, cracked screen and no action....I am fearing the worst on this lool (also if you have other suggestions on ways to get a better smart phone at minimum expense, I'm very open to lol)
