Hi there, How can I repair my iphone 4s screen?

Yes, the best places for instruction and details on that issue is IFIXIT or YOUTUBE, and kits are available on Ebay, it requires patience and dexterity with small parts and tools, but is doable, I fixed mine and others

This is far outside the scope of this forum.
I suggest you post this to an iPhone forum.
