This phone will likely need motherboard work due to the fact that the replacement screen does not work and your original screen no longer works. Try taking off that foam-like sticker around the display connector, take another picture and then upload it. That should give me a better idea if anything important is missing or damaged, which right now I don't notice anything wrong. I hope this helps!
