IPhone 4s screen replacement has black vertical and horizontal lines. Can I fix this?

I dropped and cracked my iPhone 4s's screen so I ordered a new one. I installed the new screen and turned on the phone only to find that the screen will only have black lines going up, down and across. You can see some color coming through from behind the black lines. Is this a faulty screen or is there something I can try to do and fix this? I tried plugging my old broken screen back in and it works fine.

Honestly it would be cheaper to get a new phone altogether, the iPhone 5 is now free with a contract

  • Vertical lines down my iphone screen? I woke up this morning and checked my phone, only to see that I have about 10 vertical white lines going down the front of my phone, they don't go either, even I'm on facebook; they're there, same when I go on camera. I restarted my phone but they still won't go, does anyone know what this is?

  • My iPhone 6S has varied colored vertical lines on the left side of the screen? My phone has been cracked for a bit at this point, but it had been working completely fine up until today. I turned on my phone to see these vertical colored lines leaning towards the left side of the screen and taking up around 2/3 of it. The right side is working perfectly fine. Also, when I use the phone, it clicks random apps without me clicking on them. I tried to hard reset, and nothing worked. How do I fix this?
  • My iPhone 4 has blue vertical lines down the screen? So, I bought this iPhone online about a year ago, cracked these screen once, had it replaced and now all of a sudden it has these blue lines running vertically down the screen. I didn't drop it or anything, I still am getting text and email alerts as well, so everything is working fine, just the screen seems shot. No clue what to do, anything helps if you know about this, thank you!
