iPhone 4 screen not turning on after replacement

Hey guys, my iPhone 4 screen had an issue where the screen would only show blue lines, so I decided to replace it. After replacing it, the screen wouldn’t turn on at all, but when I put the old screen in, it showed the blue lines. How do I fix it? All help would be appreciated!

The most likely cause for this is the new display being faulty in some way. Where did you get the display from?
