Do I need to return this new phone screen?

I just bought and replaced my whole phone screen (lcd and digitizer) for my Samsung galaxy s5 but now suddenly my phone is doing this colorful static looking screen. Sometimes it will also make it look like the picture is repeating itself halfway down or will endlessly loop. Is this a faulty screen that I have and need to return it or is there possibly something else wrong? It doesn't always do it, and I'm typing this message from the phone itself right now, but when it does it causes the phone to sometimes have to restart itself.

This is one example I was able to catch. When I get a picture of the other times I will post them as well. If I try to take a screenshot it doesn't work and the phone takes a screenshot instead of what it would nor ally be and not glitched like that. If I poke around, buttons are still responding where they she be despite the picture being distorted.
