Could this problem happen due to bad LCD connector?
I've changed my friend's screen, when I reassmbled the phone I saw the screen was defective, showing colored stripes and stuff like that, so I changed back to the original broken screen of my friend and this is how it looked:

Could it be a crazy coincidence that I broke the original LCD and the new screen is defective or it looks like a connector problem?
Questa è una buona domanda?
