How to get rid of static screen when I start my PS4

I'm very new to this so Im sorry if this isn't a good place to ask this. But I'm worried about my ps4. So normally it's 100% fine with no issues. But today I was watching a DVD on my ps4 and after it was over I turned it off and my roommate and I played a card game literally right next to the ps4. Now I have no choice but to keep my ps4 on the ground for now because I have no room anywhere else to keep it. And I happened to be sitting next to the ps4 as I play the card game. So I look down and I noticed the DVD was very slightly sticking out and the light was on. So I take the dvd out and I turn on my controller like normal. But when my ps4 starts to turn on my tv is showing nothing but static. I unplugged my ps4 and turning it on again but again nothing but static "snow" I'm not sure what I did wrong. And like I said my ps4 normally works fine. And was even working perfectly about an hour before the issue.
