Razer Blade 15 (2018) Screen Flickering and Touchpad bulging

So within the last month after using my Razer Blade 15 for extended periods of time for simple tasks (ie browsing the internet, typing on word, recording music, i don't really use the laptop for gaming) the screen starts to flicker exactly like in the video below (not my video/laptop). This usually occurs after maybe 3-4 hours of constant use and goes away if I turn the laptop off for a few hours. does this mean I'll have to get the screen replaced? If so how much does this cost since I am no longer under warranty? To be specific its the 14.0" 4k UHD with capacitive mulit-touch screen. This morning I noticed that the touch pad is no longer flush with the right and left clickers. I showed my brother and he mentioned it could be the battery bloating underneath and it needs to be replaced. If that is the case where can I get a replacement battery? https://www.youtube.com/watch?v=nKvDS01dDJM
