I have an Acer xb270hu, bought it second hand maybe like 3 years ago. It’s finally giving out on me, sometimes half the screen would get these green lines that go through it vertically wherever there should be black. This happens after approximately 10 minutes of use. Recently it started having similar issue on the other half but with other colors getting stuck on the screen. Because it only happens after some use and not on boot, I’m led to believe that it is a cooling issue and or maybe something might be loose.

I was wondering firstly if anybody could tell me or help me open the back panel so I can take a look around and secondly if anybody had any ideas or tips. I appreciate any help, thank you
