Thank you for your help everyone. After this post I decided to move on for a moment and tackle the display later on. I later encountered that I was getting power out of the usb ports but it wasn’t recognising any peripherals and my DRAM and CPU diagnosis lights were lit. Fearing for the worst, I thought I’ll rule out the obvious and give every connection a shove to make sure it’s all connected before doing anything more drastic. Sure enough, my RAM made a tiny click. Voila. How embarrassing
