Nintendo Switch Lite - Black Screen but making sound - Let's Try to Fix it

Picked up this Pink Switch Lite from ebay, seller said that it works fine, but when the shoulder button was depressed, the screen would go off but you could still hear it. Upon arriving, it was just a black screen, nothing there at all, but after a bit of tinkering and a little look inside, this Lite is all sorted, a nice clean, quick fix and no real "effort" was required.
