So I am trying to learn how to solder and I opened up my switch lite to install an SX lite mod chip. I open the switch and took everything apart, and got down to the point where it would be ready to solder. I then touched it and it started making sounds, and then I noticed the fan was turning. I have absolutely no idea how it turned back on again but now the screen isn't turning on. The touch screen part works and the sound and buttons work but it also seems like the right d-pad button isn't working anymore either. (It isnt making any sound pressing it). I have put everything back in it besides the Metal guard thing And the heat pipe because I figured that stuff shouldn't matter when it comes to the screen turning on. I can't imagine I permanently broke anything because I haven't even soldered anything yet. Does anybody have any advice on things I could check? I unplugged the battery for now so the GPU won't overheat without the heat pipe or thermal paste.
