Switch Lite Blue Screen

Hopefully someone can help me out a bit…

I bought a pretty decently priced Switch Lite off ebay and it has/had the blue screen of death. I say had because now that is not happening, but instead when I turn it on, I have the backlight showing but no screen. I would hate to take mine apart to swap parts if I don’t have to, so maybe someone can give some insight. To give some insight on this console, I can tell it had been dropped on the top left corner. It also had some very minor corrosion near the sd card and a small spot on the left controller board. I was able to clean this up. I’m in no way an expert, but I have trying to learn how to diagnose and fix issues. I attempted a reflow of the CPU based on research, but I’m not sure if I did it long enough to make a difference of not. Any information is welcome and appreciated. Thanks!
