The red version Gameboy looks a bit unusual with the light gray lens. Originally there should be a darker one on it. Regardless, the important thing is that it works well again. have fun with it. I also converted a DMG with the slightly larger IPS display (from Funnyplaying). I am also very satisfied with the image quality.
I will perhaps circle back to that. Right now I 'just' wanted to have a working screen. What I did do: reflow the components on the flex cable using hot air. No improvement. So I guess the problem is internal to the screen.
