Keyboard backlight broken after fall

Hello,

sadly, the backpack containing my laptop fell down leading to some issues now. One of those is that the keyboard backlight is not working anymore.

It doesn't seem to be a software issue - on both my operating systems, the backlight worked fine until the fall. After, it worked somewhat, often flickering, especially with pressure on the broken parts of the case. It does not work at all currently.

Now, I tried finding documentation on where and how the backlight is located and connected, but I sadly wasn't able to find any, seeing as the keyboard is not part of the maintenance manual either. Is it integrated with the keyboard connection? The keyboard works without issue otherwise.

If anyone has any ideas, I'd be quite grateful.
