Hey everyone, so this is my first electronics project and I have to say I definitely learned a lot. I bought a 3DS XL for $35 because the top screen was cracked and needed to be replaced. So I followed along with YouTube videos to replace the screen. Unfortunately, I ran into a little trouble:

I broke the ribbon cable for the camera. I didn’t realize it needed to be oriented the correct direction while being inserted back into the hinge so I was trying to gently twist it the direction I needed it to go to plug it into the connector but it ended up ripping

The tiny white hinge piece came off for the wide ribbon cable connector for the lower LCD screen. It’s way too small for me to put it back on, unless there’s some trick I don’t know about.

So here’s my situation: after getting everything back together, when I press the power button, the blue light comes on, both screens light up, but only the top screen has signal (and looks beautiful by the way so at least that part worked). The bottom screen stays backlight but black. After doing a bunch of reason, it seems to the the black screen of death? I’ve heard it could be because of the missing hinge piece not pressing the connector down, so I rolled up some TP and covered it in electrical tape to try to press it down. I’ve also heard it could be because the camera no longer functions. I’ve also heard it could be because the magnets are stuck in sleep mode for the lower screen. I’m not really sure what to do at this point and need help. Which ribbon cable for the lower LCD contains the signal? How do I fix this problem?

I had this problem with my original DS. The problem was solved when I realized that the ribbon connector wasn't firmly seated in the slot.

I had a problem with the 2011 3ds back in 2015 where my bottom screen couldn't work.
