Hello, I bought a faulty 3DS with the intent to repair.
The console couldn't power on, which I fixed, however the top screen has image, but no backlight. I checked the ribbon cables and the connectors, but i couldn't see any tear or damage.
If somebody knows what could cause this problem or what should I check on the motherboard, I would appreciate it.

Hi!
Yes, this could be caused by the PMIC failure.
Please see Testerfan’s post here: https://gbatemp.net/threads/3ds-backligh...
Another possibility is that the backlight inside the screen is broken.
In this case, you need to test with a new screen.
Please let me know how it goes :)!
