[NINTENDO SWITCH] Black Screen with backlight

[Dula]

hi everyone, my technician soldered the rp2040 chip

after soldering it he told me that the video on the Nintendo was black and only worked if connected to its dock

desoldered the rp2040 chip from the console and changed these components but the problem persists

he technician sent me these photos which you can see from this link

he indicated to me that he replaced these components without success:
- pi3 video chip
- FPC video connector
- Screen

Can you help me?
