RP2040 installation results in a black screen on the Nintendo Switch.

Hello everyone, I welded a Picofly on Switch V2 and when I start it, I have a backlight but no image.
But when I touch the screen, I hear the sound of the Nintendo Switch.
But when I put it in the dock, I have an image. Everything works very well except for the screen.
After inspecting the LCD connector, I found that everything is fine on this end.

I need help please

Maybe it's nothing but there seems to be a pin missing here :

If you didnt remove the LCD cable when installing the chips it should be fine(normally no need to remove LVDS). Check and upload pic around the max77812(south of cpu) or cpu metal shield around if any broken trace when removing shield bracket.

There are new pictures here that are very clear.
