Hi to all!

I have a Nintendo Switch OLED with a green background instead of dark background, after i´ve replaced the fpc of screen, accidentally i burn the original fpc.

I´ve tried with another working board, an the screen is ok.

So, i think the problem is in the board.

Somebody have an idea?

Thx in advice!
 
You should post some photos to show what you are seeing.

I'd also diode test the display connector's pins, reference values can be found on various posts or by viewing the OLED pcb in FlexBV or my OBV fork. Example:

Link to my post with the PCB files and the OBData to view the diode tests:

The green background is from a damaged component on the motherboard. Check around the display connector.
