Test with known good LCD assembly.
Looks like bad LCD...

If you locate the problem as being the LCD assembly, no way to repair it.
Unless you want to change LCD only.

I understand that the problem is with the MacBook board. replacing LSD is easy but expensive. 
I just need help understanding what is responsible for what on the display board since there are no such circuits.
after replacing the entire board from another display of the same model, it leads to image loss. when replacing a large chip to artifacts. As I understand it, there are some microcircuits that need to be transferred to a new board . I will be glad to receive any help and information specifically in repairing display boards.

Usually the DisplayPort controller and its EEPROM.
I think we have a similar thread on the past week on the forum.

Yeah, the biggest chip.
Its EEPROM should be close to it, possible on the opposite side.
Search with Google for some marking codes...

I searched on Google but couldn't find it on Google! That’s why I’m asking and took a photo because you are a high-level master and can determine where the EEPROM is located and what it looks like. Your motto is to help me fix the device quickly. I can’t search for information for days with Rossman Group behind me)))
please tell me where is this EEPROM)

I can't read any marking code on these chips...
4GDK / N622 may be the EEPROM; or 6CM7WI...

Do I understand you correctly that you cannot transfer only the display port, it is also necessary to transfer the EEPROM, otherwise it will not work?!
Some LCD dependant parameters are saved into EEPROM.
So the EEPROM is paired with LCD.
Don't forget to make backup.
