Deeply troubled 16inch MacBook Pro 2019... screen and motherboard replacement

Hi,

I am the sad owner of a 2019 Macbook Pro 16inch with 64GB of Ram, 2.3GHz i9, 8GB AMD Radeon Pro 5500M and 1TB of storage.

It has broken down and shows no image on the screen, there is some activity like the fan or the green caps lock light, but no touch bar and no external image via cable.

I live in Colombia (the country, not the state) and the certified Apple technician tells me that the motherboard as well as the screen must be replaced costing a little over 1900 dollars and taking up to month for ordering the motherboard with these specifications.

I am considering traveling to Miami in the US to get this fixed. Since I am in Colombia I can´t just go over to the next Mac store or even call in to ask the cost and time it would take.

So my question is: How much do this motherboard and screen cost? And is it possible to get it fixed in a couple of days?

I would love if anybody could provide this information.

All the best

Anton
