artifacts on the display. I think the problem is most likely in the display itself. But I would like to understand what is broken and what needs to be replaced. What leads to such a problem? What are your steps other than replacing the display?

Is that original display?
Did you test with another compatible one?

de, the display is original. The task is to repair it. The MacBook works fine with another display.

Is possible to change the T-CON board?

 

[ipetro]

why is there no image when replacing the t-con? is it possible to replace the t-con entirely? or do you just need to mess around with the chips? is there a link between the t-con and the display?

The memory placed on T-CON stores some adjustments.
Some are MLB specific; as you already know, that memory and display controller must be changed when replace entire LCD assembly on new models.
This avoids the artifacts on top side LCD.

I suppose that also display adjustments are stored there.
So you can try to change only the memory; or both chips.

Replacing T-CON board is also possible.
Not an easy job, but doable; I saw some video somewhere...
