Black screen but everything else works.

I bought a second hand macbook, still under warranty, apparently the last owner spilled some liquid on the equipment, causing a problem with the screen. Apple only accepts to do the repair if they change all the parts (Logic board, connector, screen), for me it's not feasible.

I can use the macbook with an external monitor without noticing problems, IO, camera, microphone, charging, keyboard, touch ID, everything works except the monitor.

Is it a good idea to buy the screen and repair only this part myself or is there a high chance the problem is in the logic board?

After you reconnect everything, start it up and using a flashlight resting on the display at a sharp angle do you see a faint image of your desktop and icons?

If you do then the displays backlight circuit needs repairs, otherwise you will need a new display assembly.

If your system has a warranty, I would let them fix it.

It has no details, but it was possible to notice a slight coloration of the screen. It looks like a high contrast of black and dark grey. I will add more photos to the initial post.

@edsonluiz - Well this is a new one for me!

Do you understand how polarized light is twisted by the liquid crystal display panel? What we are seeing is the T-CON logic within the display logic is bending the light for intensity but for some reason the color pixels are not being activated.

The bottom line here is the display assembly is bad!

I don't know how macbook panels work, unfortunately. Thank you very much for your help @danj, I think I will give a full screen replacement attempt, it seems to be the one with the greatest chance of success.

I have the same problem, but if I close the screen and back is works for seconds till it glitches back to this blurry black. Do you know what was the problem?
