After a drop, no image on the touch bar, but the touch is still working.
Also, I can't install the os, is giving me an error.

This is the classic Touchbar issue and you can find a lot of info on the forum.
Use search function and collect data from different threads.

Disconnect internal LCD and test the machine with external monitor.
You can also disconnect camera connector from the shell only.
