Arrived with only minor liquid damage on pin 45 PP5V_S0SW_LCD of lcd flex and connector on screen. Replaced both but still nothing on the screen. External works fine.

What should be checked next? Could it be bad cpu now?

Try full known good (compatible) LCD assembly.
If still the same, very likely damaged CPU eDP output...
