Hi I have an 820-00850 with liquid damage. Display connector is a bit burned< i assume thats 25v into the CPU. Is there a way to test the CPU and I can make sure it's dead? What resistance to ground should I measure?

Usually EDP_INT_AUX_N line is affected, because of proximity.
Compare diode mode to ground on all data lines of display connector.

Board is dead, or has external video, USB activity?
