This arrived with minor liquid damage in Q5240 area and pin 1 of JP600 with no power.

After reflowing corrosion in Q5240 area board was working again but after a few minutes screen went on and off a few times and now board cant get past 5v. Screen cable is burnt.

Diode mode on LPD_INT_AUX_C_N is 0. Does it sound like 50v from backlight killed the CPU?

Do you have short to ground at LPDP_INT_AUX_C_N, w/ and w/o LCD connected?
You may need to remove JP600, to discard it.
