Having some issue isolating an issue on 5v_s0. No liquid damage, no visible damage. Sent to me, orange light, no boot. Opened it up, no fan, tested no 5v_s0. 3v3_s5 present. Any ideas. Tried a monkey see monkey do at u7200 and changed it. No s0 at pin 16, ppvin_s0_cpuvr_vin=8.56v. There looked to be some discoloration around the chip, so that's what prompted me to switch it out. No such luck. Ideas?
