Was not getting past 5v. All the charging chip diode settings were good so I reflowed left side and 20v back but no life. DFU restored and went through properly but still nothing. CPU voltage is at .995V so I think that's proper? connected drive is not showing any data activity. I did a PRAM reset on it while it was connected to configurator and the lock screen went away and came back so it looked llike it PRAM reset but I didnt have the speakers connected at the time. Regardless currently no data activity.

No liquid or anything it just quit working while customer was using it. Sometimes it gets stuck at 5v and no Amp draw but if I SMC reset it or put it in DFU will go back to 20V again.
