Came in with light corrosion around the edges and the usual places, replaced two of the CD3215's and one of their FET's to restore 20V, u7000 area was looking pretty rough so I replaced it for reliability if nothing else. Charger only pulls .01-.03 amps.
at U8200
PP3V3_SUS = 0V
PM_SLP_SUS_L = Pulsing
PP_3V3_S5 = Pulsing
with U8200 removed
PP3V3_SUS = 0V
PM_SLP_SUS_L = 3.31V
PP_3V3_S5 = 3.31V
Any ideas what to look at first in the PP3V3_SUS line?
Many Thanks
