PPDCIN_G3H at J7000 - jumping between 16.51 - 16.68V
R7012 measured onboard - 56.2k
D7012 - not open. Tested in continuity mode between R7012 pin 2 to R7010 pin 2.
BUT with my sharp eagle eye I saw that pin 2 of D7012 had the smallest oxidation I have ever seen. Replaced it and machine works again.
Thanks for your help!
