Hi all.
First, I'm not familiar with working on this model board.
No video on internal panel or externally on any USB C port with a USB-HDMI adaptor that I've had working in other Macbooks.
No fans, no chime.
No signs of any liquid damage on either side of board.
Power rails seem good, CPU gets hot, USB hard disk gets flashing light on it.
Tried with another AC adaptor, both with and without battery connected.
Tried SMC reset.
Tried on external panel with internal disconnected, and tried other internal panels.
PPDCIN_G3H IS 22v.
PPBUS_G3H, HS_CPU, HS_OTH5V, HS_OTH3V3, S4_HS_TPAD are all 14.v.
PP3V0_G3H IS 3.4v.
PP3V3_G3H, S5, SUS all 3.7v.
PP5V_S5, S4, S0 all 5.7v.
Any suggestions appreciated.
Thanks.
