Hello!
I have green light , fan high speed, no chime,no video.
PPBUS_G3H OK
PPBUS_CPU_IMVP_ISNS OK
PPDCIN_G3H OK
PP3V42_G3H OK
PPVCORE_CPU ok
PPVCORE_GPU OK
PP3V3_SW_LCD voltage= 0 Volt.
F9800 is OK with 12 Volts.
LCD_BKLT_EN = 0 Volt.....
LVDS_DDC_CLK = 3.3V...
R7005 & U7000 replace....
I have desoldering C7015 and the capacitance = 1010pF, normaly 470pF...., must I replace too?( all SMD ceramic capacitors around U7000 are ok except C7015 ...)
So now PPDCIN_G3H was low voltage, I decide to desoldering F7040 (always low voltage)
I desolder U7000, and PPDCIN_G3H= 17V
Now mesures of resistance around U7000:
So I must replace R5280, R5281 (1.985Ω)????
replace R7015(56.5KΩ)?
replace R7005(4.81KΩ)?
OMG.......:(......
Now I realize.
So sorry for my mulimeter (and make you lose time, I hope you have a good laugh !!!)!!!!!!!!!!!!!!!!! Now I never it again, so applied power with multimeter on diode mode..................
**************************************************...
PPDCIN_G3H short to ground with magsafe, I have desoldering Q7080,D7005,(+U7000,D6950).
Pin 5.6.7.8 of Q7080 have Short to GND.
I have no idea why PPDCIN_G3H have short, I try to follow the pdf, inspected the board.....
I think that the short to gnd is beetween F6905 and Q7080(pin...
Hello , I have a problem with SMBUS_SMC_BSA_SDA have short to ground with magsafe connected.....
The macboook pro boot to OSX , but no detect battery.(battery is new).
I have low voltage (with magsafe only) on Pin 2 of R5280=0,60V to 0V, I decide to desoldering R5280.
R5280 & R5281 are Ok...
Fix Q7035(short to ground).
magsafe ok , green light ok, without battery, PPBUS_G3H short to GND.
I desoldering F7040 : PPBUS_G3H don't have short to GND.
R7140 Short to ground, PIN 2:
I have soldering new ISL6259, and in fact this the magsafe the problem, I have try with magsafe 85W and other 65W, and green light appear......(sorry for that)
I have replace F7040
Now I try to boot inside MBP, have green light No boot with battery(no battery indicator), no boot with magsafe...
