no other rails pulsing

Real good know 85W charger, PP3V3_S5 pulsing

Sorry PPBUS is 12.60V already check resistance between pins 17/18, 27/28

green light and orange present, no power on from battery and charger ppbus_g3h 16.60v pp3v42_g3h 3.42v smc_reset_l 3,42v smc_on_off 3,42v smc_bc_acok 3.31v good charger and battery know,

find burned pcb under J3500 may be cut pcb

how to do :/

Good magsafe board and charger 85W guenine know PPDCIN_G3H 16.8V PP3V42_G3H 0V (resistance line to GND 284 ohms) PPBUS_G3H 0.710V Already checked 17/18 27/28 of U7000

Bass speaker connected ?

This bord work now thanks solved i Will bought 85w

60w i put to trash all my 60w magsafe 2 (buy on ebay seem guenine apple logo but pretty sure this fucking fake charger chinese (exactly same design of genuine). I bought charger from apple store everything work perfectly I can't remember Sticky "stop using bullshit charger" not present on the...

Board power on :) battery only chime and display ok batterie charge replace isl and checked resistance area 17/18 3.4ohms and 27/28 20.1ohms and R7125 ok tried another charger good same problem no startup from charger tried short smc_onoff_l work on battery only

It seems to me i was not sure, ok i’ve understand Thanks

Thanks anyway, just a question not link with board. Why cpu vcore never shorted I see many post you said not possible cpu vcore shorted have you explanation if not long please

resistance to gnd 126.7 ohms on L7630

PP1V05_S0 2.7mV PP1V5_S0 0V PP3V3_S0 0.183V PP5V_S0 0v PP5V_S0_FET 0.6mV PP3V3_S0 0.182V no pulse no cycle :/ I do not know if it's normal to L7630, continuity 1 beep / second and stop one beep and stop loop, (without chargeur plugged of course)

Yes i will Check power cycling want say voltage pulse ?

Okay that's what i thought :(, thanks anyway

Yes présent smc identical donor 820-3476-a

Ppvrtc_g3h 3.3v

inject 3V, current 0.24a find smc hot replaced now i've green light / orange light and no fan spin not power on PP3V42_G3H 3.42V and PPBUS_G3H 12.61v SMC_BC_ACOK 3.39V SMC_RESET_L 3.39V PP3V3_SUS 3.34V Already checked resistance SPI Bus Series Termination, next step diodmode without U6100 ?
