I'm still waiting that you activate my subscription, what's going on?

OK, now I have Green Led on Magsafe and only 12,56V on F7040! is it ok or must be have 12,6V only? The next problem I have, no Power on a UGATE2 (pin 26) of ISL6236 and no 1.103V out on (pin 16) Phase1 to PP1V1_S0GPU_REG.

I have resolder U7000 and now comes 12,27V on F7040. Have anyone idea?

Frankly, I do not I know it gave up just I also believe that the motherboard is totally shot.

My thanks to all who have helped here.:) OK, I have here the same motherboard with the same problem. SMC_BC_ACOK= 3,2V PP18V5_DCIN_CONN = 18,77V Voltage on pin 5 of U6915 = 18,77 Voltage on F7040 without battery = 4,582V Resistance of R5000 pin 2 = 3,59 KOhm to GND pin...

I think U7201 is bad, must be change. but I have to order

before was 12,6V and now 0,8V.

I have not change but only resolder U7201, because the machine doesn't start on.

I have nothing change in PPBUS_G3H. 0,8v is always present.

Did I understand this correctly. You mean this is normal with the 0, 8v?

PP3V42_G3H is present with 3,43V on pin 12 of U7000. did you mean that?

I have not ignored Duke. I had not correctly understood his question, because my English is not good. I have the most translation so I understand you can. I also have a business to run and am very busy. I understand that you have to do very much and respect that. I am concerned not $29. I...

Thank you, that here in the Forum will help one, the help comes unfortunately dicing. My last post was 5 hours ago.

3V on L7260 and 1.05 on L7770 is nothing only 0V! F7040 is 0,8V too. Few minutes ago there were still 12,6V. its sporadic, I don't no:( From U7000 on point 23 (Chgr_Phase) is only 0,8V. Why? is isl6258a broken

PPVIN_S5_P5VP3V3 on pin 1 of C4240 is only 0,8V. pin 16 (VIN) of U7201 is 0,8V too. I check PP3V42_G3H_PWRCTL and find pin 1 on R7802 is 0V. is it normal ?

Thank you very much for your patience. I change U5001 and now also the Green LED lights up but I still doesn't Start up. I take SMC_onoff too.

corrosion around is not there. It must be how much voltage?

I measure 3,416V

Sorry for my english, I didn't understand it. R5000 pin 2 = 5,75 KOhm to GND pin 1 = 5,14 KOhm to GND

I mean pin 1 and pin 2 of R5000 to GND!
