Client came in with a 820-00165 acting up, keyboard only types in caps and other random stuff. So suspected liquid damage. Saw some corrosion on the board and coffee on the keyboard. Boards was working, changed some bad IC, ofcourse after I did, it stopped :P. Now fan spins, stops, starts to...

Yes I will also see if I can get parts for it, might be a good add on to the Mac biz, if Apple makes it less repairable and Microsoft will go the opposite way it can make up some lost business.

At the moment we only repair Macs. With the new Surface 3 coming up, that actually can be opened easily, would anyone consider repairing these as well? Would it be possible to find parts for it? Anyone with experience repairing the unrepairable models that came before this new one?

Hello, we have a 00165 that was badly liquid damaged. Repaired all and now everything works accept for USB J4600, it has power but no data. W checked all lines no short, All resistor measure OK and SMC area looks clean.Main spil was around U7100. How to check the data lines of this port?

How do you find a short in PPBUS if the board is clean without putting power in it? I put 3v in a 13v line.

So i got all accept CPU Vcore and CPU gets warm = RIP? PPBUS_G3H = 13.04v PPBUS_HS_CPU = 13.04 PP3V3_G3H = 3.4v PP3V0_G3H = 2.99v PP5V_S5 = 5.1v PP5V_S4 = 5.1v PP5V_S0 = 5.1 PP3V3_S5 = 3.3v PP3V3_SUS = 3.3v PP3V3_S4 = 3.3v PP3V3_S0 = 3.3v PPVCC_S0_CPU = 0v PPVCCIO_S0_CPU = 0.98v...

OK some update, I think it was not completely dry yet after ultrasonic as I left it overnight and now I get 20v, but only 0.52amps. Will check more voltages and report back later.

Attached image from D3302 some solder:oballs popping out might be a clue, but no short on PP20V. I have 3.3v and 4.7-4.8 on 5v.

Hello, this board did not turn on. I got 19v and 0 amp. FOund a short in PPBUS, smoke out of U7960 when put power in it. I replaced U7960, short is gone. Now when I connect power I dont get 19v anymore only 5v, I do have 13v on PPBUS now..... :rolleyes:. Since 19v showed up before I assumed...

Hi Guys, I have a 00926 that 2-5 x a day suddenly reboots. First will try a clean installation and see what happens. My question is are there know issues with this board like with the 2013/14 15 inch models?

Hi guys, a weird one here:p. Customer came in with dead macbook, replaced the battery, macbook runs. 2 days later client returns, dead again. I disassemble, test board with a good charger, fanspin.... Must be a badly connected keyboard cable? Put it back together, rebooetd about 20 times in a...

I have a client in Thailand where I replaced the SMC, only had 1 hour time as he is flying back to Italy next day. Mac was working after SMC replacement but stopped few hours later so it has to be done again. Since I have no time to fix it I gave him a credit, if there is anyone who can replace...

Ok there was indeed a corroded trace near U6100, after fixing the line and give it a good cleaning, working again :)

Got this liquid damaged 820-3435, liquid around U6100 and u7600. CLeaned it up a bit looks pretty decent. Now it doesnt turn on but I have a pulse on L7520 and Enable on pin 4 of U7501, but missong 5V, 3.3 is present. Does that mean U6100 is working as I get the 5V signal and I have to look for...

nothing on PM_SLP_S5_L , PMU_ONOFF_L = 3.38v

https://drive.google.com/open?id=1g8...omqvrV5nH26zBB Edit: i just got the correct schematics, uploaded it.

I have the boardview for 01041 but the schematics that came with it only had 3 pages :(. Anyway, I checked for enable signal P5VG3S_EN and its 3.3, so i tried to replace U7650, now i get 1v at P5VG3S_VFB1, no short, assuming thats the outgoing 5v signal since i dont have schematics. I will...

I checked all the power lines and I am missing PP5V_S4, so I will get started from there. Here are all the readings, 12.63 on PPBUS seems too low? Charge = 20v 0.08A PPBUS_G3H = 12.63 PP3V3_G3H = 3.39 PP3V0_G3H = 3v PP5V_S5 = 5.13v PP5V_S4 = 0v

I get nothing when turning on on these pins. Could be a CPU issue? I also read somewhere that flashing the rom fixed the issue?

I finally got the boardview and schematics for this board so back at it. Now when I connect the charger, I get 20v and 0.9A. Does this mean the charge circuit works but its not booting?
