    820-00165-A No fan spin

    I am using Amtech flux from Rossmann store so I reckon it's not crap flux :) and I cleaned the board twice in a ultrasonic cleaner so if crap was there it would be gone indeed.

    820-00165-A No fan spin

    Do you think it worth the try to heat more the PCH ? I don't want to destroy it, more of that it could be something else than the PCH that I have no find yet...

    820-00165-A No fan spin

    Hi, I've tried first to heat PCH without any changes, then replace R1301 with a 330k, still no fan spin (no I have PCH_INTRUDER_L = 2,5V)

    820-00165-A No fan spin

    PM_BATLOW_L = 3,3V PM_PWRBTN_L = 3,42V PM_RSMRST_L = 3,04V PM_DSW_PWRGD = 3,12V PCH_DSWVRMEN = 2,50V SMC_ONOFF_L = 3,4V I'm not sure about the 4 PCH's RTC signals you mean, but there is the following : PCH_INTRUDER_L = 1,66V PCH_INTVRMEN = 2,5V PCH_SRTCRST_L = 3,27V RTC_RESET_L = 3,27V

    820-00165-A No fan spin

    Hello, I have light on charger, but no fan spin. Historic : Macbook was find in a dump, no fan spin but after cleaning the backlight keyboard connector it worked fine. I ultrasonic the board even if it looked clean, but 2 months later I have this problem. PPBUS_G3H = 8,6V PPDCIN_G3H_ISOL =...

    820-00244 - A1534 2016 Running Slow

    Good call diag mode. I have 2 error codes, PFM006 related to the SMC and PPN001 related to the power management. I don't have any SMC for this board to try right now, but if there is crap under the SMC maybe a reballing would be enough. Before, do you have a good board like this to compare some...

    820-00244 - A1534 2016 Running Slow

    The only thing strange is the "Heatpipe outgoing Air" sensor, which is fun because there is no heatpipe on these...the temp is 128°C. Also it shows me 0.00V on something called "Mainboard S0 Rail", I don't think it makes sense, the Mac wouldn't run if it was the case.

    820-00244 - A1534 2016 Running Slow

    Hi ! I hate to work on this board, no fan spin = no fun. The board was liquid damaged, came here with no image. I refurbished the LCD connector that had minor corrosion and replaced the flex, LCD came back. When LCD went back, I discovered there was no KB no TP, the TP flex was damaged so I...

    820-3437-B PP3V3_S5 shorted

    Hi, so to let you know the end of this, I removed the CPU properly and the short is gone, so the problem was the CPU or the connexions to the CPU. I know it's a pain in the ass to reattach a CPU to a motherboard but I have time to spend on it and it worth the try as I have some junk 820-3437-B...

    820-3437-B PP3V3_S5 shorted

    haha exactly like a massage at a wood foot ! I'l try it and let you know at least if the short was coming from there. I would be very sad to remove the CPU and still have the short...

    820-3437-B PP3V3_S5 shorted

    Alright so your guess is reballing CPU ? Maybe dead CPU ? No way that I am doing a reballing CPU for a 3437-B, neither a CPU swap...

    820-3437-B PP3V3_S5 shorted

    Actually PP3V3_S5 is shorted but present, so could it heat with the MagSafe only ? I don't have any lab supply yet and I tried with the MagSafe and an IR camera, the only hot point is under PCH (or the other side of the board I don't know). CPU heatsink was already removed.

    820-3437-B PP3V3_S5 shorted

    I never plugged the board since I removed SMC and U7501. The short is 22ohms. When I lift L7560 the short is on PIN 2 and when U7501 lift up the short is only on PIN17, it looks like the short is on PP3V3_S5_REG_R. When I remove components I put them back in place after I checked the short still...

    820-3437-B PP3V3_S5 shorted

    Hello there ! I have a 3437-B from a MBA 2013. At the beginning I had no light on charger and no fan spin, no more historic. I found corrosion on PP3V42_G3H supply, I replaced the bad components and still no light on charger. I tried reflow SMC without success, and I finally had a light on...

    820-4924-A - Work fine but no image on LCD

    Every components are present. Diode mode on these caps gives me 0.267. Does someone have a good 820-4924 to confirm me these values ? Also, I measured EDP_BKLT_PSR_EN and EDP_PANEL_PWR_OR_PSR_EN on U8330, I have both 3.3V. I ordered a new assembly, I'll give you some news as soon as it arrive...

    820-4924-A - Work fine but no image on LCD

    Ok so it's a good news if 40V is normal, all my power rails seems to be fine on the LCD connector. I'll try an other assembly as soon as I find an other one. When you say "check all C832x", you mean check for a short on the pins or there is an other way to check a capacitor ? All traces between...
