Hi guys. I have this A1708 with a backlight issue. There was corrosion damage on U8400 and surrounding it. I replaced U8400, C8471(shorted), and C8441 and all resistors are fine. I was getting on PPVOUT_S0_LCDBKLT 12v, but then I changed also D8410 and Q8410, just in case. I measured of course...

Hi. I have this A1990 with the battery not being recognized properly. SMBUS_3V3_BATT_SCL is 1.2v, and all others are fine around Q6950. I also have PP1V8_SLPS2R. I replaced Q6950 and U6950 to make sure nothing was going on there, and I resoldered the battery board connector to make sure all...

Hi guys. I have this board with no power stuck at 5v 0.55amps and small fluctuations on the side of the amps. On the thermal camera, U5200 pulses. No short on U5200 and surrounding components, no liquid spill, and no voltages going to the PMU U8100. Would appreciate your help on this. Thanks

Hi, repair people :) I have this A1708 MB that had no power. There were shorted caps C6425 and C6405, both CD type C controllers, and a P13USB32 chip(not on schematics or BW). After all that I plugged in and got 20v, it stays around 0.046 and then goes to 0.056. All Ics are taken from another...

Hi. I have this M1 A2337 board that powers on normally and I have a backlight and no image. I measured all voltages and diode mode readings on the LCD connector and all seem fine. The board doesn't show anything burned, and no liquid damage. I tried 2 other LCDs but still just backlight no...

Hi. I have this A1708 no power draws 5v 0.020-0.030 range. This one I fixed 2 years ago and replaced U2800 and also one of the type c controllers. This time I re-balled U2800, and didn't work so I changed it from another board, and still the same. No short circuit on the board.

I have this A2338 it was liquid damage in multiple places on the board. I removed the corrosion, resoldered all broken connections, and rewired some. The laptop is powered on but the backlight comes on for only 1sec and turns off, and still running and boots up on external. I replaced UP800...

Hi. I have this board with no backlight and no image, but powers on and works on external without any issues. I have voltage on Q8400 pins 3 and 4 and no short circuit anywhere, but I'm missing EDP_BKLT_EN on pin 1 on R8442. CPU not sending signal?

Hi guys. I have this A2289 with no power on state. The adapter is stuck at 5v 0.2-0.3a cycling. There was a bit of corrosion on D8450 pin 1 and C8495 pin 1(no stuff), which I cleaned and resoldered, and still no power. I checked the diode mode for all coils and with no issues all values are...

Hi. I have this A2141 with a shorted SSD, and I found and replaced the SSD, only one of the chips was damaged, all else on the board is fine. Now I'm trying to restore it with DFU mode with another Mac (Apple Configurator 2), but I get an error. I'm not sure if the error is from the chip not...

HI. I have this A1398 820-00163 board that once in a while shows a picture, but mostly doesn't. I'm suspecting the GPU, as I had before the 820-3332 and after disabling the GPU all works fine. Is there a way to disable the GPU on this board model, please? Thanks :)

Hi. I have this board 820-3115 with no power and no green light I have measured no shorts, and the voltage reached Q7085 pin1,2,3. I have replaced U7000 and now I get the green light and only one time the fan span and it now stays on a green light, but I can see it it's blinking a bit...

Hi guys. I have this Macbook 820-3332 MB with an issue with not showing a picture every time, and it usually happens when the battery is plugged in. There was some corrosion on C4905 together with R5076 and R5075, but I took care of that and also on the R3655 area but all resoldered. Once I...

Hi guys. I have this A1932 Mac and it's no power. I get 20v when and the amps go to 0.099 go back down to 0 ans stays like that. I noticed once it went to 0.300 and that was it. No short circuits or components found and no liquid damage, no burned parts and the laptop it's in perfect...

Hi guys. I have this A1707 with no power stuck at 20V 0amps. No liquid damage. The ISL9239(U7000) was heating up a bit and I replaced it, one contact under it was gone, Pin 36 TBA_GATE_Q1. Also, I have replaced U3200 cause it was heating up. Now I have the same state no power 20v. I noticed...

Hi guys. I have this A1707 powering on and I get only backlight. No liquid, no burned parts, and no shorted lines on the LCD circuit. I noticed on the EDP_INT lines I have only 0.4v, how much it should have? I haven't tried another LCD, waiting for new stock of those models lcd. I have...

Hi guys. I have this A1502 with no power. I have all power lines present, U1900 I replaced them just in case, PM_SLP_S4_L is present, no short anywhere. I had the camera chip U3900 heating up near contacts 14 and 29 and I removed it not heating up anymore. Now when I plug it in, as before...

Hi. I have this board 820-00928 it was not powering on, and it was full of dust. I did the cleaning and at first, it didn't turn on, but then it started. I did the usual check on all power lines and on a few, the diode mode measurements are lower, but it still powers on. I found on QB701 Pin 1...

Hi. I have this A1398 with no backlight issue. The initial problem was Q7706, I replaced it and got all voltages but no backlight I had output on PPVOUT_S0_LCDBKLT. the output voltages are coming and going as they like :) SCL and SDA lines are almost 5v and diode mode is good on all components...

Hi. I have this A1466 with PP5V_S4RS3 missing and also PM_SLP_S4_L missing. I have PM_SLP_SUS_L(3.3v) and PP5V_S5 5v present. I tried reflow on SMC, I replaced U7501 with no changes... No short lines all diode modes are good. I found that when plugged in only U7100 warms up to 30 degrees and...
