Master Liu has a very good video but removing all layers is a pain. I would say i need 5-6 hours and also have a very high chance of breaking something.
Also most sources recommend to take a used screen because of missing calibration of new screens. But i'm Not sure If this also is the case for 2019 models.

MacBook Pro A2159 please help me to identify if this is a flexgate
Hi all,
i have a MacBook Pro 2019 A2159 which shows this screen when you boot it. I tried a SMC and PRAM reset without any changes. Everything in this book looks very clean even the board. The only "strange" thing i saw when it was open ist the fan which didn't spin at any time.
Any ideas where to search for faults?... -
A friend wanted the MacBook for some research work so for me it is done....Leave a comment:

Macbook A2141 820-01700 board is getting power but not starting. Dead SSD?
Hi all,
i have a Macbook 2019 pro which is not booting. Inspecting the board i had lots of dust and some corrosion in the U9080 area. I cleaned everything and looked for shorts and other visible problems.
I put everything back together and my USB tester showed 20v, 3.5a and 71w without booting or any fanspin. After several trys i was able to get into DFU mode but revive and repair both don't work and i get a error message (AMRestoreErrorDomain - 0x6 (6)
My thermal cam shows that ne NAND SSD on one side of the board have around 50c (the whole area here is heating up) and... -
Sonos Play 1 Gen. 2 with no power
Hi all,
i got a Sonos Play 1 Gen. 2 with no light and no power. Until now i only worked on Gen. 1 and know which components "like" to blow up but at this board everything looks fine. Until now i also didn't find any short.
The only problem i found was chip 6D9 heating up to 110c when power supply is connected. Since this is a PMIC i will replace it.
Do you have any other ideas what to check or can these chips get faulty without any other component quitting the job? -
Help to identify components / find schematics on a Flir Scout TKX board
Hi all,
i got a Flir scout where a connector was ripped off and i will have to make new pads. One big problem i have right now is that 2 small smd components are missing near the pads and i was only able to find a comparable pic of this part of the board.
So right now i need to know what i need exactly for a replacement and the values. I contacted Flir by mail but they don't give out schematics and told me that i can use the guarantee if i have it (funny guys).
Anybody has an idea what i can do? -
Hello,
i was able to fix the issue. The board was covered with some very fine dust and i gave it a good vacuum cleaning and finished with isopropanol. This dust was also inside most of the connectors.
After putting everything back together the macbook started normal and all colors look like they should. :-)Leave a comment:

MacBook Pro A1990 820-01041A strange / inverted colors and faded look on display
Hi all,
i got a A1990 which shows strange colors. Sometimes looking faded or like a water mark and only visible when the cursor moves over the spot. With an external display everything looks fine.
So is there anything i can do on my own to fix this issue?
It doesn't look like the flexgate macs i have seen.... -
MacBook Pro A2141 - is it possible to take preventive measures?
Hi all,
i recently got a Macbook Pro A2141 with a load of dust and hairs inside. After cleaning everything and checking the logicboard it looks fine and only needs a new battery and i will replace the thermal paste.
Since this model can have serious moisture problems is there anything i can do as a protection? Cover sensible parts with a layer etc.?
I was not sure if this thread is correct here but i don't have any acutal repair on this machine. -
Hello again,
im sitting at this board again and this should be the main problem. UF710 is looking the way shown in the pictures and RF713 is missing.
Right now i don`t have a donor board, so anything i can do without it? Only spare around is a A1466 board.Leave a comment:

So once again i'm looking at this board and i guess i made a mistake.
With power supply connected i get 0.070A and it goes up to 0.078 and back down and up. So is this already power cycling?
If so i also get different measurements when testing output of U8100 and U8100.
Diode mode:
PPVDD_PCPU_AWAKE 0,038v
PPVDD_ECPU_AWAKE 0,47v
PPVDD_CPU_SRAM_AWAKE 0,6v
PPVDD_SOC_S1 0,37
PPVDD_GPU_AWAKE 0,034v
PPVDD_DISP_S1 0,091v
PPVDD_DCS_S1 0,46v
PP1v4_LDO_PREREG 1,36v
Resistance is too low on all points. As example...Leave a comment:

I checked both sides and everything looks the same.
One thing i found is PP3v3_S2_UPC having 3,3v but in diode mode i get 1,6v without power supply attached.
Sorry if i get something wrong or it takes longer to understand but reading all this stuff not in my mother language is way harder than i thought....Leave a comment:

Thank you! So maybe another stupid question but can i find out which IC ist causing the problems or should both be replaced?
Im not at my desk so i don't know the name of the points i checked near the ICs but at both ICs i get 3,3 and 1,5v. If this isnt any help i will give more details later.Leave a comment:

[B]I2C_SMC_PWR_3V3_SCL[/B] is 3,261v
[B]2C_SMC_PWR_3V3_SDA[/B] is 3,260v
Checking CD3217 showed
PP5v_S2 on LC320is 0,006v
PP3v3_S2_UPC is 3,3v
PP1v25_S2 is 1,226v
All is present. So if i understand it right there can be a problem with UF400 and UF500?[B]I2C_SMC_PWR_3V3_SCL[/B] is 3,261v
