Hello. Need a fresh look. MacBook shows no signs of life.
When connected to USB-C with the battery connected, the consumption is 20V/0.220A and PPBUSG3H=11V.
If you disconnect the battery, the consumption will be 5V/0.220A and PPBUSG3H=12.3V
PP3V3_G3H=3.3V
PP5V_G3S=0V
PP1V8_SLPS2R =1.8v =0v=1.8v =... cyclically
voltage around u7800 appears/disappears cyclically.

If anyone is suddenly interested in how I got rid of the horizontal lines on this display and what happened to it, you can watch it on my YouTube channel. [url]https://youtu.be/4L6XiIRbgfs[/url]https://If anyone is suddenly intere...XiIRbgfs[/url]...Leave a comment:

Macbook Pro A2485 820-02100 SSD
Hello. SSD UN0000/0100/0200/0300 were shorted in the MacBook. There are 4 SSD chips on the board. I don’t have the same board and I removed two SSD UN0000/0100 chips from the MacBook on the M1 A2338. I installed only these two, but the machine does not recover and gives error 28. I have a question: is it necessary to have all 4 or should it work with two chips? Is this important for the M1 Max processor?...

This is only a replacement of the LCD. Even replacing the T-con with cables did not change the situation....Leave a comment:

R6907 was only a few miliohms instead of ohms. Replacing it resulted in charging the battery. As always, many thanks to [URL="https://www.badcaps.net/member/295753-mon2"]Mon2[/URL] for the directions on the search path. Everything worked out, thank you very much

Macbook A1707 820-00928 battery replacement
brought in a working MacBook for battery replacement (swelled up). After replacing the battery it stopped turning on. tried connecting the old battery without changes. consumption with the battery connected and without the battery is the same 5v\0.200a on all 4 ports. replacing 9239 did not help -
no camera is not detected. I put the board in a known working case with a 100% working camera, but the board simply does not see the camera. At the same time, the light sensor, which is on the camera module, works properly. I will note that there is not even an attempt to connect to the camera. That is, there is no green light blinking. It is as if the camera simply does not exist. I think that you need to try replacing the T2...Leave a comment:

I have seen several threads with this problem on boards.rossmanngroup.com and as I understand their repairs were not successful!

Thank you for the link. Unfortunately, the person never answered whether he managed to fix it. Restoring via DFU did not help me. Neither did replacing U8502. Any other thoughts on what could be wrong?...Leave a comment:

I installed the board in another case but the problem remained. I suspect that the problem is somewhere in the smc. The board is in perfect condition, there are no signs of moisture....Leave a comment:

MACBOOK A2159 820-01598 FAN SPEED
Hello everyone. It works very slowly and the fan spins very fast. The touchpad was flooded. I replaced it but the MacBook is still very slow and the fan spins at high speed. Resetting and bypassing SMС does not help! Please tell me what to look for. -
macbook a1989 820-00850 no camera
Hello friends. There is a problem, the camera does not work. Replacing the display did not bring results. The problem is on the board. Please tell me where to look?
