Hi. The connector looks good.
Can you review the cable that is being inserted inside this connector ?
Are the keyboard cable contacts the proper pitch ?
What is the logic board 820-xxxx # that has this connector ?Last edited by mon2; 01-31-2022, 10:22 AM.Comment

Re: Macbook pro M1 A2338 820-02020 just 5Volts

Is it for the 820-02020 (A2338) or another ?Comment

Yopolean (Dynamite?) is a good vendor. Have bought from them before a number of times. They have this cable.
Here are other shops:

For the connector that is defective - is that on the KEYBOARD or logic board ?
If on the keyboard, then the keyboard should be replaced.Comment

on the Keyboard. Changing the keyboard isn't that great because of the rivets.Comment

Yup, been there and done that. Alternative is to locate a defective keyboard or source a new one to lift off this connector. It will be a bit difficult since these style of connectors warp (melt) very easily.
I would suggest a blad soldering tip + lots of flux and gently lift one pad off at a time till the connector is lifted. Hot air will warp / melt and kill the connector.Comment

If you see 5 volts, then the CD321xx ICs are not working.
Check the LDO rails on each controller first.Comment

Hi all,
I’m new to the forum and could use a bit of help. My name is Tom and I have a problem 😅
I bought a MacBook Pro M1 and also got a second one for spare parts. The seller told me it had a small water spill. After opening it, I found four spots with corrosion on the board.
One of those spots has damaged components — I’m not sure if they’re capacitors or other SMD parts. I’ve already cleaned the whole board with isopropanol, which made the other areas look fine. But could those damaged caps be the reason why the MacBook won’t power on?... -
Greetings to the entire forum, I ask you for help because I'm going crazy. A dear friend of mine gave me a macbook pro M1 A2338 that only works with an external screen. With the internal one, no backlight or image. Only the external display is detected from the system settings.
First I changed the display flat, then I made a backup with time machine and tried a reset in dfu but nothing to do, always the same problem.
I analyzed the logic board, it shows no sign of liquid or visible damage. I then moved on to examine the logic with the thermal camera and found that the UP701 chip was... -

Hi Everyone,
Please, I have a MacBook Pro A2338 M2, board number : 820-02773. The speakers and the microphone of the Mac are not working and I need assistance in fixing.
UR730 got damaged and short-circuited the motherboard. After removing the shortened IC; before and after putting the new one I ordered, the speakers [specifically the other one not affected by this IC] and the microphone are still not working. I do have sound through a Bluetooth speaker device or when I connect a headphone with microphone to the jack 3.5mm input. Also, media files do not play unless a... -
