Currently Im trying to get this A2338 13" 2022 MacBook Pro M2 to function properly, Right now the trackpad and keyboard are not working but the power button and keyboard backlight are working. the Touch Bar shows display but does not respond to touch. I bought it on eBay and it was described as having a bad lcd. When I received it however I found that it was also missing the wifi and bluetooth antenna along with most of the screws hardware. it was also showing picture on the LCD but no backlight, I could also see some lines on the screen indicating the lcd was also somewhat damaged. on top of that it would only stay on for a few minutes before rebooting itself. So using a donor m1 a2338 that is activation locked, I replaced the wifi antenna and hardware, then I bought an m2 a2338 shell the had everything (the battery, screen, keyboard) but the logic board. I put the logic board from the m2 in there and now the touchpad and keyboard and Touch Bar do not work and the screen only shows picture on boot up (still no backlight) I confirmed the screens and their backlight work by connecting them to the m1 that I have. Im kinda lost on what do do or where to go next. the laptop still works but it needs an external monitor/ keyboard/ mouse to function. Im currently using it to write this post. Should I move them back to the original body? Or is it going to need a system configuration from apple to ever work again? I used apples repair Manuel as a a general guideline for the replacement procedure as well as a few videos to minimize the risk of me breaking something. I just got the schematics for this device and the free board view software, but it's my first time using schematics so Im still learning how to read it. Any help would be greatly appreciated. Thank you.

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... -
