A friend gave me a Macbook Pro A2338 for free that will not boot. So far far tried reseting the SMC controller, DFU mode and unplugging the battery. So far the easy fixes have not worked. From what I understand he used a 3rd party dock and apparently that is what he thinks killed it. I have done some basic repairs and soldering but on through hole components. Would like to narrow down what is causing ti to to boot so I can decide if it is something I can reapir or I can send it off for repair.

Hello out there.
I purchased this mac MacBook Pro 13'' M2 chip, model A2338, logic board number 820-02773 as partially working. Seller give me an apple report saying: "Liquid spill on trackpad flat, BMU battery flat and logic board. Macbook starts only when connected to DC IN and show intermittent shoutdown".
Now that I got it is does not start at all, Amp mether shows 5V 0A on both usb-c.
Tearing down the logic board I can confirm there was liquid spill on the battery connector area and the battery flat. Liquid spill also on the trackpad... -
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... -

Hey everyone,
Usually, I'm not the type to ask for help, but this time, I'm calling on your wisdom and expertise
I've seen what this community can do, so I'm pretty sure you guys can help me out.
Here's the deal: I noticed my MacBook got stuck in a boot loop. After opening it up and doing some initial troubleshooting, I found that the boot loop stops only when the trackpad is unplugged.
Now, just so you know, the trackpad actually works — I tested it with another motherboard and it's all good. Same for the cable, no issues there. The problem is only... -
I bought this laptop with water damage. There is corrosion on the logic board (ive included some pics). I removed the cr634 capacitor that was burnt on the ppbus line. The pad is still shorted to ground. I'm not sure how to proceed from here, any suggestions would be greatly appreciated.
The other areas ive included in the pics are the backlight circuit....
