Chosen Solution
Dear ifixit Community! I have a problem with my MB Pro 2017. After switching on, everything works normally in principle. But after a certain time the MB freezes completely and then it crashes. As an error message I get kernelpanics displayed (see pictures). I have now taken out the logicboard to check it for abnormalities. In fact I noticed a burned out resistor. This resistor is called R1802 and according to my research it is connected to the CPU. Do you think this resistor is causing the problems/kernel panics? Many thanks in advance! Greetings Phillip Logicboard number: 820-00840-a (Sorry that some of the bug reports are not fully visible, but I wanted to quickly photograph it before the MB crashes again) Edit: I have now attached pictures of some of the components connected to R1802. I can’t see any visible damage as with R1802. Edit2: The MacBook does not have water damage according to the previous owner. The logicboard also looks very clean, so there is no corrosion to be seen. The previous owner said that the Macbook became extremely slow after the update to Monterey and at some point these crashes and errors came. But I can’t say if it was really like that….
R1450
U5000
C1804+J1800
Is there any liquid damage on the computer? R1802 Isn’t directly connected to the CPU its connected directly to the SMC U5000 and also J1800 and is for the power button so i suspect the problem came from those areas or liquid damage on the keyboard near the power button. Replace R1802 and check both ends with a multimeter in diode mode. I will attach a picture with the normal diode mode readings on a working board.
Sorry for not responding sooner, Sadly you do appear to have a short as both the first and second images are overheated traces on the logic board. Clearly a large current traveled along the the traces where they have blistered up. So while you have at least one burnt component something deeper happened here. The traces will need to be checked and new lines patched in hopedfully you don’t have shorting across the traces or layers.
