Will replacing the logic board alone help cure liquid damaged parts?

Hi! Before you go to the expense of a logic board, definitely try replacement RAM. Often the memory itself gets water damaged, and simply replacing it brings the computer back to life. I've had many a water damaged MacBook sold to me for $100, only to find that replacing the RAM brought it back to life. That's not always the case, of course, but it happens enough that testing the memory is just about the first thing I do when faced with a "dead" MacBook. Try a single module of known-good RAM, and try it first in one slot with the second slot empty, and then if that doesn't work, try the reverse...this technique lets you know if one or the other slot is damaged.

well, there is no guarantee that replacing the mainboard will fix the machine.

As the board is most likely stuffed, I would wash it down (water and a toothbrush) to remove any residue.

As for the machine at present - what does it do - did you try to swith it on?

Here's some things you could try before replacing the logic board.

Good Luck,

Was 11Team serious! water and a toothbrush? jesus i hope you didnt do that! lol, you should have put an electrical spray cleaner on the board which you then clean and on its own its removes any and all spillage from electrical equipment, when i get spillage the first thing i dont do is try and switch it on, i clean all components then leave it over night and sometimes that does is and i dont need to replace a single part! but thats not all the time, only once have i had to replace the logic board.

hope you got it working

Liquid damage can wreak havoc on internal components, and determining the extent of the damage is crucial. While replacing the logic board may address some issues caused by liquid damage, it's essential to assess all affected parts thoroughly. Additionally, professional diagnosis and repair may be necessary to ensure that all damaged components are properly addressed, potentially saving the device from further harm. Understanding the limitations and complexities involved in repairing liquid-damaged electronics can guide users in making informed decisions about the best course of action. Overall, this discussion likely offers valuable insights into navigating the challenges of liquid damage repair in electronic devices.
