Identifying Caps - Any help appreciated :-)
Hello lovely iFixit Users and mods,
I was trying to fix my aunts Macbook as her little son spilled a little bit water over it. As I always wanted to fix a water damaged macbook once in my life I thought I give it a try. I bought an ultrasonic device and the right cleaning solution and cleaned it with it.
Now I inspected the board visually after all the white blueish things went away and saw that a few caps have no silver solder on their ends, instead you can see the ceramic part of the caps exposed. I want to change these but I am not sure how to find out which ones would suite it? Could anyone identify these?
I also need the same ones on the backside of the logic board (they look the same 100%).
Thank you all for your contribution :-)
@reecee thanks again for your input on this. I will check the caps once my new multimeter will arrive. I will also try your tip with the detached keyboard etc. (I checked the keyboard, trackpad etc on another machine tho and all these parts seemed to work fine).
I also took picture of the logic board before I began to clean it. Here are they
Might help with understanding the current state more. This is the only area that was affected by the liquid spill as far as I could see as the water indicator on the other side was white but these two on the charging port side where marked red and that region had that blueish white stuff around the smd parts too.
I took pics of different angles too so if you need a specific area, name or mark it and I try to find out if I have pictures of it.
Thanks again for the help!
@oldturkey03 Sorry for the late reply, I somehow missed your comment. Yes here is a picture of these caps I am talking about (I only took a picture of one side but the other side looks the same with the same problem).
Upon further inspection I found this cap that is missing it's silver contact pad too (the cap in the red circle)
And these Inductors (i think these are inductors, sorry if i am wrong here) don't seem to be happy as well

The two chips mentioned by @reecee appear to have corrosion under them which can clearly be seen in this picture bellow:
The two chips up close
According to iFixit these are 2x Texas Instruments CD3215B03 66AQ8YW G1 that are nowhere available?
So a reflow with some flux should maybe remove the corrosion under these chips I guess?
Bu iyi bir soru mu?
