Hi, I found this video because I bought a 60CSX with the same exact issue, except it looks like it's much more manageable (def not as corroded) with an intact microSD reader. If the process of cleaning does not work completely, what tools / resources would you recommend I get to fix it? You hinted at the end of a microSD card replacement, which would probably require a hot air gun, right? Also, what is the specific point of failure in power delivery?
