    MSI GP62M 7RDX nickel of PCH broken and 3v shorted

    Hello, I have a MSI GP62M 7RDX, MB : MS-16J91 rev 1
    Schematic posted in this page : https://www.badcaps.net/forum/showthread.php?t=84710

    I saw that the PCH is broken, and it has a brown stain (gone after scratching and no trace on copper).

    Do you know if cracked nickel on PCH means it is dead please ? I found another issue ; 3v line shorted and that could explain why the laptop don't start (no light, no led, nothing after pressing power button). And I don't saw anything shorted around PCH, but I don't know how to check it.

              Hello:

              I have both these laptops that appeared to have the same fault so I thought I would have a go at replacing the PCH as something to learn, they both are using the same PCH.


              I started on the ACER:

              Up on connecting power no signs of life but current is consumed from the bench power supply and the PCH is hot.
              All the caps on the top of the PCH are showing 0 ohms and the 3.3v rail is shorted.

              I followed the videos from Sorin, Electronics Repair School on Youtube heating from the bottom to install. I practised on around 10 scrap...
