    SSD Samsung PM991a fail

    Hi everyone, I have this ssd nvme that has suddenly stop to works. It was in a laptop. I unplug it from the laptop and connected via usb adapter to another PC. The drive is not detect, nothing. I tried with Win10 and Lubuntu but same.
    Then I grab my thermal camera and noticed the top side of the nand chip went hot immediatly, raising the temp from 50 to 85 deg in a minute. I inspect the board and take some resistance measurments to ground but no short detected. I suppose the nand is shorted internally. Can you help me diagnose this drive and eventually fix it?
    I can take also voltage measurments but I don't know what should I aspect.
    Thanks you all
