well I can confirm this as I mistakenly plugged a 12v supply (which was supposed to power my ide to usb adaptor) into the H120 and the green light came on but wouldnt turn on.
I have taken it apart and found a brown scorch mark on the hard drive which sits directly above the LTNP chip.
Looking at the chip it is deffo fried
you can only see the top 5 "pegs" as the bottom of the chip is hidden by the hard drive support. and I think i need to desolder 4 fixing pegs to remove the hard drive support block
the first 3 pegs of the chip (looking left to right) seem ok and its the 4 and 5 pegs of the chip that look burnt and ther is a definate raised portion of the chip over these two pegs like a the blistering on paint you get when it is burnt.
I dont know if this is of any more help but Im wondering if i can get a replacement of this chip anywhere as Im willing to replace it
