http://www.users.on.net/~fzabkar/ssd_flash_ics.txtCan you not tilt it and read the markings? What are the voltages on the pins?

thanks for the link to the other post, sad there was no final answer from OP.
there's several component to gnd here (both pads), all in red. I was thinking the Cap in blue could be the root but DC-DC is clearly heating quickly.

It's easy enough to pull the ic and see if the shorts disappear.
