Mine failed immediately after apply power to the board after wiring up the power connector. Nothing else was connected. There was a loud crack, and a puff of magic smoke, then silence.
Photos of failed chip look similar.
I think the chip may have been already replaced once on the board before I got it - see the soldering of the chip pins vs. the soldering ot the other surrounding connections. Looks like it was manually soldered to me. These photos were taken before I replaced the bad chip with a socket, but after the failure happen.
Probably one or more bad chips involved, the replacement in the socket has been completely well behaved.
