U2710 getting hot, no shorts

본문:

We have a board that the U2710 gets really hot. I ordered replacement chips and swapped this power switch component.

Same situation stands, This chip really gets hot, the top half of the board doesn’t appear to heat up at all. VDD_Main draws 3.6V with a DCPS, PP1V8_SDRAM draws 0.450V. NAND lines draw nothing.

I suspect power is getting to this component but not getting through it possible?

Would really appreciate a second opinion on something a bit tricky like this. Thank you!
