LG Top Load Washer - No Power Unit Dead

To the Dojo,

Washer WT7700HWA dead. I measured 120VAC from line filter to the PCB, and replaced the board. I thought I heard a pop.

Per this post, I checked and measured 120VAC from black to white on incoming power relays. I read .6-.7VDC at the UI connector, pins 1-4, 1-6, and 1-7.

Critical comments, snide remarks?

Thanks in advance,
