.... Finally I was able to locate failed diodes on the bottom side of the upper board. Before I go purchasing diodes. Any suggestion on the rating of the diodes and what would cause them to fail? 2 boards same exact issue.

Can you mark in the photos exactly WHICH diodes failed (or did I miss it)?

And did they fail open or closed? Note that if a power supply circuit, it's highly likely some of them are Schottky type.
