    Sir Kim . . . . I've now got us started up. . .GOOOOD . . .in the interim, take that PC board out in bright sunlighting and using a magnifying glass, check for what I think might be some component leads that are "floating" within their solder blobs. DO inspect them vewy-VEWY cawefuwwy . . . a...
