Hey Carlsbad ... the box from Manley to Upscale must have taken a bit of a tumble as the tape was ripped across the top edge about 5 inches ( however the Manley box wasnt deformed...the outer box from upscale was fine..,
Upon detailed direction from EveAnna I recycled a specific connector, as well as checked all the others and the rest of the boards for cold joints etc...
I found the assembly quality first class...I suspect on these bayonet connectors the insertion force tolerances are a bit wide... the jolt broke connectivity and reseating the connector reestablished connection...
I have seen it even on the MilSpec stuff I worked on... mechanical insertion force and wipe are rare but do occur
