Hi there,
Yea, That’s a NO-Go 
on the QC for that piece , wow. 
Looking at the schematic there are 9 pins that must be soldered. The others should as well if nothing else for stability.
I would solder them all (generous with the flux ), then clean it with some alcohol.
Probably work right away.
The pins I would be less concerned about as long as they connect and it’s not a “Crunchy”
connection.
