have you contacted flashforge ?

Also $200 seems ridiculously high, can i suggest a new it dept
In the meantime some glue and a printed chip cover might fix the issue.

Also check to see where the it dept are when the chip 'pops' out. Just a thought. $200 is enough to replace ALL the electronics in the entire machine, not just a single chip. Also if it pops out the odds are it'll pop straight back in.
Someone is taking you for a ride.
