There is no separate FX circuit board inside. And no plug in chips
on the board. Everything is soldered on one single board. There is
nothing and bench technician can do to fix the problem


Baloney!

Competent bench technicians can repair solder joints, and replace bad
components soldered to printed circuit boards.

If the problem is diagnosed as a RoHS compliant (e.g. brittle) solder
joint, it may be easy for a competent technician to fix.

If the problem is diagnosed as a bad resistor, it may be easy for a
competent technician to fix.
