It’s a long shot, but we have managed to keep our flaky two-channel VFS
alive for quite a few years by boosting the level of the output of the comb
generator (we used a TI TRF37D73 broadband amplifier module module).
It’s frustrating to know that schematics must be out there somewhere!
Best wishes

Thank you all for the replies,
I forgot to mention that this is a 4-channel VFS module and both channel 3 \
and 4 are also bad. Only channel 2 still works for now. So it seems the other
three channels share some kind of control or gating system?
I probably shouldn't use the term "easy fix". What I meant is if there is any
way we can diagnose the component inside the module to find out which one(s)
goes wrong and possibly replace it in-house.
Since John mentioned that there is no schematics, guess it is almost impossible.....
