That's so dead that it seems to be more
than bad L401 or T401 soldering, not sure it would look that bad
with them not even fitted. It doesn't seem to be detecting any
signal at all. This might explain the problem with the RF scan, a
divide by a zero signal error.
I'd check everything on the top half of
the receive page of the schematic, ICs 402, 403, 495, 406 and 407
and everything round them.
If you have a scope check that the test
signal is coming into R518 and if possible follow it through the
receiver.

Tried that, no change. Below couple of screen shot, maybe they
tell you something? I have no idea?
Thanks Paul DJ0CU?
