Plus one on the TMP connectors. It has happened to me a couple of
times over the years. A little dab of Deoxit and move it around a bit
when re-installing seems to do the trick.

Pete,
There was a similar report on the forum last year from Per-Tore, LA7NO. In
an extended email conversation we deduced his problems were caused by failed
PIN diodes in one of the T/R switches, which ultimately proved to be the
case. His K3 also lost TX power, unlike your situation, so you may have
lost only the PIN diode in the RX path. There were many other possible
causes suggested by others on the forum around that time (late July 2020) -
you might read that thread and try the simple fixes first (e.g., twist and
re-seat the TMP connectors) before delving into circuit/component failure
possibilities. The old thread is here:
