I think this is just one of many 'board' problems that occur with Kenwood
gear. I would open the thing up and check (ie. remove and replace) all the
on-baord connectors. I have seen problems like this caused by the break-down
of the potting compound used in the RF/PLL side too (albeit in a TS940).

Subject: [CQ-Contest] TS-950SD Rvcr Problems
I'm having trouble with my TS-950SD. Every so often, the receiver goes
dead. The S-meter goes full scale and I can't hear anything. It's as if
the RF-gain was turned all the way back.
Most of the time it will correct itself within a second or two. Sometimes
cycling the power on an off will correct it, other times I have to leave
the power off for a while. It's hit and miss. Sometimes it happens
shortly after I turn on the rig, other times it starts happening after the
rig has been on for a few hours. Sometimes the receiver will go quiet (and
full S-meter) for a long time (minutes), other times it will quickly cycle
between working and not working, as if someone was playing with the RF-gain
knob. I've reset the microprocessor, but it's still the same.
Has anyone experienced this before (not necessarily with a TS-950)? What
was the root cause?
