I powered up my old TS-930 S yesterday and there was no RX. TX
operation appears to be normal. It seems that I have lost signal
somewhere between the front end and the detector. I suspect switching
or something in the RF section. I have no meter readings in receive.

For some reason the power supply and final fans are also not running.
I think that I remember that one of those fans would come on at power
up.

Any ideas?

Thanks.
