Update on Not-starting...
Master Reset did not fix the problem.
Removing both USB and LAN cables did not fix the problem.
Reload FW - will not allow a reload of the current FW. Will not allow a roll-back to an earlier release.
Work around:
Leave the radio in the factory default "Instant On" mode. Although I rather have my radio OFF when I turn it OFF but if Kenwood has the partial OFF as default I guess I don't have a problem with that.
I will be poking around a bit more as I think of alternatives. But it is such a time sync to have to wait so long before the radio will come on.
A phone call to Kenwood is probably in order now too.
I have a lot of hours on this radio since March 2013.

Avril 2018 - Code erreur ERR-005C / Abnormal Transmit Signal Detection
I worked many years with my TS-990 without any problems.
Last week I got several times Error 005C → .
The error goes away when shut down the radio and turn it on again.
But after few qso’s the error keeps comming up.

The manual says to do a full factory reset, witch I done.
At first sight it seems that did the trick but some hours later the error pops up again.
I did not do any software updates lately.

I had the problem for several months , finally sent it to Kenwood uk.
It took them some time to find the fault .this is their report-System eventually verified.
Then failed permanently. Replaced Q7 (a2) & Q7 (b2) Pair on Final unit.
Before it finally failed they were shorting.
Unfortunately expensive repair, have had the rig back a month used every day no sign of the fault.

I replaced the potentiometer with the control of the driver's quiescent current and the power stage,
and then adjusted the quiescent current of both stages according to the manual service.
