[TenTec] Jupiter Question

[Ed lawson]

Yesterday the Jupiter was working fine.  Today it started transmitting
as soon as turned on and generally erratic behavior, turned rig off, did
reset, this did not solve issues, turned rig off, turned rig on and
there is complete silence and rig is dead.  No lights, absolutely
nothing.  Fuse OK and power supply is providing 13.8 V to power cord.

Any suggestions of things to check before shipping off to be examined
by Ten-Tec?  Does this suggest a terminal problem?

Thank you.
