[Icom] IC-706mkII Problem

[William J. Wickstrom]

Hello All:
            I just love my �mkII, but it just today developed it�s first
(ever!) problem, and it�s got me scratching my head:
I was in the middle of a QSO (mobile) with a friend on a local two-meter
repeater, and when I unkeyed the mic, I noticed the radio had gone dead (no
display, lights, audio). Checked the power connections and fuses, and all
was right there�but then I noticed that the radio now emits a mechanical
clicking from an internal relay, cycling at about 2hz whenever the rig is
connected to power. The power switch has no effect, nor does powering the
rig from my shack supply (which is currently running the �ProII just fine).
Just the same relay clicking.
            I have removed and reseated all connections to the radio,
including the front control head to the radio�no change. I don�t have a
service manual (yet) and, short of just tearing into it blind or sending it
off to somewhere (probably Malcom), I�m at a loss. Any ideas? Anything I
might have missed?
