[ICOM] 706 receiver mute problem

Am trying out a nice 706MkIIG but a wierd receiver mute occurs after several
minutes.  The audio disappears, and the S meter bar graph slowly moves left
to zero.  I do have the faceplate attached to the main unit - it is not
separated.

The mike will not key - the receive light goes out - the radio is on but
inoperable.

The only way to restore it is to turn it off - pull the faceplate tab -
scoot the faceplate to the right for a second or two - slide it back to the
left to the locked position - and turn the unit back on - usually the audio
will be restored - radio now normal.

Bought a LDG AT-7000 tuner - hooked it up yesterday - seems to be working
fine.  Antenna is a G5RV with center up about 40' and ends drooping some -
output power on HI.

Did numerous total resets - thought it might be a squelch problem - set the
RF gain to no squelch - still same problem.

A friend with a 706MkII tried his faceplate - same receiver mute occurred.

Any ideas what to do or send it back to Icom?

TIA & 73
