[ICOM] Icom IC-706MkIIG Possible Master Oscillator Problem?

[Rick Robinson]

Tighten the circuit board mounting screws. Also check the ribbon cables 
to make sure they are seated squarely and completely in the sockets. 
These are the most common service return problems and the cures.Next do 
a full cpu reset. GL, Rick.
