Wes:

Based on your findings, i.e. tuner didn't work,  and then it did work, 
then it stopped working, does indicate to me a faulty connection as 
opposed to a faulty component.    I keep saying this as I've experienced 
it many times both with ham equipment and professional equipment.   Fact 
is,  connectors which stay in place for a long period of time will 
oxidize.  In many instances, simply unplugging the re-plugging the 
connector provides the wiping action adequate to allow signals to 
pass.    Sometimes just moving the cables around will wiggle the 
connector enough to all penetration through the oxidation and restore 
operation.......for a little while.    Hence, my suggestion for cases 
just such as you describe would be to "clean connectors".

Again, I offer my suggestion.   Using a contact cleaner of your choice, 
I like Cramolin or Pro Gold, apply a small amount to a Q-Tip swab and 
scrub the male pins of each connector.  Then plug it into the female 
connector, unplug it and re-plug it a couple of times.  This allows the 
contact cleaner to wipe onto the female pins.   Usually this takes care 
of many intermittent and ill defined issues.   Doesn't always cure the 
patient, but in many time, it does.   Never spray contact cleaner into 
the radio as one has no real control as to where it might end up.  More 
is never better in this case.
