[Yaesu] FT-990 Back on Line

Just got the rig back from Yaesu Service in Cerritos.. lousy traffic, but
what the heck. I had many responses to my post a couple of weeks ago and I
committed to reporting back once thing were resolved. The symptoms as you
may or may not remember were a loss of all functions excepting only the
illuminating circuit for the meter.
OK .. to summarize:
I was unable to speak with the tech that did the work but one of the guys
on the desk interpreted his notes as follows:
The CPU had shut down. It might or might not have responded to a "hard
reset" as described on Pg 5 of the operators manual. I missed that one! I
tried the reset from the front panel, but not the one accomplished by
disconnecting the rig from it's power source and turning off the "Back Up"
switch for a couple of minutes. This switch is accessible from the opening
on the top panel. It may not have worked anyway according to the tech.
They found a fried 5V regulator on their initial visual inspection. How
that regulator does or does not relate to the CPU function is uncertain.
Could have been just a random spike or a static discharge. Main lesson
learned .. don't forget to try the "hard reset"
So what I ended with was 1-1/2 hours labor -$75
Parts - $3.79 ( Regulator and a new lithium B/U battery).
And.. 10 days worth of withdrawal pains
Again.. thanks to all who responded.
But obviously I will not forget to try it, if this ever occurs again.
