[Elecraft] K1 "88.8" on display

[jjbbl@bellsouth.net]

  Hi ya'll,
  I HAD a working K1 for over a year with no problems (S/N 679). It has all of the options. It is only a two band filter (20/17 & 40/15) board. I took it to work in a padded/foam Samsonite aluminum case to show it to the guys. I did not remove the cover or anything. When I got it back home and powered it up with the external power supply, all I have on the display is "88.8" and none of the function buttons work. There isn't any audio either.
  I haven't started troubleshooting yet, but just wondering if anyone might have seen this. I did suspect something got jarred loose. I removed the tuner and filter boards and re-installed them. Still nothing.I suspect a front panel/MCU problem.
