KX3 will not power up

[Tim Seed]

Dear Elecraft brain trust,
                                                        My KX3 seems to have an issue. It will not "boot up". The power on key combination, on the second quick attempt gets the back-lights to power on, initially at a dim value, which then drops to a very-dim setting. It was working fine 3 weeks ago, when I was working /P.

        This problem manifests itself with the Batteries installed and the DC Power connected. It is exactly the same in both cases.


        So far I have checked
                        - Input Power. Centre positive. Voltage 14v
                        - Internal Connection cable
                                  Appears well seated.
                        - Batteries.
                                  Removed them all. Same result
                                  Externally charged - then replaced in radio. Same result.
                        - Soft buttons on radio
                                Non appear depressed
                        -Dials on radio
                                All rotate/Depress where applicable. no obvious damage.
                        - No Usb Connection possible as the radio does not power up
                        - EE-INIT also seemingly not possible

        Next steps / What have I missed ?? Or is it time for Tech-Support ??

        Many thanks

                        Tim, DU3TW

Open up the radio and remove one cell from the battery.  Now put the cell back in. Radio should power now.
