Help with K3

[Roger D Johnson]

Well, the "edit as new" didn't seem to work!

The rig with no front panel LEDs working is a K3.

I do have 5 volt power to the LEDs.

73, Roger

Roger,

It may be that the driver IC for the LEDs has been damaged.  There is 5
volts on the LEDs, but the driver IC has to bring the other lead near
zero volts to light the LED.
If you did not work on an anti-static mat when doing the connector
change, that may be the blame.
But just the same, re-check the soldering on the connectors you changed.
