Frank,
It sounds like the MCU is getting "mixed up". Try doing a Reset to
Factory Defaults.
See page 69 in the manual. It is a 2 step process.
1) Hold BAND and MENU together and power on - release the buttons after
the LED test. E09 should be displayed.
2) Turn power off, then back on and you should see E10. Tap any switch.

I'm building a KX1 and finished Part 1. I encountered problems during
testing.
First I noticed when scrolling through the MENU items some some segments of
the LED display don't light on some menu item names. However the same
segments will light on another menu item so it doesn't seem to be a problem
with the display itself. Also, tuning with the encoder and band switch
displayed as expected.
But now the display started going dark during tests and not coming back on
after button clicks or encoder turns. When it does this the 5v and 6v lines
still have correct voltages and nothing feels hot to the touch. The only way
to get it to come back is to turn it off and wait a while.
I've carefully checked parts placement and solder joints and can find no
problems so far, and it passes all the part 1 voltage tests.
