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 segment might light on another menu item.

Now it's started going dark during testing 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, and it passes all the part 1 voltage tests.

What should I do?

Thanks,
