Assembling my K1 and got to the part where I check the side tone and all. No side tone in the ear buds. I also noticed that when I key the keyer the display goes blank. Not sure why no side tone. Checked the schematic and it goes back to the MCU.  Could I of missed something? I have an illuminated display and this stays lit. I would appreciate any help.

Thanks
