Hi @dborlase ,
What happens when you press the Dimmer button with the radio Off, does the display come back on again?
This is from p.18 of the user manual for the clock.
ADJUSTING LED BRIGHTNESS You can adjust the brightness of the LED display making it brighter, dimmer or even turning it OFF when the radio is OFF. There are four dimming options available: HIGH/ MEDIUM/LOW/OFF (Standby). Press the DIMMER button to toggle between the four brightness settings.
Here’s an image to show you the button

if it still doesn’t show a display and allow you to set the time/alarm etc try a power reset and see if that works.
Disconnect the AC power from the clock and also remove the backup battery. (see p.11 of the user guide - take note of the orientation of the battery so that you re-insert it the correct way).
Wait for a minute or so to allow all the power to dissipate from the clock and then re-insert that backup battery and reconnect the power to the clock and check if it now operates OK.
