Digital display goes dark from time-to-time...

That device uses an electronic oscillator and it may be that one or more components inside it are failing. Unless you have special tools and knowledge, there is nothing you can do to repair it

U might just have a bad connection inside that intermittently opens.

Those displays can and do fail. Often as time goes by they get dimmer and dimmer.

Hi Jason. Have you performed the following actions?
Electronic Timing Center (Analog Clock w/Digital Display)
Synchronizing the analog and digital clocks
1. Press the "timer" and "start time" buttons simultaneously.
2. Turn the set knob to move the hands on the analog clock to any time setting.
3. After five seconds the display will go blank. Press the timer button and using the set knob, set the digital time to the exact time on the analog clock. This will synchronize the two clocks. You can now set the time of day.
Setting the Time-of-Day
The time-of-day must be set before any other program can be used. When your oven is first connected to the power in your home, the digital display will show 00:00. To program the time-of-day:
1. Push and hold the "timer" and "bake hours" button at the same time.
2. Turn the "Set" knob until correct time is displayed on the digital clock.
3. Release "timer" and "bake hours" button
The analog clock will automatically set after the digital time is set

Let me know so that I may follow up if need be.

Hi lufberg,

I see you need help with your radio controlled clock.

Place your Seth Thomas atomic clock face-down on a table or desk and locate a series of buttons labeled "PST," "MST," "CST" and "EST" on the back of the clock. Press the appropriate button to set the time zone.

Turn your attention to the small lithium battery-powered digital clock display on the back of your clock. With the correct time zone set, the digital display should accurately reflect the current local time.

Locate the AA battery compartment on the back of your clock. Put two new AA batteries into your clock's battery compartment.

Set the "Mode" switch on the back of your Seth Thomas atomic clock to "Run." Wait for it to adjust to the correct time. The automatic time-adjustment process can take up to 45 minutes, but is usually completed much sooner.

I hope this will help.

Thank you for choosing Fixya,

A couple of possibilities- If there is no fuse holder on the rear of the box, it may not be user-replaceable but soldered onto an internal board. If it has blown, either there has been a component failure in the power supply that caused the fuse to fail or the supply is not starting up as it should, a problem caused by cheap capacitors in certain areas of the supply. Unless you have at least a multimeter, this is not a good choice as a DIY repair.

I can't find a manual for this but my guess would be there is a setting for the Display to dim it at all times unless you touch a control.

you need to set the date and time.

press your "mode" button 5 times until it says on lower display "H-SET". Then press the "adjust" button until it beeps.

Now hold the "forward" button and the minute hand is moving.

Enjoy :o))))
