It seems like you're experiencing an issue with your Panasonic microwave oven NNT551. If the clock button is not responding and you only see two dots when pressing the stop button, there might be a few things you can try to troubleshoot the problem:

1. Power Cycle the Microwave:
   • Unplug the microwave from the power outlet.
   • Wait for about 30 seconds.
   • Plug it back in and try setting the clock again.
2. Check for Child Lock:
   • Some microwaves have a child lock feature that can prevent certain buttons from functioning. Check your manual to see if your model has this feature and how to disable it.
3. Reset to Default Settings:
   • If there is an option in the manual or settings to reset the microwave to its default settings, try doing that.
4. Inspect for Physical Damage:
   • Ensure there is no physical damage to the control panel or any other part of the microwave that may be affecting its functionality.
