NPC display is acting wonky

Hi, my NPC seems to be acting funny. It’s on the latest firmware revision level, v0.55.

The is possibly acting up in that it doesn’t stay active as long as the settings would indicate it should. The display winks out in probably less than ten seconds regardless of the time selected be it one minute, ten minutes, etc. or Auto. Once it goes blank the only thing I can do to restore it is to power the unit off and back on again with either the power switch or pulling the AC line completely from the unit. Even though the display is out the A to D converter seems to be functioning properly.

I’ve tried the reset button but that doesn’t help either. Do you think it would be worthwhile to reload the firmware just to be sure something didn’t get corrupted?

Please let me know.
