Model 00509 no longer displaying temperature

I received this unit as a gift a little over 3 months ago.  It had been working perfectly up until a few days ago when the temperature wouldn't change from 17 degrees.  I unplugged the display and plugged it back in and now two dashes are displayed instead of a temperature.  I replaced the batteries in the sensor with new energizer batteries, and that didn't work.  I've tried all the other recommended steps, like unplugging the display, moving away from any electronics, replacing batteries in the sensor, then plugging in the display with the sensor nearby.  I even bought a new sensor thinking that was the problem but it wasn't.  

Whenever I unplug the display and replace the batteries in the sensor, the signal bars will cycle through for a few minutes and then go away.

Any other suggestions?
