We've got an older Mt. Vernon AE Insert ('06-07). It hasn't been used in over a year. Our wall display is now completely dark. When functioning correctly, just the numbers & letters will be dark & the background will be light-grey. If we push on the display screen or use a flashlight, you can see the display. Any thoughts? Please. Thx.

Jake, I'd start by checking the t-stat wiring at both the stove end and also the t-stat itself. The wire is thin and not that flexible. Good luck.
