Last number brighter on DVR time clock

I recently installed a new DVR. It's the main one in the house. Since I've installed it, the last number (seconds number place) on the time clock is twice as bright as the other numbers. The other numbers are dimmer. Actually, it's just the top line or the top side line (one of the other) that is brighter on the last number. Again, it was like this when I first installed it. I want to make sure sure there's no shirt circuit or other issue.
