My Replay is working just fine except the blue light doesn't show on the front of the unit any more. Is there a way to fix it? I'm not anxious to crack it open if there isn't an easy fix. The light just stopped working one day (like a light bulb that goes bad). The unit responds to the on/off and remote and works fine. Records fine, etc. I just can't tell if it's on or off until I turn on the TV.
