Digitrax DT400r

[IOGO]

My DT400r controller has a blank screen when I plug into my layout. I have read the manual and cannot seem to find any way to "reset" the controller. If anyone has seen or experienced this with a DigiTrax 400r controller, please let me know if there is a way to correct it or do I need to send the unit in for service? The controller is not new and has been working flawlessly for the past 2 years.
Any help or insight is appreciated.:confused:

Does it have a battery for the memory/clock?

I recommend sending it back to be look at to the factory. I had the same problem but for 2 quick seconds when something happened.
