Is it possible that you inadvertently turned the display off?

my guess is the light burned out
We had a few power outages in the last week when this happens the unit remains powered on
The most recent power outage happened during the night and since my stereo is in the basement the unit had been powered on for a full day
Does it make sense to open up the unit and see if the light is burned or should I get a technician to look at it
as it's not as simple as it seems
The display of the Denon 2900 is not LCD; it is FLD which does not require illumination light. It produces light on its own.
Since the player is still functional, you should really check the settings as there is "Display OFF" function. If this is not the case, then the filament or cathode voltage for the FLD is the failure (power supply), or it may be the FLD driver or the FLD it self (very unlikely). This requires troubleshooting by experienced Tech.
Why not just call/email John Tucker? He may have the answer. I had the same thing happen to a DRA 245 receiver about 10 years ago and at the time, Denon designed the unit to be serviceable by only a technician. Can't imagine that sort of thing changing any. The display should last years, in my case it lasted about a year and a half. Before I would go to a technician though, I would try Krelldog's advice and go through the various on-screen set-up menus ... just in case.
Bluemike, given your FLD display tube is still fine (which I am almost 100% sure it is fine), I'd say that the repair should be in the $200 range, max. Depending on your location shop rates, you may even get it fixed for as low as $70.
If for some reason the FLD has gone south, then it will cost more as the FLD is around $100-150 from what I know. You need to check this though.
Good luck fixing it! I'm sure it's not that bad.
Reporting back once more on my problem ...
When I look at the front display there is a dim light when I turn it on vs when it is turned off
however the blue lighting which shows the tracks and all other information is not illuminateD. The screen is blank
Do I need to send the unit back to Denon
I have not e mailed John Tucker as the unit was bought re sale here at Audiogon.
Any further input is appreciated !
Don't know if you have a user's manual or not ... here's the link for one . Refer to the last page (page 34) under troubleshooting. Maybe the thing to do is to reset everything back to the factory settings. The display is factory preset to "on." If you still get no display ... then it's back to Denon.
