2007 Accord stereo backlight doesn't work
 

The stereo on my 2007 Accord works fine, but the backlight stopped working. The lights on the a/c and heater just below it work fine. The dashlights work fine, its just the stereo backlight. In the daylight, everything is normal, its just when it gets dark out that I can't see the stereo numbers (ie 105.7, etc). I tried adjusting the dash lights, but that made no difference.

I read about a similar problem with the 2003 Accords, and a service bulletin, but nothing on a 2007 Accord.

I installed a Parrot bluetooth device about 4 months ago, but everything worked fine til about a week ago.

Thanks for any ideas.

That is internal to the head unit. Unless factory wiring has been compromised. You can check fuses but i don't expect the solution to be that simple.
