Question about Bose & Wave& Music System
My denon udcm m7 personal component system cd player often gives an error message (ERR) when I hit play or eject on all three disc. I have to keep turing it off and trying again before it actually, randomly plays or ejects. Since Denon no longer has parts for this system, before I pay for a service center diagnosis, does anyone know what this might be? Has been doing it since I got it (refurbished) in 2000, but doing it more so now. OR does anyone have a replacement I can purchase?
Thanks, M in So Cal
Try cleaning the laser first. Take care, because it is delicate.
Some instructions of how to clean a CD laser:
If the cleaning does not fix the fault, it is possible that the laser is weak, or there are some problems in the electronics in the CD player. This is not something you will be able to service yourself, unless you are properly trained, have experience, and have the proper setup to perform CD player servicing.
In most cases these CD players are not cost effective to service. You can contact the orignal manufacture for details or any recomendations.

I turn the machine off, then turn it on, and lightly smack the machine on the side as it's turning on. You'll hear it catch and then start without the ERR. I've been doing this for about 2 years when it gives me a ERR message and although it's cheesy and clearly not right, it works every time.
