Hi,

Have you unplugged it from wall since ?
and, do you know if maybe the speakers are blown?
Bad speakers will make it stay in "protect"
Try other speakers after the unplug-plug back in routine.
Try the Denon website for a manual

I got on my 2007 m50 to go for a ride ,turned the key and get nothing ,fuses sre good


Is the battery good? Try the headlight while you crank the engine (I don't know what an m50 is so...) If the headlight goes dim or out when you crank, the battery is shot, has a bad ground, or connection to the starter. The starter relay, ignition circuit to the relay etc. could be faulty. Pull on the wires while you crank, sometimes that helps identify the problem.

My NAD T65 receiver has problems with the digital sound input. The sound gets choppy when I increase the volume. It seems to be ok at very low volumes, but as soon as I crank it up it fails. It happened...


Could the amp be showing distress, clipping, going into protection? There really isn't much reason for volume of a digital input to have an effect unless the room is shaking so much it's upsetting the digital source device's tracking.

Hi, My Marantz SR4200 goes into protect mode about 45min after cranking the volume up to party mode, ie above '0'. It is getting worse slowly. Ok at lower volumes. Something seems to be overheating,...


Or it could be you're overdriving it, hence the heat. Take a clue and turn it down. At 70 wpc played loudly it could be going into speaker- and self-damaging distortion.

Make sure it has a lot of ventilation.

There are lots of reasons for this, you don't match the ranking requirements, the room is full, network or host error. Nothing to worry about, just try another room.

Denon UD-M50 cd changer. Need help extracting drawer for home repair!


Hi KathyKate

If you are still having the same problem with your denon UD-M50 I might be able to help. I have fixed a number of them in the past and have the necessary maintenance manual and knowledge of a company that can supply spare parts. Disassembly looks very complex, especially when the problem is with the carousel but once you have an understanding of the mechanism it's not that difficult. Care should be taken when manually removing and reloading the disc trays as damage can result to the 'Teeth' alongside each. Spare trays are available. All my repairs involved the removal of the carousel mechanism in order to align the trays. I can copy the relevant sections of the manual dealing with the re-alignment which is critical but again if followed exactly you should have no trouble. If you respond with an Email address, I will be only too pleased to forward you the schematics etc.

The tact switch behind the panel is being pushed in by a defective front panel button, the small switch is bad behind the button, or the volume control IC is bad. Good Luck
