The unit will not play a CD in the normal horizontal position. If the front is raised so that it is tilted at about 20 degrees to the horizontal then it works perfectly. Is there a simple solution to the problem?

Re: Denon UD-M3 CD Receiver CD playing
Sounds like your spindle motor is shot. What happens is, the bushings in the motor that turns the CD disk are worn. So tilting the unit will change the loading of the motor shaft to an " un-worn" spot on the bushings and the CD plays properly. The spindle motors are chepa for the most part, but the labour might bite you a little because it is a fairly involved job. If the unit is still under warranty....great...if it is just off warranty, you may get some good will service from Denon......best of luck...Rob

I would replace the audio cable from the CD player to the Denon amp, a long shot, if you have other devices hooked to the amp and plays fine, the problem will be in the CD player. However! if all sound sources have the same problem, the issue is with the Denon unit.
Usually when a receiver goes into protect mode, there are several reasons, One is there is a bad speaker connected to the unit, this will cause the unit to to into protect mode, try disconnecting all speaker from the unit and turning it on if it does not go into protect then one of the speakers are bad. Another reason is the power output Amplifier IC is shorted inside the unit. Another reasons could be that speaker wires are touching each other and causing a short. Disconnect all unit connecting to the unit and try turning on, if it stays on and no protect then connect them including the speakers one at time until you determine which is causing the error. If it goes into protect with nothing but the unit on then the Output IC is bad and the unit needs servicing.
1. press the menu/set button on component to select display mode 2. use the +/- button to set the time mode (AM 12:00 blinks) 3. press the menu/set button for at least 2 seconds (the hour will start blinking) 4. Use the +/- button to set the hour, must roll the hour to change am/pm 5. press the menu/set button to switch to minutes 6. use the +/- button to set minutes 7. press the menu/set button to finish setting the time
The problem is in the mechanism,maybe when you put another disc while playing that is cause. There is a misaligment there in the tray you better checked it out,and also the lense by using a cotton buds.thats all for now Hespbb....
It is possible that the laser has gone, the part you require is:
Sanyo SF-P101N CD Mechanism - 16 pins (there are 15 pin versions available which have the same product number, the two versions are incompatible)
i have found the part on Ebay (UK) for less than £5, the shop that sells it also suggest replacing the flexible strip that connects that mechanism to the circuit board, the strip costs £2 and replacing it would seem to be a very sensible idea seeing as you have to completely strip the unit to replace the mechanism.
My UD-M31 is in bits on my work bench at present, awaiting the arrival of a new mechanism, i'll post again if replacing it solves the problem.
