Denon D-M31. It's had a problem for a while where after a minute or so the volume control on the front works very intermittently. The remote control volume contro; still works fine though. I have heard...

Hi. It's called a rotary encoder.

You might get a replacement from Denon if you have soldering skills or can find a part number in the service manual. I'm unable to access the site just now:

Denon UD-M31. Circuit protect mode permanantly engaged.

Denon UD M31 CD not playing

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.
