Hi,

as well as being a different model it sounds like a different problem as well. Possibly fuse related but on your pics I can't see anything with the same naming conventions as on the UDM3 (where the fuses seem to all begin with PR)

Sorry I can't be of help, I'm no electronics whizz and I just followed fatz2000's excellent post to the letter.

Hope you get a fix.

i have done the same repair to my ud-m3 as in listings. works perfect. no need to drill holes for wires as is gap just above the circuit board to the side then used pin nose pliers to grab the wires.

Hi found a post on the forum re cd tray failure - I have my daughters unit which has failed - I suspected the grandkids had stuffed something in and took cover off but nothing obvious - I am not very technically capable - would you be able to look at unit and see if it's repairable - will pay of course - I live in wokingham and daughter is in Epsom so we pass by Woking regularly - especially when the M3 is shut!! Hope you can help - cheers - Ian

DENON UMD-30. A very clean and smooth sounding unit. The design is classic and display is adequately bright. If you're limited for space and budget, this is the ...

I thought my denon UD-M3 was ready for the bin (no cd eject problem), but I emailed some chap who sold one on ebay with this fault - he said it was a fuse somewhere too.

Took my unit apart, and I mean apart. All the boards out etc. The previous post regarding the PR003 is spot on. These are fusable links, they look like brown resistors with only a number. In this case 500 (ma).
Mine was open circuit as expected.

The location of PR003 is on the underside of the main board. As you dont have to remove the failed component - you can solder a new fuse on the topside.

CHECK YOURS IS OPEN CIRCUIT FIRST. I did this whilst the component was on board since it should be a short circuit.

Heres are piccys of my fuse in place. You can see the PR003 markings on the top side of the board.

I've used a fast blow 500 milli-amp fuse (40 pence each), and the unit is working fine now.

Obviously do all of this at your own risk!!

Hi, My Denon UD-M3 is not able to play commercial music CDs. It skips, repeats a section continuously, freezes, etc. In desperation, I've tried a high-quality cleaner to no avail. Anyone with instructions/suggestions on how to replace/repair the CD drive? Any ideas? Thanks.

I have been looking for this information for a long time, I was very surprised when I found it here.

Discovered this string while in the meantime inspecting for a fix for my Denon. Thought I'd give it a go despite having NO understanding of electrics or verifying. Picked to place an in-line merge holder thusly expected to change the gathering plate undercarriage irrelevantly to suit it.
