Service Manuals

In our quest for obtaining new features and updates for our beloved Denon DJ equipment, we seem to forget the importance of service manuals as a tool for troubleshooting the equipment and maintaining it in working order. The availability of service manuals reflects the manufacturers professionalism and offers long term support and peace of mind for the customers. I invite everyone here and especially Denon DJ staff to give their opinion on service manuals necessity and propose some details to be included inside the service manuals, like assembly schematics, troubleshooting and servicing procedures with illustrated images, electrical schematics and service parts catalog numbers. All of Denon DJ new generation equipments are in use for quite some time and sooner or later they will need some servicing, especially those who are outside the warranty period.


Companies these days don’t want people repairing equipment, they’d much rather you threw it in the bin and buy the newest version.

It is however very easy to get Denon spares in the UK anyway. I have ordered lately and found the process to work well.

My opinion is Service manuals should be made available to genuine authorised service centers only.

This is hi tech gear and sometimes needs specialist test rigs, test systems or special tools to open, disassemble, get true, meaningful readings, fix and reassemble.

An what are we supposed to do, accept this state of affairs knowing it is not beneficial or try to communicate with our equipment manufacturers in order to convince them what is professionally correct?

The least I know the better. As long as I keep feeding the beast inside my Prime 4 with music “it’s happy” as long as it’s happy I’m happy :smiley:

But if you’d like to believe you can change the world with a single mouse stroke, go for it.

It’s lovely to float along thinking that every product should have amazing free updates every month, for at least 10 years after it came out and that the world should tick the way you want it or expect it to, but reality doesn’t work like that.

If our shoes never lost their shine, and never let the water in, an colour changed to co-ordinate with whatever clothes we wore, we’d never buy a new pair of shoes. See conspiracy theories for car engines plans which could do 1000 miles per gallon right now, but the plans have been bought and buried by the worlds petroleum companies to keep us buying petroleum…

I suppose many of you here still have some old hi-fi equipments in your collection, that is still capable of doing the job well as long as it is serviced regularly, even by you, as long as you posses some technical skills. Also, the new generation equipments can still be serviced in professional electronics repair shops as long as the technician can be provided a service manual that will help him understand better what’s inside and what needs to be done. Personally, I service all my equipments on my own based on existing service manuals and only occasionally send them to professional repair shops. In my opinion, the decision to buy new equipment should rest on the customer and not be imposed on him by lack of support or spare parts. I don’t try to change the world, just want to have the option to know what is inside the equipment, understand better it’s function and be able to enjoy it long term, especially because it is labelled as “professional”. In today’s world when someone has the option to order online just about anything and ship it almost anywhere on the globe, where you don’t see authorised dealers or authorized brand repair shops on every corner, having a service and repair manual available can make the difference between solving a problem and tosing the equipment at a disposal site.

Been running this amp since 1989 and it still works great. Don’t think my MCX8000 will last that long lol

Having a service manual for the MCX8000 would surely help keep it running a good amount of time with the proper attention.

You mean that if the service manual is placed within so many centimetres of the mcx8000, some magic field of well being is generated?

Loving the idea. Again, just needs a bridge to reality

The fact that you have the service manual could spare you some pretty good amount of time and money. If the “bridge to reality” means that a professional piece of equipment is some kind of one-time use item, something is wrong with the word professional put in front of a piece of gear. Of course, there are people who choose to just buy knew and updated equipment every two or three years, but, we must not forget the fact that not everyone is Paul Oakenfold. Part of the challenge to “change your rider” should include some good looking at the competition also and understand what they are doing well and learn from it.

You must have a bad memory, you’ve mentioned the availability of manuals several times now.

Yes, I do, and that’s no accident. I mentioned the necessity of service manuals several times hoping that as many of us understand their usefulness and help Denon DJ to take the steps in order to release them.

Nobody from Denon really visits the forum any more. Chloe is gone, Gary is gone, Paul hasn’t been seen in ages and it’s only the software engineers who post very infrequently. I wouldn’t hold your breath…

Well, this forum is supposed to be a way to communicate both between users and with Denon DJ officials. It is Denon DJ who created it, after all. Am I wrong to expect feedback and discutions originating not only from us? Denon DJ embarked on a potentially successful road and set itself ambitious goals. In order to achieve these objectives, keeping a good flow of information between the company and the users and earning our trust and respect, day by day, is part of the road to success. Denon DJ should dare to be different from others, in a good way.

I completely agree, but that has been lost. Paul made lots of promises that were never really fulfilled but now there is very little communication at all.

All of Pioneer DJ’s service manuals are available. That and the fact they build stuff like their CDJs to be relatively easy to take apart and repair are some of the contributing factors behind their longevity in the industry. They are trusted by DJs, sound installers, and repair techs, and these can often be the same in-house people.

Sorry, that wasn’t meant directed at specifically kradcliffe, rather the whole thread.

I have taken the MCX8000 apart several times and it is an absolute nightmare. Even to replace a deck fader takes hours. The bad part of this is that even if we send the unit back to Denon there’s a huge time based labour charge.

This is exactly why I promote the necessity of the service manuals. I don’t mind that a certain service procedure requires time, as long as I know it can be done, either by myself or at a professional repair shop from my area. The unit is designed and put together by people, so people can put it apart also and repair it. It is the time spent shipping and waiting and the cost of the labor at the manufacturers repair facilities (many times outside a country) that you can avoid. The manufacturer can make money from spare parts sales also and the owner can retain the value of the equipment. Ensuring a good supply of spare parts for your products keep the customers happy and allows the manufacturers to better focus on developing and thoroughly testing future product releases.


I agree with the service manual, my mcx8000 still has a year of warranty and I have not sent it to the workshop because of the problem of freezing the screens when putting them at 100% because I get more expensive than buying a new controller Since I should send it to another country, I am an electronic engineer with the service manual I could solve the problem myself that if I remember correctly it is just changing the memory modules or something like that
