Denon MCX8000 freeze

Legacy Products Controllers
1

Hi everyone,

I’ve seen a lot of great discussions about the Denon MCX8000, but there’s one topic that doesn’t get talked about enough…

Has your MCX8000 ever completely frozen?

I’m talking about situations where:

• the displays go black or stop updating

• pads and buttons stop responding

• cue/play buttons no longer register

• the controller seems “frozen” and you’re forced to reboot it

It’s an extremely frustrating experience, especially in the middle of a set.

So I’d like to ask you directly:

• Does this happen to your MCX8000 as well?

• If so, how often?

• Have you found any solutions or tricks to fix or prevent it?

I’d really appreciate your feedback. Thanks!

Are you using standalone or DJ software?

I still use the MCX8000 regularly (probably 90 percent with VDJ and 10 percent standalone) and have never had issues as you describe on either of the two units.

The MCX8000 has form for certain problems relating to ribbon cables and connectors coming loose. It could be vibrations causing this, so I would dismantle the player to the point where you can lift up the main board at the back (the one with all the audio connectors) so you can unseat and reseat all the cables from that board to the one underneath and the individual player boards, although if the whole unit is freezing it’s unlikely to be those.

If you need some help with how to dismantle the controller hit me a PM and I’ll talk you through it.

A batch of mcx8000 had a freeze problem which was traced down to one batch of a minor display support chip being less tolerant than normal.

There was a spate of users claiming that reducing the brightness alleviated the issue but ultimately InMusic swapped the chip for any units affected - I don’t know if they still do, as the unit is very old now (10 years or so) it it’s worth contacting your local InMusic repair centre for advice.

The display freeze issue is not related to the symptoms the OP is experiencing. When it happened it was just the screens not booting up or freezing where they are also having pads and play/pause buttons not responding too.

Hi homeland101,

I’m contacting you regarding the issue I encountered with the Denon MCX8000. I use the console in standalone mode, as I don’t use any DJ software.

Could you please help me set up the cables as you previously suggested?

Thank you very much for your availability.

Best regards,

I contacted my local InMusic service center, but they told me that it is not recognized as a manufacturing defect. According to them, it is not covered, and I would need to pay for the repair myself. I don’t understand why it was repaired for other customers after the issue was acknowledged, but in my case it is not being recognized.

I would argue that as lots of other people have had free repairs. You need to make sure it’s the same issue though, I don’t think what you are describing is related to the screen freeze problem.

Inmusic will know from the serial numbers which mcx8000 had the iffy batch of display driver chips - it may even be that they know how many of those chips they’ve replaced already and would know if they’ve completed that task.

There are plenty of other faults which could befall any electronic device and cause it to ignore button presses, lock up etc
