After replacing a channel fader on my Denon Prime 4 I tried it out and everything worked. Then I put in all the screws and suddenly everything started glitching out when I turned it on again.
Often the lights flicker and they’re the wrong color when not, only a few buttons do anything and they usually do the wrong and multiple things. The view button in particular seems to do a lot of different input, automatically loading in random tracks and opening the source selection screen. The jog wheels seem to work flawlessly however.
I have tried loads of things like unplugging data cables within the controller and trying again but nothing has helped so far. Has anyone got experience with this?
Sounds very much like a bad internal ground problem.
Check that you have tightened all the screws under the chassis of the unit. If some turn infinitely or cannot be tightened completely, this may be the problem.
Some screws, especially those located at the horizontal axis near the center of the unit, play a vital role in grounding.
What do you mean by residue? What kind of residue?
Some screws under the unit fix plastic against plastic, especially most of those going around the unit near the outer edges. These screws therefore do not have a big role in grounding.
On the other hand, there are other screws that fix metal against metal, especially all those that are under the central part of the unit, often screwed into a very deep hole.
It is possible that the residue you are talking about is plastic residue. It is also possible that when reassembling the unit you have interchanged screws that were previously in a plastic against plastic hole and which are now in contact with a metal part.
It is therefore possible that these residues prevent good conductivity in the screw holes that help with grounding.
Try cleaning the holes and screws with a cotton swab soaked in isopropyl alcohol to remove any residue and see if that helps.
Firstly, you must entrust any repair of the device to competent and experienced specialists - an authorized service center.
You should not repair these devices yourself. You are not trained to do this and you probably do not even have a service manual at your disposal.
You made a mistake somewhere.
Pack your Prime 4 and send it for repair to the nearest authorized service center.
Or to an experienced service technician who has sufficient experience in repairing such devices and also has the necessary technical service equipment and service manual at his disposal.
Do not seek advice on servicing Denon equipment on this customer forum. There are no service technicians available here!
Didn’t seem to work, one thing I just remembered is that one of the cushion thingies on the mixer assembly fell off and I reattached it but in the process I may have put too much adhesive on it preventing contact. Could that be the issue?
Edit: When I started the controller up after reassembling it it mainly had issues on the left side, the same side of which the cushion fell off.
Do you work for Denon? If you don’t want to take your equipment apart then don’t. But if this guy wants to fix his own stuff then either help or get out of the way
You need to double check the entire assembly looking for loose connections or something left unplugged. Clean all of those contact points and their screws with rubbing (isopropyl) alcohol. The higher the % the better but in any case let it fully evaporate before assembling. Not sure what the residue is but if you think it is messing with connections the alcohol might take it off or you can try a pencil eraser.
I’m betting on a loose connection somewhere. Double check all of them even if you didn’t intend to disconnect one it may have yanked loose when taking something else apart.
It’s time to take or send the unit to an authorised Denon / InMusic service centre.
Primes are not like the big hollow amps, lighting controllers, hifi components etc from a couple of decades ago. Instead of a single PCB bolted or pressure clipped onto the door of the casing, with lots of space around each component, modern gear is based on multiple PCBs adjoined with low profile clip/clamp cables with overlaying PCBs which must be relocated exactly when the unit is reassembled - allowing a short to occur is easily done, and can damage anything from one component to multiple boards.
Sometimes trying to swap out a 20 buck fader can accidentally and unwittingly cause hundreds of bucks worth of damage.
Best to get the unit into a repair centre before that (or worse) happens.
I’ve already looked it over multiple times but I will again just to be sure. I’m also gonna double check the ribbon cables connecting the mixer to the left and right assemblies.
Could a single loose connection cause so many issues?
It’s time to take or send the item to a service centre - these aren’t the big old hollow lumps of kit from the 1980s and 90s - they don’t lend themselves well to DIY repair attempts
En el proceso de volver a montar todas las partes, seguro que alguna de las fajas de unión de las placas hacen mar contacto. O la cinta marrón, que une la pantalla LCD con la placa ,al montarla, si no se tiene cuidado, puedes haberla dañado y este produciendo algún cortocircuito de alguna de las 32 pistas que tiene. Si no se tienen conocimientos avanzados y suficiente experiencia en la reparación de equipos electrónicos, mejor estarse quieto
