Opening NS3

Postby jjdnord » 24 Nov 2019, 19:54

During a gig the other night, a small piece of a quarter-inch cable went into my NS3 after a tragicomic accident. I was thinking about opening up the Nord to remove the piece. Any thoughts? Good idea? Bad idea? It looks fairly straightforward but I would be worried about voiding the warranty or not being able to properly secure the top back on.

Thanks so much for the responses. I don't know how to isolate the power supply so it's probably not a great idea for me to handle on my own. I called the shop where I bought the Nord and they said they'll take care of it under warranty. If I mess something up, they said, the warranty is voided.

I think the other two posts may have made the power supply thing seem more dangerous than it needs to be...
Just:
a) make sure you've disconnected the mains lead from the NS3...!
b) leave the machine for a few minutes (after you've last had it switched on) so that the large capacitor that Lewis mentions discharges itself.
c) once open, still keep your hands away from the power supply board just to be ultra-safe but really there shouldn't be any problem even there as long as you've done a) and b).
I personally feel that Nords are some of the easiest boards to self-service that I've ever owned (along with Kurzweil).

Having said all that, only open up your board if you feel confident in your own knowledge/ability.
If in doubt, do as you've done and get the shop/dealer/distributor/whatever to do a warranty repair :thumbup:

Yeah, I'd forgotten about the Rev 2 Prophet 5 I owned decades ago. I've still got the complete service manual! :)
The one machine I've owned that I wish I'd never sold :(

Well, thanks to everyone's encouragement, I took care of it myself and am happy to say that the "foreign object" is out of the Nord and all is right with the world. I saved myself close to four hours of driving back and forth for the service, as well as the potential 3-week wait time.

That said, I was able to do it without removing the ribbon cables. If I had to take that step, I would have brought it in for service. Just too much to risk given the cost of the unit.

Thank you all for the question and info. I read this post prior to opening my Stage 3 Compact to remedy a rattle when I played. The process is indeed simple and straightforward. Remove the three screws on each end, remove the seven screws on the back cover, remove the single screw in the middle of the bottom. I carefully tilted the cover up, identified the loose screw causing the noise, and tightened it. Done quickly and painlessly.
