Nord Lead 3 acting very strange

Post by melech »

Hello,

My Nord Lead 3 has started to make very random noises. It's got a total life of it's own.

There's no midi plugged in and I have plugged my headphones into it. It is not happy at all.

Is there anything I could try before I send it off to get repaired?

Thank you

Hello and welcome to NUF,

that can be due to many things, you could try to open your NL3 and check that at least there is no loose flat cable between the boards and from the Power Supply Unit (unplug and reseat each of them on both sides, applying some contacts cleaner on the pins just in case they are oxydated); if still not working properly, it could be a different hardware (PSU or mainboard) problem that needs to be diagnosed by a qualified technician.

Thank you. I tried that (it was very dusty in there) but it is still not working correctly. I'll get it sent off for repair.

You did the right thing, good luck! Keep us informed whether the repair was successful :thumbup:

Hy every nice persone on this forum.
As I'm totally new here and also a new Nord gear owner - have had a used NL3 for just a week.

Unfortunately there seems to be some serious stuff going on with this synth of my dreams. After some time not just playing, but more programming the synth; changing osc shapes, filter types etc, some dsp crash takes place. Namely every certain number voice, like 4th or 5th makes some totally random sound.

What would be the most sensible steps to diagnose the problem? As I'm completely blind, I wouldn't able to carry anything serious out myself, but I have friends totally good with electronics and I can certainly share instructions and information. I hope my Lead isn't dying, as it would be devestating news after 20 years of waiting and finally getting the instrument.
