Loose part moving inside my new NS2 (Pablo?)

Floating part inside NS2

Hello everybody,

I just started packing my stuff for a rehearsal, when I noticed a sound when I lifted my Nord Stage2 from the stand.
It appeared to me as a part that somehow got loose and started moving around. All keys seem to work just fine, as well as the sound.
After a little while, the moving part seemed to have stopped, but I wasn't reassured. So when I tilted the board a little for a second time, my worst fear was true: there was something floating around inside. Very carefully, I removed the screws on the left and right panels, as well as the small screws on the back. I left the ones on the bottom alone. That way, I was able to very gently remove the floating part. It's a small white thingy, seems like some sort of weight. See included pic.
How deep am I in trouble?

How deep am I in trouble?

Not a whole lot I think.

That looks like a key weight to me. It probably came loose in one of them, a white one most likely. You should be able to feel a difference in that key. Depending on the damage, if any, you might just be able to glue it back. I think that the worst case scenario is replacing an entire key, but I doubt that's really necessary unless a key is cracked/fractured due to stress or something.

Is your NS2 still in warranty? It seems to me this should be something covered under warranty, although a shop might insist it is not. Seems to me that unless you really hammer on the thing (which would surely cause visible damage) that it should be able to cope.

It is of course possible that these things are not actually glued in place, but that the weight is held in a two-part plastic holder that clicks shut. In that case the key might have some damage, but even then I think it could be glued back together again.

Pablo should be able to give a more informed answer. I never had a HA version of the NS2 myself, so I've never seen how the keys for the HA key action are constructed.

This exact same thing happened to me with my NE3 a while back. With Pablo's help I was able to remove the cover and epoxy the weight back into place. It never came out again.

Thanx so far for the responses guys!
Glad to know that it is 'only' a key weight. I really tested every key seperately and can't feel any difference. And yes, my NS2 (sw73 btw) is still under warranty, so I'll contact the store first.
Keep u all informed

Oh Pablo, if u read this: I would also like to know how to remove the cover properly, just in case

EDIT: the shop owner told me that servicing this particular problem is still within warranty

It should be pretty easy to find info on this in the Stage section, as it has come up several times in the last two years

Hi BF,

You did say SW73 version, yes? If we can momentarily remove C-series organs and HA action Nords (76- and 88-note Stage models and 88-note Piano/Piano 2 models) from the discussion, all Nords open pretty much the same way:

1) flip it over and identify two parallel rows of screws running width of instrument. Do not disturb them.
2) identify any and all screws which are outside of that dual parallel row pattern (usually only one). Remove them.
3) set it back down in playing position
4) remove all screws on rear of instrument along seam between red upper lid and black lower chassis
5) remove all screws on ends EXCEPT for the pair, one each end, which is nearest to the bottom rear of instrument
6) loosen that pair ~1 turn

In this condition it will be possible to grab the ends and lift -- the entire lid will lift like a hood (bonnet for you brits) on a car. Be conscious that on 73-note Stages the mod wheel / pitch stick assembly will impede the travel of the lid considerably, but in any case it will be possible to lift the lid far enough to get a hand in there and disconnect ribbon cable(s) connecting mainboard to panelboard(s).

7) disconnect panel ribbon(s)
8) remove last two remaining end screws
9) remove lid entirely and (this is important) put it aside IN A SAFE PLACE where no small children, wagging dog tail or other hazard will befall it. Exposed electronics are most vulnerable to damage

Unfortunately, for the job contemplated in this thread, you're only halfway there. You'll want to remove the entire keybed in order to conveniently inspect the underside of those keys, not only to locate the key which is missing its weight, but also to check the rest of the weights to ensure that they are all stable (dropping weights is actually quite rare, so you are not likely to discover more problems, but it will be good practice to double-check).

The second half of this operation, then, looks like this:

1) disconnect two keybed ribbons from mainboard (~2.5cm in width)
2) disconnect calibration ribbon from mainboard (~1cm in width)
3) disconnect AT cable from mainboard
4) flip lower chassis over and remove all of the screws in the dual parallel line pattern

The keybed and lower chassis will now be independent from one another and can be separated, either by simply lifting the overturned lower chassis off of the overturned keybed, or by holding the two parts together by hand, flipping them both back over, and then lifting the keybed out of the lower chassis.

Thanx a lot Pablo, much appreciated!
