korg sp-200 digital piano - must take it apart - suggestions?

[viva_zapata74]

hi all,

while bashing away at my korg sp-200 I maybe damaged or dislocated something in the mechanics of the middle C#: now the key springs back up much slower than the others, maybe there's some obstruction, dunno!

thing is: I want to take it apart myself and see if I can fix it, but I never took a digital piano apart before.

Has anyone done that before? Any suggestions, dos and don'ts or, maybe, service manuals?

Any help is greatly appreciated!

thanks in advance, as always

Depends how far will you have to dismantle your ship in order to relieve it from this obstacle. Provided there is one?

Then, will you have to remove the keys and weights from the keybed frame to remove that obstacle? While in the process, if not careful, you can rub the thin layer of oil that resides on the rods and the back of the weights.

So as you progress to your goal, you might end up with more then you hope for. Forgive my alarming notes, but if you have no experience, you might end up, with more reasons to visit the service.

Not familiar with this model, so just took one look to your keyboard. Rather smallish, perhaps, due to portable housing, you wouldn't have much trouble.

If this slow traveling of one key is not result of some physical obstacle. If the problem is actually the felt on the weight "dragging" on the support bar, then a dry teflon spray should be applied to the bar. This is not USER FRIENDLY and requires disassembling the keybed. Believe me when I tell you , not much fun !

If you can open the case, and you can verify that you can actually see this obstacle and verify that you can easily remove the same without any further need to disassemble,… then, you might do this by yourself.

Anything else, particularly if this a new machine - simply not worth of the risk. Particularly if you have no previous experience.

Good luck


P.S. Coincidentally, year ago. I had to remedy some problems with my Peavey DPMC8. New battery, weight checking and overdue maintenance, something I tried to avoid for months. This is the heaviest and most complicated Master Keyboard I ever had "pleasure" dealing with from within

It took straight 16 hours (complete disassemble) from opening to final closing of the DMPC8. Sort of work you either finish, or, if you leave for "later", chances are you will loose patience to go back. No water, no pause, haven't stop until I've seen the first signs of completion.

In that state, couldn't care less to even bother to look for my camera to make a few reminders of this. But, since my GSM was right next to me, I took a couple of photos with onboard camera.

many many thanks for the info and the pics; yo, I had the impression that it wouldn't be a picnic, but as you say, if it doesn't require too much dissassembly I'll give it a shot and if it's something like an obstacle I can see and remove, then it's all ok. Otherwise, well, it's not new but I'll keep it anyway. there's some piano service in town

thanks again
