Buttons not working anymore...

curvebender · Post by **curvebender** » Tue Dec 01, 2009 8:48 am

I am experiencing problems with my two up and down-buttons on the oasys. They don't react well anymore, and I sometimes have to press really hard to get them to work. (Sometimes they increase or decrease two steps instead of one.)

I'm guessing this is due to dust/dirt build-up on the contacts.

Anyway, is there a way I can fix this myself? Is there some sort of air spray I could use?

Or do I have to open the lid and try to expose the contacts and start cleaning from there?

I'd hate to have to take my Oasys to my dealer, it's such a pain to transport it!!

Thanks.

yes first thing to try would be to get a can or air and spray under the buttons . Most decent computer or electronics shops stock that. Let us know if that works, or else Korg might have a better idea.

Cheers

I just got myself a can of air spray, and I'll try it soon. (I'm curious if it will have an effect, since I can't get under the buttons...)

Anyway, I'll let you know.

Too bad it didn't work...

I opened the lid, and managed to get the nozzle of the spray just above the contact area. I sprayed a few times, but nothing...

Any ideas?

Sounds like the tactile switch is dead.
I'm not sure if the ones in the OASYS are the same as the Trition Series, but this link might be a good place to source parts when you find out exactly what it is you need.

Here's an example of how to replace them on an X3

Sharp,

Thanks for your reply.

I will look into it.

Curvebender,

I am experiencing problems with my two up and down-buttons on the oasys. They don't react well anymore, and I sometimes have to press really hard to get them to work. (Sometimes they increase or decrease two steps instead of one.)

I have exactly the same problem. This problem happens to me about 3 weeks ago and day by day it's always worse.
Did you inform your dealer?
Could you please keep me informed how you solve this problem?

Thank you
Drunky

I've contacted my dealer, and I am waiting for them to reply.

My main concern is having to transport my Oasys to the dealer, and then they have to transport it to the service center and back and so on...

I've asked them if it's possible to have a technician come to my house instead.

I'm not that worried about the buttons, since I am convinced it's an easy thing to repair if you have the right skills and the right tools. (I have neither!!)

Putting something high pressure under the buttons is not always the best idea. If there is dust contamination then you may move the dust elsewhere in the keyboard, even under a key contact causing something else to not respond.

The most likely cause is, as has been said here, the tact switches. Repeated pressings over the years wear out the contact or even buckle the legs that the contact uses to sit on the surface underneath.

You should have it checked by an authourised service centre who can do the work for you.

Mike,

I am going to have it checked by authorised service, of course. It's more a question of logistics really.

But I am somewhat irritated that the buttons cave in so fast! This is a premium $$$ instrument, and I didn't expect this to happen after one year of using it relatively modestly. (I've owned it for 2 years, but the button problem surfaced a year ago.)

Oops..I stand corrected..again.

You are correct that sometimes an air duster does move the dust to somewhere else, but I just figured it was worth a quick try before having to then turn to the much more intensive effort of arranging to have the keyobard sent to Korg and so on. Surely a quick squirt of air would be worth a try at least and no worse than the present predicament of poor old curvebender.

But I guess using an air duster is not always the right solution, so sorry for that.

Cheers

Tangent,

Don't worry about it! The air spray was my idea, it was worth a shot.

On the bright side: I was happy to discover that there almost wasn't any dust at all inside my Oasys! Clean room and always using a cover when not playing.

Yesterday night I spent few hours to open the lid and check inside the condition of my keyboard. I keep my O in a clean room in my home studio. Without dust and without humidity.
And inside was more cleaned then what I was expecting. Everything was good (that's is my impression) so I decide to close the lid and wait for the answer of my local dealer.
After this short check up switching on my O everything was exactly has it was before and no improvement.

I will keep you informed about the answer I will get from my distributor.

I am also interested in the result, 'cause I have the same problem. Two buttons (PROGRAM and UP) sometimes are working only when pressed VERY hard. Yes, they are used more often than other buttons, but the instrument is not old, still in excellent condition, and I'm using it with love and care. (And I have experience with many cheaper instruments without such problems after long years of intensive usage.)

I'm not sure if the problem is with the small part itself in the circuit board, or just some deformation (?) of the plastic button over it.

If I cannot get a replacement, I maybe will exchange the bad ones with rarely/unused ones, like FUNCTION or a USER BANK button.

I had the same problem with value up button.
The problem has been solved by spraying a dry contact cleaner directly on the switch (the little black button soldered to the big electronic board)
To do this I had to "dismantle" the left side of the Oasys lid.
Now everything works again as it should, but........

- I know the remedy is a temporary solution. In fact other users experienced the same failure
- I took everything off because I was not sure I would be able to spray directly on the switch, using the little pipe which the spray can comes with.
After I understood I would be able to do that.......I did it just to have a try. Doing this means that a little quantity of the sprayed solution also affects the plastic pushbutton (which is attached to the lid by a double face adhesive tape). What happens is that the plastic the button is made of, revealed to be poorly resistant to the spray solution, so now the button is duller than all other buttons of the panel.
This is very strange, I never had any kind of problem with that spray.
I already asked for a spare part to the official italian dealer, but I am still waiting for an answer
