Son of Yoda
I don't play much keys but occasionally add them to a tune, so I pulled out my Roland Juno D only to find there's a key no longer working.

Naturally, it's middle C!

So I got around it by moving pitches by an octave, given I'm playing single note stuff in the main... no probls...

But how does one repair a dead key? While it's several years old, it's not been played all that much.

Any clues?
 
Yup ... more than likely it's a dirty contact.
Had my share of fixing them too!
Real caa caa poo

You have to take the keyboard apart and remove the key that isn't sounding (don't lose the spring) lift the rubber/silicon pad that the key strikes and clean the contact with a Q-tip.

Oh joy.... you know, I've got about 10 pieces of gear now that have some minor thing wrong with them and I never seem to get around to fixing them... I should just load the car up and drop them off somewhere and "have a man do it"...

OK with pulling guitars apart, never tried a keyboard.... could be a learning experience...

They make self cleaning ovens and self defrosting fridges, can a self cleaning synth be too hard to build?

Cheers Henry...

You know the first one I ever did only took an hour or so just take your time and everything is self explanatory.
Flip it upside down and take out all of the screws that hold the bottom and top together, then slowly turn it over and even more cautiously lift the top off, front to back. There maybe some ribbon wires that you don't want to disrupt.

Then you'll see how all of the keys fit into their spots. Push down on the bad key until the hooks are free and it will come right out -- DON"T LOSE THE SPRING -- it's on the bottom.
Then you can lift the pad and clean the contact.

It's amazing how dirty they get - looks like some body poured a mixed drink in there!

Then reassemble.

Now your a pro!
 
Thanks Henry.... it's dropped down my list of priorities! See my rant in the "I can't get my damn PC working properly" forum. Perhaps I should just stop stuffing around with Windows and pick up a screwdriver, I can probably do that OK...

Cheers
 
You're right Henry, it does take about an hour to disassemble a keyboard and stick it back together again. A few extra spring washers at the end of it but all 45 screws went back into the right holes, even when I had to pull out circuit boards after dropping one!

Alas, however, it appears the contacts are a sealed system. There's nothing to clean there, and besides, it was clean as a whistle in there. I'd hardly played the thing....

So, still dead. Roland are on my shit list now. It's such a PITA to get stuff to them here in Sydney too as they're on the other side of town completely..\\

Thanks anyway!:)
 
The contact didn't have a rubber type cap over it that was able to be lifted/peeled up? :confused:
 
It did, but it wasn't able to be peeled up as it was joined to about the next octave and a half, and glued down and completely sealed. Nothing's got in there...
