Bob... with keys not working on a CT-S100

[badbob]

On my cts 100 casio various keys don't work.

There seems to be a pattern of faulty keys.  I therefore assume its unlikely to be dirty connections on those keys.

 

The attached image shows the faulty keys.

 

Can anyone suggest a fix?

 

Thanks

Hmm, I don't see an image.

I can't see a way to add an image except for a url

Maybe you could mention the notes of which the keys do not work?

I don’t know Casio keyboards, but in general the keys of a keyboard (this also applies to computer typing keyboard) are wired as a matrix, meaning that one broken connection/connector results in several keys going dead.

I'm assuming the black keys with the dots on them are the ones in question.   Unfortunately that's not something a misconfigured setting on the keyboard would be responsible for.  It's more likely a hardware issue in the circuitry, something a technician would need to look at.

Black keys and white keys have dots.

 

I wondered if it could be one of the connectors.  Are there any circuit diagrams available?

[Brad Saucier]

Unfortunately none that I'm aware of.

Now fixed.  Cause was a connector inside  not making a complete contact.

 

Thanks for all the comments.
