I do not believe that a setting is causing he problem. (In my limited Knowledge)

1-The keys will not make the style do chord changes.

2-I did get some sound a few times when I pressed the keys, but it faded after a few seconds. An on and off setting would not react that way.

3-I did get sound for a very short period when I move the cover. That only happened once for a very short time.
Now to find a Technion that will handle the problem.

Nigel, Gunnar, thank you for helping, John C.

John is it possible being its an older unit that the key strip contacts have worn out causing the problem?

If it were the contact strip I doubt they would all wear out at once. I had the keyboard stop responding with a instrument. I opened it up and reseated the cables that went to and from the keyboard and the motherboard. That fixed it for me. This could be a easy fix if you are comfortable taking the instrument apart. If not, then definitely find someone to service it. Wishing you the best of luck on the repair.

Have you midied the KN7000 with another keyboard to see if it responds and plays normal. If it does that further isolates the problem as being the keybed.

John, I agree with Solomon8's suggestion re: "reseating the cables."
"Reseating the cables" has resolved a lot of my keyboard malfunctions.
As mentioned...it's just a case of getting to the cables that might be a mini challenge for the KN7000.
I have lived in Florida now for 42 years.. and I think we here in the humid climate [Florida] are even more prone to oxidization issues on cable contacts/connections.

Thanks to all for your help.
Have tried everything that was recommended, to no avail.
When I load a sequence it plays without error. BUT when I try to use the outside controls, the controls when the lid is closed I get this reading; ERROR #83

The error messages I have in the manual and service manual only go up to #73or #71. Any thoughts on Error #83?

John..dealing with a discontinued model unit can be a daunting situation when service is needed and no where to turn by the manufacturer. I hope you find a solution...worse, trying to sell an older unit that has a problem is even harder...

good luck

John....
I haven't needed a tech in years...but when I did, I used John Kasche in Royal Palm Beach. Last time I saw him he was training a guy to take over his business. He wasn't cheap, but he always came through for me.
