Hello,
This is my first posting. My Kurzweil keyboard is starting to have problems. On switching on, the accordian sound button is automatically selected. When I press the grand piano button, which I use the most, the accordian buttons stays on and I have a mixture of piano and accordian for a minute or two ( a disturbing cacophony) then it reverts back to the accordian button, which cannot be switched off. Many other buttons simply do not come on. Is it worth replacing the keyboard? I love the sound of my kurzweil but can't justify the cost of a completely new model of the same quality.
Any comments appreciated

Welcome.

Sounds like the keyboard needs opening up and all contacts and connectors cleaned.

If it is a software glitch then saving user data and reinstalling the operating system could rectify the problem.

Many thanks Biggles. Further question(s)...would it be a dry clean and if not that how does one reinstall an operating system? I don't have a user manual; would that help?

An electrical component company will have a spray can of contact cleaner.

This is on Amazon but I would buy from a specialist shop rather than Amazon.


Have a look at this old thread

Those buttons might be sealed in which case you cant clean them. Contact Kurzweil support for an opinion. (e-mail address removed)
