Thank you very much for suggestions and response. Having not being able to play for the last couple of weeks has forced me into withdrawal so I broke down and bought a Yamaha PSR s750 workstation. I will still actively purse trying to get my KN2000 repaired as it is a great keyboard. I have located a repair technician here in Toronto and I am awaiting his call. I will let you know what the outcome will be ! Thanks again for your response and support!
