Techincs SX PC15 Piano

Hi,

I have been using a Techincs PC15 piano for more than a year now but now all of a sudden something went and the key tones seem to be jumbled.
I took it to the nearest music instrument shop, but they are clue less as they are not familiar with Technics, but only with Yamaha.
