I send my WK7600 for service to my local dealer, after a few weeks of use.The problem was that on nearly all the keys the B and the Dsharp were not working/no sound, even after initializing it for several times.
When I got it back they said that they couldn't find anything wrong, ....I thought...strange, ...but I was happy because it worked fine again!
I havent used it for a period of time, so my warranty expired, but when I turned it on, last week the same problem was there.
I've tried initializing again, wich didn't work, so I can't use it at all!
My question is: Maybe this problem, probably a Software problem, is known by someone .... any suggestions ??
