Thank you so much for your response and info, Ted !

Opened the k-board myself and, tightened/and fastened some long ribbon cables with a few ty-raps, ...

the keyboard is working : FINE !!!

Also it looks a whole lot better inside(haha), put it back together, and played it for an hour!

Very happy again with the WK7600 !

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 ??
