Hi

I cannot find a service manual for your keyboard but perhaps the link below may be of some help.

Usually there is a problem with the connections or cable between the control board and the keyboard “boards”. Depending on which notes are affected determines which connector/cable/ board needs to be looked at.

Hopefully this is of some help.
