Hi, We are so new to keyboards. We recently signed my son up for lessons, and purchased our first keyboard ever the CGP 700. We used it yesterday came back today, and now the speakers have no sound. We did a reset 3x, unplugged everything, walked away came back did it again. Did all required stuff on the owners manual. We plugged in headphones and we have sound. Not sure what is wrong. Any tips or tricks? Thanks in advance.
