I have a BASE mk-939 61 Key Music Keyboard – It does nothing.

OK so I turned my music keyboard on for the first time in about 7 months because i've never used it before and it turns on but does NOT react to me pressing any keys.

Even the volume won't come on, nothing works basically the only thing it does is turn on.
