***Casio WK 3000 keyboard

If switched off (yes via the power reset button rather than pulling the power plug), left some time and then powered up. It plays dumb, display echos the key presses and midi functions normally but no sound out of the built in speakers unless you wake it up going into demo mode for a bit. Nothing wrong with mute/standby functions of the main amp. No flash memory card used with it but are there switch contacts in the card slot that should be open or closed and falsely registering a card is in the slot?

There might be a micro reset sequence which will get everything back to factory settings, you need to search the interweb thing

I downloaded the 150 page user manual possibly on powering down "local off" setting for midi use is stored in the memory. Seems no access via the keybpoard/keypad/buttons etc to alter this, must be via an external pc/midi link. But just pressing "piano setting" resets a number of things , one of which is setting local to ON (if OFF), in the troubleshooting guide , if you have a silent keyboard.

This Keyboard not used via MIDI But there must be some powerdown (or power up ) fault creating this random occurance (left unpowered overnight and powered up perfectly ok, despite deliberately switching off at the mains rather than powering down via the power on/off button). No obvious on-board battery , although overlay symbol and unpopulted section of the main board has this for some other model type.
