I can no longer turn off my Casio CT-X5000 using the power off button. I can only turning it off when I unplug the keyboard. In the switch-off position, I put the plug in the keyboard again, and I can switch the keyboard on again via the normal switch on button on the keyboard. Unfortunately, the LCD screen does not display the normal factory default settings. I try in vain to restore these default settings via the function button, but this button also no longer responds. In fact, all buttons on the keyboard no longer respond, except the jog wheel. Does anyone know how to restore all this to the position as I bought it new. Thanks in advance for any help 🙏🙂
