CASIO CTX-870IN issue

Dear forum members,

Having an issue with my Casio CTX-870IN keyboard.
After I power ON the keyboard, the display is ON, but it always shows like the picture. Keyboard does not react to any key presses. The display is frozen and the keyboard is practically dead.

Can you please help me troubleshoot the issue.

Thanks in advance.
Regards,
Raj.

(Please refer to the attached image of the frozen display after Power ON)

look up factory reset, replace the batteries with new, plug in ac adapter.

follow the trouble shooting guide.

failing that, something else is wrong and requires a tech to solve. you can ask at your local music store if there are any techs in your area.

Thank you, midnightvisions !
Troubleshooting guide could not help. Display is just stuck like shown above after power ON. Thank you for sending the user manual.

Can anyone kindly send me the SERVICE MANUAL for CT-X810IN keyboard, please?
