svkr Posted September 15 Share Posted September 15 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 attached 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.

Mike Martin Posted September 19 Share Posted September 19 Raj, The keyboard will need to be diagnosed by a qualified technician with a service manual. More than likely you have a power related issue but possibly a problem with the main CPU board. No one can diagnose this with the information you provided. 1 Quote Link to comment Share on other sites More sharing options...
