Damian Gibson Posted May 11, 2022 Share Posted May 11, 2022 Hello I have a Casio WK-3300, and the problem is that after pressing the off button, the screen stays on and without information. As if the current were still passing. This started to happen after I forgot to plug in the transformer all night. Any solution ? Quote Link to comment Share on other sites More sharing options...
Akshansh - Alex Posted August 3, 2022 Share Posted August 3, 2022 Transformer... Did you mean you connected your keyboard directly to the AC mains without connecting to a adapter? I'm sorry. Is your keyboard is working or not? Did you tried to change your adapter of your keyboard? Servicing from Casio Service Center would be the best option to fix that problem. If your keyboard has warranty then you'll be able to repair your keyboard free from any of the Casio service center and the issue will not happen again.
