berry14 Posted June 25, 2023 Share Posted June 25, 2023 Hi all, I've got a Casio WK 6600 and it used to work fine. However, today when I pressed the Power button the display screen only lit up momentarily, nothing is shown on the screen, and if I keep holding the Power button the display would be on for maximum 2 seconds before it starting to "fading" or slowly turning off. I tried changing to another power outlet, tried holding the E.Piano and Bass buttons while pressing the Power button, but nothing works. It has never been like this before. What should I do?
