Hello to all the experts, I have an electric piano 3500 KR and in the lowest octave, it makes a not sharp sound. Whereas in the high octaves it makes a sound like that of an echo. Have you encountered such a phenomenon? Is it because there’s a button pressed somewhere? I got the piano so I do not know its functions. Are there any capacitors that need replacing, if so what do you think, or something else thank you very much
Hi @electri , I don’t know the piano but have to tried resetting it back to factory default? Here’s the procedure: While holding LOAD and SAVE, press WRITE Here’s the user manual if you haven’t already got one. Also found the service manual if it is necessary to do any testing on the boards etc. The downside is that you have pay for it. Hopefully a start.
