I have replaced IC 1753 and IC 4580, but every time I press the keyboard keys a tone sounds and a noise sound like sand also sounds, even bigger than the tone sound. The situation is the same as the example in this video.
@@SandyWeldan ic dac and pre amp ic 4558 are very rarely broken. no sound or noise is caused by the 10uf and 22uf condensers on the mainboard being damaged

@@SandyWeldan The problem with all brands of Yamaha keyboards is that it is very rare that the IC is damaged. before changing the ic, first measure all the capacitors on the mainboard. I also experienced the same problem. sounds like sand. after changing the capacitor. the sound is back to normal. 10uf and 22uf capacitors should all be changed
That's why all the capacitors were not replaced. all capacitors need to be replaced. and the IC was also replaced by a digital to analog converter IC and a 4580 pre amp IC
