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.
@@vantergames9214 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

@@vantergames9214 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
I have a Korg PA 300 . Problem- I played keyboard for the first time. But suddenly the keyboard shut off after this it can't be shown. What is the reason?

I need to repair or replace the right ribbon. When pressed, the sound or effect remains active and it is because a key on a pedestal left it sunk in an accidental blow. I thank you in advance for your guidance!
Bom dia , tenho uma HPD15 que comprei recentemente, porem a função DBEAM não funciona , o Led Sound não acende, e os 2 últimos peds pequenos à direita acionam juntos. Já troquei todos os cabos flats, limpei todos os conectores, os 2 leds infravermelhos, mas não resolveu... Tem ideia do que seja, ou qual circuito integrado ou componente esteja causando esse defeito ? Desde já agradeço !
