Hi to all !!! My name is Guillermo and I'm from Argentina. I was glad to recieve as a gift a Roland Piano model RK-570. The problem now is that I cannot ise it because of it's anoying noise/interference. It is very clean inside. Here you can see a very short video showing the noise. I also attach a picture showing 3 capacitors. I do not know if the white product is glue or if they are damaged. Thanks!
