8 months ago I had a problem with the "level" encoder, the values ​​moved by themselve,problem resolved in warranty service. Now I have the same problem with OSC1 level and OSC 2 level. What will I do when assistance will end?

Buy some servisol spray, much easier and cheaper than sending it off. I am going to make an assumption here that you don't have a cover for your JD-XA, as it sounds like excessive amounts of crud and dust are getting into your encoders - at least throw a cloth over it when you aren't playing ;)
