Thank you very much for the explanation. You are right not everyone is explaining why they are changing a component. Anyway it is very informative. Thank you.

Hello, maybe you can help me? I really hope so. I have a Yamaha PSR-60 keyboard. It looks like it's fresh from the store and it works like it did the first day. But when the rhythm is running and I hold the keyboard at an angle, the fill in activates as if by magic in a continuous loop. Would you perhaps have a tip for me? Thank you in advance.
