I want to apologize. You and some of the others here are getting your info from places like Urban Dictionary and I finally put 2 and 2 together. It’s not that you don’t understand that the Yamaha parts are fine, it’s just that you are uninformed and don’t know any better. You believe anything you read.....a few say it’s bad so the part is bad, again it’s just you don’t know any better. I’m sorry the system failed you, maybe one day you will figure it out but it’s pretty clear you can’t.....sorry.
