Random Buttons Cease to Function! Repair? PSS-170
(Highland, UT, USA)
All the keys work great. This is a classic keyboard, but some of the coolest buttons just stopped working randomly.. all at the same time: Tempo-Up, Demonstration Start/Stop (Billy Joel and his awesome song, "Don't Go Changing", Fill In, and Vibrato. This breaks my hear, because I love to use all of these buttons. I'm no electrician, but I'm not afraid to try. Is that the problem, and if it is, should I try to fix this?
Thank you so much for you help!
