Yamaha electric piano loud/dead note key fix YDP-223, Clavinova

Here's how I fixed our well-used Yamaha YDP-223 electric piano. It recently began giving random really loud notes or completely dead notes. The fix involves tearing it down to the rubber buttons and cleaning them well with DeoxIT Fader Lube (Amazon link below). It's good as new now!! -- https://amzn.to/3CdLYEO (Amazon: DeoxIT Fader Lube) As an Amazon Associate I earn from qualifying purchases. So please use the link above if you decide to purchase anything!
