My Yamaha psr 413 has a bad connection when I try using the ac adapter to power it. Is this something I can fix myself, or should I seek professional repair.
I believe your keyboard may have been originally supplied with a PA 3C Power Adaptor. Yamaha has replaced it by the PA 130. Unless you are adept at repair work and have the tools to attempt any repair, I suggest you check Ebay’s prices for a new one, then check for cost of professional repair so you can make a smart decision.
