Kes Posted July 16, 2023 Share Posted July 16, 2023 Hi guys, Does anyone happen to have a service manual for a Privia PX-300? I am after some wiring schematics as it's not turning on. I have an electronics background so would like to fault find the problem. Quote Link to comment Share on other sites More sharing options...
Jokeyman123 Posted July 20, 2023 Share Posted July 20, 2023 The only thing I could find was at this link, but I have no idea whether this is the real deal-and they are charging 10.00 for it. I could not find any other source. https://sbt-servicemanual.com/px-300-ver-2?search=SBTCS2644&description=true I would try some simple voltage circuit tracing-seeing where the voltage stops getting through to the boards, starting with the power supply board-the board inside that connects to the external wall-wart and passes power to everything else. If you are lucky, might be a simple fuse or even a bad solder connection where the power jack connects to the board-these often crack and cause no power to the rest of the boards, although I am not familiar with the this particular Casio.
