My GP 510 has stopped working today unexpectedly - I've been happily playing it for a few years with no issues. I've tried to turn it on but the 'Welcome' message jusr stays on the screen and all button remain with their red LED on and does not load the default piano and allow me to play. I have turned it on/off at the plug socket that doesn't seem to work. Any ideas? Michael.
