Yamaha PSR 550 keyboard – Disk Mode Limitations
by Chris

I have a Yamaha psr 550 keyboard and it seems to be behaving erratically at times. At times it does not respond to any of the buttons that I press, nothing seems to happen or function, even when pressing any of the panel buttons on my psr550.
For instance, pressing the DEMO button on my PSR-550 does not start any of the Demo songs, the buttons to select the voices and styles seem to be disabled, even playing the keyboard does not produce any sound.
Is there any problem with my Yamaha PSR 550 keyboard?
