No Piano Sound, Also Usb Emulator Doesn't Work.

I have a Yamaha PSR-740 in need of repair and possible 'upgrade'. It was damaged by movers last year, the piano makes no sound through the speakers but the demo does play.Also, I installed a USB emulator drive to replace the old floppy disc drive that doesn't seem to be reading.
