If the port is still intact then it might just need to be resoldered. USB ports however to get strained and basically fall apart. Purchase another and solder it to the board. If you are not confident about doing this take it to your local Yamaha service centre.

Most likely it is not worth it fixing it. You can probably get a new model with more features for about the same price of fixing this one. Let it go anf upgrade. That is the reality of electronics and technology.

The style files are probably NOT compatible between the units even though the name header of the file displays on the e403.

Sorry to bring the bad news but the PSR300 does NOT have a connection for a sustain pedal.

It will however recognize a MIDI command for sustain so if you had a MIDI sustain pedal that emitted controller 64 code, you could use that.

It is UNLIKELY you would want to do this as such devices are not readily availablle. If you slaved this from another synth that had a sustain pedla capabilty you could play booth together and use the sustain of the other synth.

Wild guess of possibilities.

1. Internal backup battery exhausted.

2. Button OR key is stuck down, either mechanically or electrically.

1200 ma provides more power than the 700 ma, and would not be affected by using it on a device that draws 700 ma. The voltage of the charger makes a difference as well as the polarity of the plug. (if it is dc)

If the 700 ma charger is not working, most likely the 700 ma charger is not working

try placing your ear on the speakers, adjust the volume control up and down several times, you should hear a humming sound that goes up and down. if not problem with the stage before the amplifier, that is the sound processor. if you dont hear the hum. problem with the amplifier and speakers, including the sound ports or jack. dissassemble the unit. look for loose connections from speakers to amplifier.

An answer, but likely not a solution. I believe all Yamaha PSR series keyboards use the same 12 VDC adaptor, so I looked at the electrical schematic for another model I have. There seems to be no fuse on the power input. There are two components shown on the positive and negative wires off the power socket, but the symbols do not look like anything I have seen for fuses - they may be resistors. Power goes directly to a 5 VDC voltage regulator, which powers all of the solid state componenents. Too much voltage of the wrong type could have easily ruined many of the sensitive components.

Your only hope is to check the power socket area for the possibility of having fuses. My drawing shows the power socket, voltage regulator, and audio power amplifier being on one circuit board. That may not actually be the way it is in your model.

Good luck!
