Try a master reset to start with. Turn keyboard off Turn on whilst holding down highest note on keyboard Once screen display has complete release key This will reset to factory settings. If this doesn't work report back and we can maybe try other solutions. Dan Becketts Music Ltd

if you have a technique you may have to untie it and fix the keys.check any guest things on the keys.

Yamaha is proprietary and you will not be able to locate one. You have to get Yamaha to service it.

The correct part is V2115000 https://beckettsmusic.co.uk/products/v2115000 I hope this helps

All programmable keyboards have internal batteries to save memory programs.

Not sure about the serial #... but 'C' clarinets are not common.
They are slightly shorter (2" perhaps? ) than the far more common Bb clarinet.

first, how old is this unit? according to this page https://en.wikipedia.org/wiki/List_of_Yamaha_products#Electone_(electronic_organs) they were built between 1983-1988. In other words, it's over 30 yrs old and it may have had some internal electronics finally die. https://www.manualslib.com/manual/779640/Yamaha-Electone-Fs-30.html https://www.manualslib.com/manual/779640/Yamaha-Electone-Fs-30.html?page=29#manual

Does it ever turn off? The PSRE313 uses a rubber on/off switch with a carbon dot on the underside that does wear out. If all is working well I would suggest replacing this rubber switch part number WD893400

maybe this will help ...... I have a Korg M1 ..... it has a small button battery for maintaining memory and sounds .... mine lasted about 10 years ...... I looked up in Google how to change the battery .... I looked up in my M1 instructions how to reload the sounds .... I had lost all my synth sounds except the basic piano ...... I changed the battery and reloaded the sounds from a backup card I had bought years ago .... M1 works perfectly now .... you probably lost any saved songs .... contact Yamaha how to change the battery and reload the original songs .... any saved songs are gone .... next time, back them up ... good luck

Try MIDI

With RCA cabling.

Yes, an aux jack is looking for a powered input. An electric guitar is just a passive input, like a microphone. If you're interested, a solution and a great upgrade would be to get a wireless guitar input (battery powered). The wireless receiver would likely have an RCA output that would work with your receiver. Solves your preamp problem and you have a wireless guitar.

We live in the 21st century, just google it.

This might sound obvious but first of all I would try an older smaller flashdrive. Some large versions are not supported by certain keyboard. Try a simple midi file or similar with a smaller drive, if that works then it could either a procedural error in the way you are completing the task or that the larger drive is not supported. Did the drive in question previously work? What size drive are you using? What are you trying to do? Save work, update software? Good luck Becketts Music Ltd
