Yamaha PSR EW400 piano intermittently loses sound and shuts down.
Youtube people recommend verifying that the DC jack's solder connections aren't broken, and the replacement of a couple of capacitors in the vicinity of the DC jack. While these solutions might work, I'd feel a lot more secure if I had a schematic to help me check the status of the myriad components.
Schematic and suggestions are welcome.

Re: Yamaha P-115 turn on but No sound - Doesn't turn off
Were you able to get the piano to work? If not, check the capacitors in the vicinity of the 12v input.Leave a comment:
