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.

To start with try a master reset, whilst the instrument is off press and hold the top (highest) sounding key whilst turning on.
When the screen displays Yamaha release the top key.
If this doesn't solve the issue then it could be a number of things as the keyboard does a self check on startup and will hang if a fault is found. Check each rubber switch is not stuck down or even missing this can cause this issue. Please report back either way.

Try cleaning the headphone jack. If that doesn't help, it'll be the amplifier board and will need to go to the shop.

Dead keys on Yamaha PSR e413 keyboard: Flip keyboard upside down, remove cover screws (use marked cardboard template to remember where they came out), spray suspect key-contacts with fast-drying contact cleaner, (usually a PCB with a matrix of contacts under keys), re-assemble base cover, wiggle faulty keys as far as possible to 'scrub' any dirt or oxidization. If this cleaning trick doesn't work, get a pro to check it.

Hi, i think you can. You can go to any of the Yamaha companies around you area and explain to them the problem of the keyboard. They will give you good and quality replacement part for your Keyboard.

Make sure you go to only Yamaha company to avoid getting a wrong part for your Keyboard.Avoid road siderepairsforissue like this,it's more complicated to handle

I guess that will do.
