Headphone jack is too big for my headphones

IKf you are meaning the speakers don't work when the headphones are pkuged it, that's the way it's supposed to work. If you are meaning the after you plug in the headphones and then unplug them the speakers still don't work, that means you either have a dirty headphone jack or the jack itself is broken.

First, re-initalize the piano. The instructions are in your manual or on the manufacturer's website. If that doesn't do it, try the headphone out. If the headphone works but the speakers don't it can just be a dirty jack. However, if none of this works the amplifier board is probably blown and you'll need a repairman.

It sounds like you are in need of a new piano. These are common issues with keyboards. The age is a big factor. It would cost just as much in repairs as it would to buy a new keyboard.

Jeremy hi
you must open the piano and change the headphone jack

Some keyboards use the amp output sockets for headphone use.
You might need some adapters for your headphones.
If it fell in, you would see an empty hole. This would be unlikely because it is held on by two screws. If all fails, buy an amp with a headphone jack input. Plug the keyboard into the amp and use the amps jack.

I first would suspect the switches on the eadphone jack. Normally these cut off the speakers when headphones are plugged in. These jacks and the switches are really weak, poorly made, and easily broken, especially if headphone cord gets yanked.

What type of headphone connector do you have? The Yamaha keyboard headphone jack is a 3.5 mm stereo jack (like on a computer headphone jack). So if the headphones have a 1/4" plug, you need a 1/4" to 3.5 mm adapter.

I hope this helps.

See if the sound is present at the headphone jack by plugging in headphones. This is the start of testing.

The keyboard has a mic jack that is the same size as the headphones. You probably put the headphone plug into the wrong jack is all.

It might be that the contacts for the headphone jack is very dirty. Try using a cotton swab with a wd-40 on it to clean the inside contacts on the jack.
