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.
headphones plug in but no sound when unplugged means your output ic is working ,so check the headphone socket it may have loose solder or your socket itself may be defected. give it a try it always helped me.
Since plugging something into the Headphone/output port seems to temporarily fix the problem, I would suspect that it might be the power plug of the adapter. Maybe what is happening is that plugging something into the headphone port is somehow putting some pressure and helping the power adapter plug to stay in place and provide power. Odd problem you have there.
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.
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.
Contrary to what's posted above, the Marshall MG series does not pass the speaker power output through the headphone jack, and inserting the headphones into the jack does not disable the speaker. The headphone amp is a separate circuit and it's input is taken before the master volume. So Jan's post is exactly right. Turn off the master volume and turn up all the other gain/volumes as high as they will go. The other issue is that the headphone jack's output does not drive low efficiency headphones well, so you need some headphones similar to Sony's MDR-V700s to hear it well. Earbuds just don't cut it.
