You don't need to reset factory.
You just need to change the setting of LOCAL CONTROL.
Lets start :::
While holding TONE / SETTING button,press key D#7 at 7th octave (highest octave on the right hand). Then release. That's all.
Then the sound must be heard..

Try this
1. Turn off the digital piano
2. While holding down both the (TONE) and (FUNCTION) buttons, press the (POWER) button

Turn the Keyboard off the press and while holding down the [TONE] AND [FUNCTION] buttons power on the keyboard. Wait until all reset is done.

I just fixed mine, it was making the loud sounds and had seemed to have lost the sensitivity. Take out all the screws on the outside, then the sides can come off. That gives access to the inside where you can take out a few more screws (easily seen) and open it all up. The keys themselves just snap in, so two small screwdrivers or strong fingernails can pop them back out. Clean the rubber contacts (they look like little sockets) with Q-tips and rubbing alcohol, then replace the keys. If you take out the white keys of an octave first, then the black keys (keeping them in order) it is a lot easier.

to do a factory reset you Turn the Keyboard off the press and HOLD TONE AND FUNCTION and power the keyboard on while holding them buttons. if you did it right you'll see some wierd start up and flashes and then everything will be back to normal. try a few times if at first it doesn't work. somtimes it's picky.

clean with q-tips and rubbing alcohol around the moving parts, let dry 5 min, and some graphite lubricant may help. graphite is a slippery dry powder good for reducing friction on moving parts. comes in a little tube, normally sold buy the key making dept at any store
