Casio PX-330 _ sound weird

[khoaofgod]

I bough Casio PX 330.

When I play the "A" note , or "B" note, I heard weird sound come from speaker .. It's small electric sound.. Like "teererererre"...

When I plug the headphone in, sound is perfect.

Can It be fix ? Or the bult-in speaker can not handle maximum mhz ?

When you back off the volume does the sound go away ? If so you may need an external speaker setup that can take more watts. There ar emany causes though but in the audio system someplace not in the notes themselves , since the odd sound goes away with head phones. My guess is will when hooked to an external system as well ( not sure of the hook up on a PX 330 off hand, hope it's a decent 1/4" or something similar)..

The sound not go away 100%, but I can't heard it when I turn volumn down to 50%.
That sound is small, audien can't heard it, but Its really anoying.

I plug the 3.5mm stereo cable to my Sound Bar 120 watt, and the sound anoying at "C" note ... Lmao.

I am waiting the cable 1/4 shipped from Amazon to test 1 more time.

Thank you for contacting Casio America. I am sorry to hear that you are
experiencing a problem with your PX-330 digital piano. Check the
speakers to see if there is any debris making contact, which you can
remove. The speakers vibrate when they produce a sound. If foreign
material is in contact with a speaker, then it may also be vibrating
and/or affecting the speaker's vibration.

Also, try resetting the piano. To do this, turn off the piano, then hold
down the TONE and FUNCTION buttons as you press the POWER button to turn
on power.

If the problem persists, then the piano would require repair. You can
contact one of the Authorized Service Centers for musical instruments
listed at https://www.casio.com/support/musicservicecenters if repair is
needed.
