SOURCE: I have a Casio Privia PX-320. The left side keys

Check that the front of the keys is not hitting the lower plastic case front. If they hit it, then you need to disassemble the case partly and see what has shifted. It is ALSO possible that something has caaaused the aftertouch sensor to move out of position and it is hitting the keys early. ANY of these conditions needs to be addressed before damage is done.

SOURCE: Casio Privia PX-800: When using the sustain

Check if the cble frm the pedal MIGHT be flexing or pulling on the keyboard case when you use it. Such movement COULD vibrate the power connector causing your problem.

Make sure you have the right power supply for the unit as one with too large a hole for the power pin would be intermittent like this.

SOURCE: Casio Privia PX-130, 8 months old: fluttering sound

If I were to venture an educated guess I would vote for failing filter caps in the power supply.

The power is likely collapsing under load of the speakers but headphones take much less drive.

If this has an external wall-wart power supply, you might try a new one IF the output is found to be under the rated voltage.

Internal power supply components are beyond those individuals that are not adept at electronics.

Casio privia px-110 the volume pot dosen't work i can't make the sound higher or lower it seems to be fixed at one level


That sounds like the volume pot has failed and needs to be replaced. I'd suggest taking it to a Casio service center. Here is a link to find one-

I have a Piano from Casio Named The PX830 BP.I also have a Sustain Pedal Model from Casio named the SP 33.Will connecting the SP 33 into the PX830 BP work?Please tell me if I have the wrong model.


Unfortunately, the SP33 pedal will not work with the PX-830BP. Casio lists that the SP33 will only work with the PX-150BK, PX-150WE, PX-160BK, PX-160GD, PX-350BK, PX-350WE, PX- 360, and PX-560 keyboards.

The PX-830 manual does not list the stand or the pedal unit as separate items if you need to replace them. The pedal unit has 3 pedals like a traditional piano. I wish that I had better news for you.

How do you adjust casio px 300 when connected to ipad2


Newer Casio models that have "class compliant" USB interfaces such as the PX-330 would work (plug and play) since they now have "class compliant" drivers.
Unfortunately PX-300 is an older model that would need specific drivers and Casio only made drivers for Windows PCs.

How do you connect a casio privia px 330 usb to ipad 2


Casio don't supply PX330 drivers for IPAD.
Get a Windows 8.1 tablet or connect PX330 to a desktop PC and use IPAD to Remote control that PC.

Where is the midi connection on the casio px 700


At the bottom near the power jack.
You may need a Midi-to-USB "cable adapter" to connect to a computer.
