Question about Casio Music

Open Question

The damper pedal on my Casio Privia 860 makes a clicking noise when depressed/released. I cleaned the mechanisms that I can reach with alcohol, and blew them with high-pressure air, to no avail.

SOURCE: unable to depress the brake pedal

your power brake booster has failed, or the large vacuum line to it under the hood has come undone.

SOURCE: casio privia key issue

The only way to analyze this is to open the case. You may find contaminating material has gotten in, or broken part, or key slightly out of position on pivots or pivot plastic broken.

When opening, be VERY careful of the tender ribbon cables. Have a large work surface that you can unfold the top onto. Be careful to use correct screw lengths and thread in each place you removed.

    What is causing noises in my Casio privia Digital piano?

    Pivots worn out or need lubricant. Make a warranty claim first.Otherwise, If out of warranty I would try to lubricate the hammer pivots myself. You will need "grease suitable for plastics".

    Casio Privia 410r Piano soft pedal problem

    The Casio Privia 410r has two pedal jacks at the back. One is the sustain pedal, the other is the soft/sus jack. Please use the other jack if you want to use sustain pedal. Only 1 of the 2 jacks can be used.

    However, if you have the optional sp30a pedal which plugs UNDER the piano instead, then only can you have 3 different piano pedals.

    My casio privia px830 pedal doesn't sustain enough,

    It could be that the electronics of the pedal are dirty, or that dirt has collected under it causing it to not depress all the way. Try taking it apart and cleaning it with a Q-tip and rubbing alcohol. Be very careful of any wires or delicate articles.

    I Have a Casio Privia Digital Piano and a Roland DP-10 pedal. The pedal function is inverted. When I press it stops the sustain and the effect comes back when I release the pedal. The pedal does not have...

    Yep... Roland pedals are reversed, that is, normally closed contacts. Unlike some Yamaha keyboards, the Casio doesn't have an inversion function available. You have two choices to solve this: 1. Buy a pedal with the corect sense 2. Open the Roland pedal and MAYBE with a soldering iron you can move a wire to select a contact with the opposite sense.

    I've recently purchased a Roland foot pedal for my casio privia px-300 keyboard. When playing a note, even though the pedal is not pressed, the note sustains. When I press the foot pedal down, it cuts...

    Sorry, but Roland uses the opposite sense switch. They use normally closed where Casio requires normally open contacts. SOMETIMES one can rewire the pedal internally, but you have to be mechanically and electrically inclined to do that.

    My Casio Px 330 keyboard is about 1.5 years old. After the instrument has been played for 20 minutes or so, one note (D above middle C) sounds very loud regardless of how hard it is struck. The problem...

    This is a problem with one of the two contacts for that key. The contacts close at different times as the key is depressed and the time it takes between is measured as velocity which is used to control the loudness as in a regular piano. The contacts are conductive rubber pills. After a lot of dis-assembly you can clean them with 99% isoprphyl alcohol and Q Tips. Clean both the pills and the circuit traces on the board they are pressed against. Be very careful of the ribbon cables between the halves of the case.

    Hi, the sustain pedal on my Casio PX-830 has a constant squeak now after 6 months, any ideas on a fix for this? Thanks.

    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

    The inlet jack for a damper pedal is not working, how can i get to it to see the problem?

    Before opening the unit VERIFY that your pedal is working with an ohmmeter. Pedals and the cables often fail. Often people try to use a pedal not intended for this synth and they find the pedal inoperative.
