Question about Casio CS43 Stand for CDP 100

1 Answer

Disfunctioning f note. It plays extremely loudly.

Hi there. I bought my CDP 100 about two weeks ago and the third lowest F is not functioning properly at all. It gets really loud whereas the rest of the keys play normally. It is so annoying and even when i push the key ever so slightly it plays a very loud note. Can I fix it or should i exercise my warrant on it rather?

    I realize this post is almost two years old but I had the same issue. The problem was, as John mentioned, a blob of solder that was shorting two of the key matrix signals on the main board. See picture. It took about 40 minutes total to open the unit, remove the solder bridge and re-assemble it. Good as new (better in my case).

If it is under warranty, may as well make use of it. In the long run it will be less headache for you.

It is something that should be repairable, although time consuming. as it is likely a stray bit of solder lodged where it should not be.

Key B2 playing to loud, not touch responsive


What is your piano brand and type?
Damage to the contact rubber can cause note plays loudly or,
note does not plays at all.
It is caused by:
1. Carbon rubber contacts dirty / dusty (yellow arrow). Clean with a pencil eraser (or cloth). Gently rub it.

2.
Contact rubber is torn (your case). If this happen,it can not be repaired or glue. So, you have to replace one octave.
The yellow arrow indicates the side that is often torn.

Rubber side that is torn, usually not seen, unless we move / pressing gently on top (In the rubber contact position is not installed on the board.)

The third G key on my Yamaha YPT 300 does not cooperate with the touch response feature. Regardless of how hard I press it, it plays the note loudly. All of the other keys are fine.


Below the keyboard, there is a rubber contact (see figure 1).third-g-key-yamaha-ypt-300-not-cooperate-shyexoo0xcste5eq310zs3ot-4-0.jpg Damage to the contact rubber can cause:
- Note plays loudly or

A bought an Yamaha DGX 640 grand a week before and the note sustain for a longer duration and overlaps with the current playing notes. I checked the sustain in the function setting and it is also showing ...


The function setting is for the PANEL sustain (Page 68 of your manual)

The other method of sustain is by footswitch or pedal option. See page 13.

If you use a footswitch, it needs to be a normally open contact type. If you plug a Roland type in, it is opposite polarity and will sustain UNLESS the pedal is pressed. Make sure nothing else is plugged in the sustain jack... headphones that are inadvertently plugged in there would sustain.

Bought amp 1 year ago, three months ago, no sound, Guitar Center said call an authorized repair shop. I did'n't open it up to check fuse because i didn't want to void the warranty. The shop replaced the...


Possible that the output tubes that were replaced are drawing too much current, hence the popping sound (may be "motorboating", one common word to describe a similar sound)

This means the tubes need to be biased properly. You need to get it to someone who knows what they are doing, ie a good amp tech, not GC. The voltages here are dangerous.

I just fixed my CDP 100 which had a similar problem - dropped and two keys not working up one end.
1. Lay keyboard upside down on soft surface. Under keyboard is plastic cover held on by 17 screws. Remove all these and lift cover away. The metal key ends are all revealed.
2. Locate the disloged keys. Carefully press them back into position - they will "click" into place. Make sure the corresponding key on the keyboard isn't stuck in an "up" position - you may have to remove the metal key part and replace it again while making sure the key is correctly seated.
3. Replace cover and screws.
