Why does the piano sometimes have no sound when some keys are pressed?

I guess I'm going to find someone to tune it up.

Summary. Hello dear, I'm glad to answer your question, there is a key in the electronic organ that has no sound can be solved by the following methods:1

If there is rust, then gently remove the rust spot with a flathead screw at the rust spot.

Dear, hello, I'm glad to answer your question, there is a key in the electronic organ that has no sound can be solved by the following methods:1If there is any looseness, the skin beam needs to be reconnected and fixed, if there is rust, then gently remove the rust with a flat-head screw in the rust spot.

2.If the dust is placed for a long time, it is likely that the circuit crack belt board is not loud due to too much dust, and you only need to disassemble it and wipe the circuit board lightly with a cotton ball dipped in alcohol, and then install it and close it.

3.The reason for the conductive glue is that the conductive rubber inside the electronic organ is easy to age, check whether there is a pure width defect damaged, if there is damage, it is recommended to replace the whole strip. If you understand circuit knowledge, you can buy conductive adhesive to replace and repair it yourself, otherwise Qiaoji can only find professionals for debate.

The piano has a key and no sound, dear! Hello, I'm glad to answer for you<> pro-piano has a key and no sound, the solution is 1, lack of strings, the strings of the piano are broken, there is no string vibration sound, and the strings can not be played naturally. Workaround:

Replace the strings of the same model. (Need to have piano tuning lawyer skills) 2, the action machine failure is delayed, in the external key pressed, the end of the key is raised to push the action to transmit the power to the hammer, if the action rod is broken, not reset, the screw is too loose, etc., the process of transmitting power is blocked, unable to push the hammer, will also cause the key to laugh. Workaround:

Mock inspection and finishing of the action. (Piano tuning skills required) I hope mine can help you <>

Do you have any other questions?

Hello, the electric piano suddenly has no sound for each key and the reason and how to deal with it 1, the connection line problem to check whether the connection head is normal, whether there is loose, but also to see if there is rust on the circuit board, if there is loose, you need to re-connect and fix, if there is rust, then gently remove the rust spot with a flathead screw at the rust spot. 2. If the dust is placed for a long time, it is likely that the circuit board is not loud due to too much dust, so you only need to gently wipe the circuit board with a cotton ball dipped in alcohol after disassembly, and then install it. 3. The reason for the conductive glue is that the conductive rubber inside the electronic organ is easy to beat, check if there is any damage, if there is damage, it is recommended to replace the whole strip.

If you understand circuit knowledge, you can buy conductive adhesive to replace and repair it yourself, otherwise you can only find a professional. 2. What are the keys on the electronic keyboard 1. Starting from the leftmost key of the large character group, the white keys are C, D, E, such as branch F, G, A, B, and Bai corresponds to C in the key. 2. Comparison table of electronic piano sound area:

There are 36 white keys and 25 black keys. 1=a, that is, the A key, with the A key can play the sound of 1, and the black and white keys on the slag hand sensitive electronic organ are divided according to the twelve equal laws. There are many reasons why the keys of the electronic organ do not sound.

For example, there is dust or moisture inside the electronic keyboard, and the circuit board under the keys is not in good contact (there is a contact point under each key), if you know the circuit knowledge, you can check and repair it yourself, otherwise it is recommended to find a master who specializes in repairing the electronic keyboard to check it.

Dust falls between the hammer and the circuit board, you take a hair dryer to blow into the crack of the key, if it still doesn't work, let a professional repair, don't open the piano yourself, otherwise if the hammer can't be installed, the whole piano will be wasted!!

First of all, check if it is plugged in and see if the screen is displayed.

If the above examination is normal, if the individual sound is not loud, it may be the following conditions: The service life is long, and the carbon crystal electrode is aging; Dust or other foreign objects ingress; Damage to the crystal diode; Liquids such as water or beverages enter the corroded circuit;

If all the sounds are not loud, you can turn on the demonstration song to see if the screen has rhythm or other changes to display, if not, it is predicted that it is a problem with the motherboard; Check the headphones to see if they're plugged in.

The above situations are predictions, it is best to ask a professional maintenance person to start up and check, and analyze the specific situation, I hope it will be useful to you! Conductive glue under the keys, if you know a little electronic maintenance technology should be easy to get, after disassembling the first use your fingers in some water to press the key that does not sound, see if there is a sound? If there is a sound to explain the problem of conductive adhesive, use a pencil lead to engrave an ink map on the contact point of the conductive adhesive, but it will not take long, if you don't understand the circuit, it is best not to get it yourself, in case the thread is more troublesome.
