Electronic Keyboard: Teclas não saem som, caixa de som com mal contato

Thu, 02 Jul 2026 15:12:43 -0700

Eu tenho um yamaha psr-185 que ficou muito tempo guardado, quando eu o ligo na tomada e pressiono suas teclas elas não funcionam porém quando eu toco de leve na superfície ao lado da caixa de som sai um barulho muito alto, minha suspeita é que a caixa de som está com mal contato apesar de ambas apresentarem o mesmo problema

Electronic Keyboard: Teclas do piano funcionam após poucos minutos

Sun, 10 Jun 2018 20:31:14 -0700

Tenho um piano digital yamaha p 35. Esse instrumento tem apresentado um problema estranho. Desde dois meses atrás, o intervalo de teclas entre sol-dó da quinta oitava não funciona quando ligo o instrumento e volta a funcionar após alguns minutos ligado. Ou ainda, se eu deixo o piano desligado por uns dias, as teclas voltam a funcionar.

Eu abri o piano e troquei as borrachas de contato e o cabo flat. Fiz a limpeza, mas o problema continua.

Alguém já passou por esse problema ou faz ideia do que pode ser?

Electronic Keyboard: Yamaha PSR E253 has a button that keeps pressing on its own

Tue, 02 Jun 2026 21:52:24 -0700

Hello, there is a button in my keyboard which is the minus button, it presses on its own causing the voice to change continuously/constantly. And another thing is that I can't press other buttons beside it if it does that thing. What do I need to do to fix this?

Casio keyboard: CDP S160 a few keys mysteriously triggering or stopping other keys

Sat, 30 May 2026 12:41:18 -0700

This repair is for a poor customer who's 15 year old lad is so desperate to get it fixed! Yes he confessed to spilling some gooey drink over it! - cleaned carefully first four octaves contacts and PCB board. re graphited the board in places. Cured a dozen keys, BUT C1 + F1# + E2 + C3 + G3# giving very mysterious triggers! ( and these notes well away from where the spillage occured). These five sometimes no sound, then sometimes they all work, BUT when they are all working , holding down C1 + F1# + E2 together - The C1 delays - then double triggered several times sometimes ( whilst all three are continuously held down!) When these 5 x keys decide to work, they all work fine when pressed individually !! How mad is that ??

I know rubber contacts must be okay, swapped them to working parts of keyboard - and the working parts still no problem. Examined all connectors - very few anyway,

motherboard no visual signs of damage or corrosion etc.

Can only think the channels from some keys are interfering with others (short circuit?).

Not knowing how the send signals from each note are clustered together - so hard to prove any short or crossover going on.

. I see some questions here others have had similar problems, - and as yet unresolved?

Electronic Keyboard: Casio WK3700 DSP not working

Wed, 04 Mar 2026 00:55:41 -0700

I have an old Casio WK3700 electronic piano/keyboard.

When powered on in Grand Piano mode 000 it works fine. If I try any other mode the DSP button lights up and it emits a distorted thrumming sound and eventually powers off.

I assume the DSP circuitry is stuffed. Video

Casio CTK-501: Is my Casio Keboard broken? or just the DC Power Supply?

Wed, 07 Jan 2026 18:32:02 -0700

So my Casio CT-600 Keyboard runs a DC 9V Powersupply. My friend accidentally connected it to a 220V Outlet (My keyboard needs only a 110V btw, so it has its own transformer.) After that the Keyboard didn’t work. I was planning to buy a replacement for my DC Power Supply, but before I do, I really need to know what’s broken. Can anyone please answer, I would really appriciate it. Thank you!

My Yamaha P-45 Digital Piano Won’t turn on, I switched the power supply and still it isn’t turning on, I have a feeling I have to switch the internal power supply, but don’t have experience in that and would love some help on what you might think it is,

Electronic Keyboard: Korg Kross 2 - Pitches reversed or not sounding

Fri, 14 Nov 2025 08:32:48 -0700

Keyboard worked great for 4-5 years but this week the notes started playing backwards (high pitches on the left, low pitches on the right). Three keys on the left side don't sound (Bb2-C3). And an octave of keys on the right side (C#6-B6) don't sound.

Each time I turn the keyboard on, it says "Now writing to internal memory" for a few seconds. Then it displays the message "System warning: The internal memory has been corrupted, likely due to an interruption of power while the system was writing/saving data. This has been repaired and the affected Bank has been initialized."

I can't think of when it would have lost power while writing to internal memory. I almost never save anything.

In an attempt to resolve the issue, I upgraded to the latest firmware 1.22 (previously on 1.21). Per the "Restoring the factories settings" section of the manual, I tried "Loading the preloaded data" and "Initializing the system". After each attempt, I got the same results.

Any ideas?

Electronic Keyboard: Problem with yamaha P95 Keyborad

Mon, 05 May 2025 15:02:03 -0700

I'm having an issue with my Yamaha P95. Some keys blast very loud without even touching them when playing some chords. I've been facing this problem for 1 week now. I only bought the piano 3 weeks ago second hand and the first 2 weeks everything was working perfectly fine. I tried to clean all the dust inside the piano but I can't really open the top and reach under the keys. I dont really know if the dust is even a problem or maybe the moist and cold Sydney air. One thing I noticed is that under the keys the is a very creamy texure sticking, almost like vaseline. I really need help as I cant play at all like this. Any assist would be highly appreciated.

Here the problem:
