Electronic Keyboard: Teclado ark 518 54 tecla prende, enciende la pantalla pero no suena

Sun, 03 Nov 2024 17:55:11 -0700

Tengo un teclado ark 518 54 tecla me lo compré en la feria el tema que me pasaron un cargador con la Polaridad incorrecta 9v 300ma y no prendía la pantalla y solo sonaba los parlantes cómo zumbido, me pareció muy extraño pero lo dejé conectado un momento para medir la corriente, pasaron unos minutos y dejaron de sonar los parlantes, después coloqué otro cargador con un poco más de voltaje 12 volts con 4,5 amperes, ahora con ese cargador prende la pantalla pero no suena ningún botón del teclado donde se pueda apreciar que hay un tambor una guitarra o cosas así que puede tener el teclado, cuando tenía conectado el cargador de la polaridad incorrecta noté que un condensador se calentaba mucho ahora mis preguntas.

Qué podré haber quemado? (No salía ningún olor a quemado)

Será que al colocarle más voltaje del que necesita el teclado no suene?

Nota 1: como pueden darse cuenta tengo conocimientos básicos de electrónica pero recurro a este foro para que me ayuden a encontrar la falla.

Nota 2: aparte después probe el cargador con un tester y no da ningún voltaje y se calienta mucho

Electronic Keyboard: keys not working properly

Wed, 17 Aug 2022 05:57:25 -0700

I have a yamaha piagerro npv60. The B & C keys have problems with it. Here's the scenario: - both keys played together, respond to velocity. If you play fast trills or scale, if u hit one first, the next key, either B or C wont sound. You have to time it properly to work. If you hold down either B or C and then press the other... The latter won't sound. But take note, in combination with other notes all is fine. Same issue for the F and F#. This happens in all the B&C and F&F# on the keyboard. Please help! Thanks in advance!

Electronic Keyboard: Yamaha P45 won’t turn off and mutes sounds randomly.

Sun, 23 Jul 2023 10:39:36 -0700

I have a Yamaha P45 digital piano and it’s not turning off when I hold he power button anymore, I have to unplug the adapter. Another thing is that after I start playing, after some minutes the sound stops playing. The power led is on, but no sound is played. This has been going on for quite some time and I haven’t found anything related on the internet, I even tried calling Yamaha but after over 30 minutes on hold I gave up. Any ideas?

Here are the requested images

Electronic Keyboard: Yamaha psr-293 keys and buttons not working

Thu, 01 Feb 2024 11:14:31 -0700

I have a PSR-293 (old) that I turned on for the first time today. I have no knowledge of keyboards and have no idea what could be wrong. I put all the batteries in (completely new and placed in correct direction) turned it on and it was fine but then the keys stopped working out of nowhere. I turned it off and back on and they immediately started working again and the same thing happened. It's after like 1 minute or less that it just stops working and doesn't work again until the next time I turn it on. It was like that until it just stopped working all together, the keys work randomly only after being turned off and on, not everytime it's turned on. The buttons don't work at all no matter what I press, and the screen doesn't say anything, just has the keyboard layout and no words or numbers or anything. The SONG, ESA, STYLE, and VOICE keys light up randomly and the keys only work when SONG and VOICE are both on. I think it's the keyboard itself as the first time I tried turning it on with a cord it didn't do anything AT ALL but if there's a a fix lmk. Idk what to do, please elp.

Electronic Keyboard: Power supply jack needs repair or replacement

Yamaha P-120 S

The power supply jack has become loose, even "jiggles". Is this as easy as replacing the jack, or perhaps soldering whatever is loose? I'd like to know if it's fixable before I tear into it.

Electronic Keyboard: Casio Sk-60 replacing missing on/off button

Wed, 03 Jun 2020 05:30:49 -0700

Hello, i am new here!

I need help with this vintage Casio Sk-60 keyboard, it needs a replacement for that missing (slider) switch. I would love to repair it!

I know how to solder simple things. Adding a lineout or connecting two cables ;) but i am totally lost on this one.

Here you can see on off i prepared for the keyboard. When it will work i will drill a bigger hole for it.

Thats the inside of the keyboard.

And here you can see the part where the switch was. The upper position was (On)

I also found this sceme here, but i dont get it...

I was hoping that maybe someone here sees the solution right away and can help me out. That would be great!

After turning on, my digital piano (Yamaha Clainova CVP 83s) works for some time and then dies with power light off. After a while, the light goes back and works again but then dies. This repeats forever.

I have checked the power supply and changed the power plug of the piano. It does not work. What can I do?
