Guitar Amplifier: Amplificador Fender Mustang V1 no suena

Thu, 12 Jun 2025 14:15:28 -0700

He comprado un amplificador Fender Mustang V1 que no suena, no sale sonido por el parlante solamente se escucha por la salida de auriculares, ya probé conectándolo a otro parlante he revisado el circuito en busca de corto y lo único que encontré es que entre la etapa de preamp y la etapa de amplificación señal se pierde.

Si alguien ha tenido un problema similar agradecería su ayuda.

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!

Epiphone SG Guitar: How do I prevent my guitar's input jack from loosening?

Fri, 10 Apr 2026 03:47:33 -0700

The input jack on my Epiphone SG electric guitar keeps loosening after several hours of (nonconsecutive) play. I don't want to strip the backing plate screws by removing the plate to tighten the jack once a week! The jack on this model is on the front face of the guitar.

Other than looping the cable through the guitar's strap to prevent excess pressure on the jack, what's a good solution to this problem?

Possible ideas I've thought of include loc-tite (which I'd rather avoid) and replacing the jack's washers with larger diameter ones to prevent the tension from compressing the wood.

Teenage Engineering OP-1: Why won't audio come from the right channel of my OP-1?

Tue, 17 Mar 2026 18:42:12 -0700

I have made sure that all the tracks are panned towards the center, but no audio comes from the right channel. If it is plugged into speakers or headphones and panned to the center, audio only comes from the left side. If it is panned to the right no audio come out. I was curious as to if there is something I am missing or if this is a hardware problem that requires repairs/parts. Thanks!

Teenage Engineering OP-1: Why is my OP-1 not turning on?

Sun, 28 Feb 2021 14:11:54 -0700

I have been storing my OP-1 and using it since 2013. The other week it stopped turning on; currently, when I flip the power switch, I hear the power get to the speaker but the screen does not glow at all. Is this a screen issue, ui issue, or is it something else? It has turned on previously but it only works after I perform a firmware update or sparingly at any other time.
