I need de system Reset - Korg SP-250

Hello Geoff, try using an external processor and check that it works well, if so, the problem is that you have the Jack connectors of Effect sending and those of Return of Effects, dirty
Apply a couple of drops of oil, type WD40, to a Plug connector and insert and remove them repeatedly in each connector Jack for sending and returning effects
I hope you can solve the problem, comment the results
Greetings Franco Dosil

Hola Geoff, prueba usando un procesador externo y comprueba que funcione bien, si es asi, el problema es que tienes los conectores Jack de envio de Efecto y los de Retorno de Efectos, sucios
Aplicale en un conector Plug un par de gotas de aceite, tipo WD40 y entralos y sacalos repetidamente en cada conector Jack de envio y retorno de efectos
Espero puedas solucionar el problema, comenta los resultados

Hello John, the fuse is in the power input of Tu Peavey
If you notice, on the rear panel, where the power cord is plugged in, up on the same connector, you will see a horizontal cover that can be removed by placing a tip on the underside of this cover and pulling outwards, it will come out a plastic element, which holds the fuse, this element has an intermediate space where another spare fuse can be housed
I hope my comment has been useful and you can take out the fuse
Keep in mind that if you blow the fuse, because I pass, check the cables and speaker connectors, that do not have any short circuit
Greetings Franco Dosil


Hola John, el fusible se encuentra en la entrada de energ?a de Tu Peavey
Si te fijas, en el panel trasero, donde va enchufado el cable de corriente, arriba en el mismo conector, vas a ver una tapa horizontal que se puede sacar poniendo una punta del lado de abajo de esta tapa y haciendo fuerza hacia afuera, saldr? un elemento pl?stico, que sostiene al fusible, este elemento tiene un espacio intermedio donde se puede alojar otro fusible de repuesto
Espero que te haya servido mi comentario y puedas sacar el fusible
Ten en cuenta que si se quemo el fusible, porque paso,revisa los cables y los conectores de parlante, que no tengan ning?n cortocircuito

Hi Ezra, for the failure you describe, you may have a problem with the Main Insert connectors, more presumably on the left, this connector has the function of interleaving some type of processor in the stages of the master L and R, and has some contacts internal that get dirty and produce false contact in the passage of the output signal
Try cleaning it with some contact cleaner, put a small amount of cleaner and with the help of a plug, put it on and take it out several times in order to make the cleaner work, do the same with the right channel, because the same fault will appear. , sometime
If this does not work, you would apparently have problems with the left master dimmer potentiometer on the corresponding electrical circuit
I sent you the link to download the user manual of your Behringer
I hope you serve my suggestions and manage to make the left exit work
Greetings Franco Dosil

Hola Ezra, por la falla que describes, puedes tener un problema en los conectores Main Insert , mas presisamente en el Izquierdo, este conector tiene la funcion de intercalar algun tipo de procesador en la etapas de los master L y R, y cuenta conunos contactos internos que se ensucian y producen falso contacto en el paso de la se?al de salida
Prueba limpiarlo con algun limpiador de contacto, pon poca cantidad de limpiador y con la ayuda de un plug ve colocandolo y sacandolo repetidas veces a los efectosn de que el limpiador actue, haz lo mismo con el canal derecho, porque ya le aparecera la misma falla, en algun momento
Si esto no da resultado, aparentemente tendrias problemas con el potenciometro atenuador master Izquierdo on el circuito electrico correspondiente
Te envio el link para que descargues el manual de usuario de tu Behringer
Espero te sirvan mis sugerencias y logres hacer funcionar la salida Izquierda
Saludos Franco Dosil

Carlos Hi
despues de formatear el equipo todo tiene que volver como recibistes el pa 500 nuevo de fabrica

soy usuario de un teclado yamaha y queria saber si me pueden enviar las partituras de iniciacion al teclado. gracias mi nombre es Pedro Guardia Berrueco. Mi direccion de E.MAIL: [email protected]. el modelo es psr-E223-YPT-220

Yamaha pianos go through a self test on start up. This could indicate a problem on the main motherboard.

Try a hard reset.

Hold down top C key while turning on.

Wait for it to start up, if it still freezes its time to take it to the repair shop.

i would send it out to the manufactures just to be in the safe side

Scroll down to "get manual" click to download. Ignore other links. The file is compressed and you have to decompress for the different parts. It will open PDF images.

NEVER use de-oxit in a volume control potentiometer !!! Use it ONLY on metal switch contacts.

De-oxit will destroy the lubrication in pots and the resistance element.

You MIGHT try CRC226 which is safe to use. It is available at Home Depot in the electrical dept. Blue can, about $2.75. Make sure it is CRC226 as there are other CRC products there which are not applicable.

The volume control may be damaged now and may need replacement. They are not expensive other than the labor to install it.
