Problem with sustain input

[bhl]

Hello!
I would like to ask if somebody here has some sustain solution to a keyboard with the input that was damaged by my little daughter . The rest is working fine .I do not know if there is something like a module with sustain input to connect, or perhaps configure a expression pedal to work like a sustain pedal. Any suggestion will be very appreciated.

The support told that the input has no possibility to be fixed. Only a new mainboard with new inputs.

My instrument is a Kurzweil SP2.

Thanks;

Are you certain it is the input that's fried and not the pedal that's defective? Have you tried it with more than one pedal?

Unfortunately it isn't the pedal. I tested in other keyboard.

Considering the sustain pedal input is a simple switch input it's pretty hard to actually blow one out. Even a dead short is a normal operating condition for that input.

Do you have any idea what your daughter did to the input exactly to fry it?

She put a screwdriver and damaged internally.

Like I said, even a dead short shouldn't have damaged the electronics.

What she may have actually done was simply damage the mechanical jack connector itself. Easy fix with a new connector and a soldering iron.

Otherwise, worst case scenario, it's possible that a static discharge fried an input transistor or buffer IC on the mainboard.

Either way, a GOOD tech should be able to do a component level repair without having to swap out the mainboard.

I'd say phone around the local music shops in your area and get a second opinion from their keyboard techs.

Selling you a new mainboard is like killing ants with a sledgehammer. Overkill.

PS. This is assuming that everything else is working normally as it should.

BTW, I really don't understand how Kurzweil tech support could definitively tell you the motherboard needed swapping from a phone call or an email.

Without looking at the actual hardware nobody could give you a specific diagnosis.

I'm disappointed in this level of support from Kurz. This is not up to their usual standard.

Ok, I will look for a second on maybe third diagnostic. Thanks for the help!

You're very welcome.

Hopefully it is only a damaged connector and won't cost you more than $100

Keep us posted.

I fully agree with Gary. Nobody can diagnose the problem without a physical check and it should not cost too much to have it repaired by a decent tech. I would be happy to tackle it at home, if it were mine.

Another option, give her a few years and your little daughter might just be up to doing the job for you! Starting off with a screwdriver at 2 years of age is impressive.
