Psr 330 no sound when playedbut demo works perfect& produces sound

Most likely the keyboard connection is broken. This will need to go to the shop, it's not user fixable.

Why do keys produce no sound?

Hi Kyle:
Have a look at your manual.
Sometimes you'll find that there will be an "input" setting required.
You might also try google with his link.
Hope this helps.

The ACMP function doesnt work when I play, even tho it says it is on in the display window

Check you have selected 'sync start'. The ACMP selection activates the automatic chords but not the rhythm, so each note produces a droning chord. Sync start activates the automatic chords and rhythm you have selected when you play anywhere near the bottom end of the keyboard. Alternatively you can manually press play to start the drums by themselves and then the chords will begin the moment to play with your left hand.

I'd suspect power supply first - filter capacitors may have leaked/dried out. That would be an easy fix for someone familiar.

KORG SP-250. Keyboard powers up, you can change all selections, five or six random notes sound, but the other keys produce no sound at all.

There is probably a cable loose that connects the keyboard itself to the processor... OR the key contacts have been contaminated by spilled liquid. The keys are scanned as a matrix. The contacts will be a conductive rubber pressed against circuit board traces. Clean contact "pills" and the circuit traces with ONLY 99% isoprophyl alcohol.
This is NOT for the unskilled to attempt a DIY other than carefully opening and looking for a cable that has come loose.

Just purchased, certain keys produce no sound

Are the silent keys random or in a pattern (e.g. a group of adjacent notes, every B and G or just all over the place)?
Unless you have got a keyboard split in operation (dividing the keyboard into two separate sections so that you can have a different 'voice' in each part) and have failed to allocate a 'voice' to one of them you have to suspect either a faulty keyboard module or a faulty processor.
If you bought it from new take it back under warranty. Otherwise it will be a job for a qualified engineer with the appropriate test equipment.

Keys not responding on my keyboard.

It needs to be plugged in to a computer with a DAW to produce sound. The DAW converts the information sent by the controller about which key is pressed and how hard and converts it into sound with a virtual instrument

1 key is not producing any sound its D.. n the midde c.. is sumtimes producing a sound n sometime its not.. kindly tell wat has happend to my synth psr i425

Key contacts are dirty. You will have to service the unit. The contacts (two per key) are conductive rubber "pills" that press down on circuit traces under the keys. Use ONLY 99% isoprophyl alcohol and Q Tips to clean both the black pills in the silicone domes and the circuit traces themselves. Be gentle when doing this. When opening the unit, be careful of all the cables as they are easily damaged.

Casio keyboard lit up, no sound, no responses

Unplug for several minutes and try again.

If that doesn't work, look up the "factory reset" procedure for your particular model via google and follow that procedure. It usually involves holding certain buttons down before and during power up.

No Sound

You didn't give any specifics. Possibly it is just broken due to a loose cable to the keyboard (which you could look inside and check) or a burned out semiconductor (harder to check).

If it is a MIDI keyboard, usually symptoms like this are due to a "MIDI Channel ID" problem. It is sending the keyboard on one MIDI channel and whatever is producing the sound is listening on another. For this sort of thing, you can substitute devices to narrow down the problem or try to reset everything, removing all the batteries, if any, and checking the manuals or website for reset instructions. Of course, you may lose stored settings that way.
