    Sound used to work beautifully with and without headphones. Haven"t used it for a few years. I must have forgotten how to get sound through the speakers. Lovely sound through headphones. Tried just unplugging them and pressing piano button.

    OK now I have model number I can see this doesn't have this switch. Can you confirm the sound via headphones is playing in both left and right ears. If it is only playing in one ear it could be that you have something stuck in the headphone socket. Often the tip from a plug or adaptor can be left behind. This causes the internal speakers to be bypassed as it "thinks" you want to use on headphones. If it is playing through both ears then this is NOT the case and we need to explore further.

    Try a master reset : With the instrument off : Hold town the top key ( highest sounding ) and turn on. Look at the screen - when it returns to normal release top C. Try and see if this has cleared the fault.

    The next stage would be that damage may have occurred to the amplifier section or something as simple as the speaker have been unplugged or have burnt out. To test this you will need to be confident enough to take your keyboard apart and investigate further.

    See attached picture : GX76undo

    Locate the two speakers and follow the cables back to the main board - ensure they are plugged in - strangely these can work loose in transportation. Connector CNB10 & CNB30

    If you have a multimeter - unplug the cable from the speaker to the main board and measure the resistance across the 2 contacts of the speaker. You should get a reading around 4 ohms.

    If you still haven't solved the problem it is probably an issue with the amplifier chip which will need further investigation by a repair shop.

    I hope this works for you.

Unplug the headphones. check to make sure there is not a switch near the headphone socket which cuts off the speakers, if there is turn it on.

If you still have no sound then it may be an amplifier problem.

Please report back with model number, I may be able to offer more advice.

Why does my lowrey organ not make a sound after I have switched it on?

This is a generic answer for this kind of question.
When there is no sound
Check the obvious.
Is there a light on the organ indicating it is on?
  • Plug it in to a known working wall socket, switch on at the wall
  • Switch on at the organ, check light
  • Very old keyboards need a voice to be selected!!
  • Turn master volume up
  • Turn any other volumes up
  • i.e. lower manual volume
  • upper manual volume
  • swell pedals down
Sometimes a sustain pedal plugged into a volume pedal socket will mute the output, check this.
Headphones out, most headphones will turn speakers off, sometimes the headphone switch can be dodgy, work the headphone plug in an out a few times
There maybe a switch that turns off the speakers, look near the output sockets
Software volumes up, check display, if any.
MIDI instruments, check local control is ON
Still no sound?
Can you hear anything from the speakers?
Hiss or hum usually means the speaker is ok
Total silence may indicate speaker failure, but only if there is one speaker, as in older home organs, or smaller keyboards
Try headphones next, TURN Down master volume first just in case!
If there is some sound, very quiet and gross distortion then possible power amplifier failure.
If your instrument has any kind of line out as well as a headphone jack, try these.
The line output will likely be a pair of phono sockets,like you have on HiFi equipment, 1/4 inch, 6.35mm jacks, like the bigger headphone connector, a 3.5mm socket like the smaller headphone connector, or even a DIN connector on older equipment.
Connect these to the aux (or Line or CD) input on your HiFi, guitar amp or similar. (some times these outputs will drive headphones, usually you will only hear anything in the left side). If this works then it is very likely the power amplifier.
Further tests on MIDI equipped keyboards would be to see if the MIDI does anything.
If MIDI out works and there is no sound, and MIDI in makes a sound this points to local being off, buried somewhere in the menu will be local on or off, make sure it is on.
If MIDI out doesn't work then the failure is likely to be internal power supply or something else critical (not nnecessarily major).
Power amplifier failures in newer, low power, keyboards are often the power amplifier chips (i.c,s), older amplifiers may have just blown their fuses but one or more output transistors may have failed.
Cost of repair will be down to the time it takes to get to the fault, taking these to bits and putting them back can take a lot longer than the repair.!
Hope this helps, Chris the Fader

Why is there no sound from my digital piano and what can I do about

First, re-initalize the piano. The instructions are in your manual or on the manufacturer's website. If that doesn't do it, try the headphone out. If the headphone works but the speakers don't it can just be a dirty jack. However, if none of this works the amplifier board is probably blown and you'll need a repairman.

My amp isn't producing any sound. It works when headphones are in but that's it. Please help

The headphones socket is on the preamp stage - it works so the problem must be after the pre-amp.
Do you get any sound at all from the speakers (hiss or perhaps a click) when you turn it on?
If yes it is an amplifier problem.
Here are some possible causes
  • A wire has come off the loudspeaker - easy to fix
  • Speaker protection fuse has blown - small glass fuse mounted on main amplifier chassis - replace with correct rated and type of fuse (note some of these are 'slow' blow type - important that you get the right one)
  • faulty component in the main amplifier stage - requires attention from qualified repairer
  • Loudspeaker burnt out - this can be tested by connecting another speaker across the terminals of the built in speaker.
  • The headphone jack socket automatically disconnects the loudspeaker when phones are plugged in - it could be that the contact in the headphone jack socket is bent and not re-making contact when the headphones are unplugged.

Sp250 right outout seems to have broken and as a result there is no sound coming from the speakers on the keyboard or through the PA. If we use the left output through the PA - it works, Could you advise...

Check if headphone jack also has right channel dead... If headphones work on both channels, switch contacts on headphone jack MIGHT be the problem.

Peavey minx 110 no sound from main speaker but headphone jack is ok. speaker wires are attached ok.everything on the board appears to be in good shape.amp powers up and all controls work great through...

Inside the headphone jack is a built in switching mechanism. It is there to cut off the sound to the speaker when you are using headphones to practice quietly. For some reason or another it seems as if this is no longer working correctly. One of the causes of this can be bad solder joints on the circuit board where this jack is located. Another cause is a failure of the jack itself. If you are capable, Take the circuit board out and have a look. Hope this helps.
