Question about Casio Lighted Keyboard LK90STADMC

Open Question

No sound from Casio LK 45 keyboard's built in speakers. I think a combination of buttons have been pressed by my nephew and it suddenly doesn't produce any sound. Everything else seems fine. I've checked Local Control etc as per manual, but now I'm stumped.

SOURCE: Need replacement key set for Casio LK-110

You would need to call casio for such parts or go to a part store which by googling it you can find the parts for this unit.

SOURCE: 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.

SOURCE: the keyboard works fine but

Read your manual regarding "fingered chords" and similar subjects. It sounds like you are in a single fingered chord mode...

SOURCE: Hi - there is no

There aapparently is no reset proceedure other than cycling the power. You don't tell us if you are on battery or an adapter. Use of incorrect adapter or failing batteries could cause this. The lights run LONG after the batteries will no longer generate sounds. If on an adapter, try using fresh batteries to see if it might work on battery... if it does, then your adpater or the connector may be bad.

How do add songs to the song bank on my Casio LK-30 keyboard?


You can't add songs to the LK-30 song bank. I suspect you would need to take apart the keyboard and replace the ROM (read-only memory) chip to get a different song collection.

Most Casio electronic instrument manuals are available from http://support.casio.com/en/manual/manual.php?cid=008 . However, I found the LK-30 manual at manualslib.com: https://www.manualslib.com/manual/358460/Casio-Lk-30.html .

I wish that I had better news for you.

Why does my keyboard have no sound?


Try using headphones. If it works, then you have a problem with the speakers if you have built in's.

I want to transfer some midi files to my Casio LK-230 keyboard. When I plug in the usb cable it does recognize the casio unit but it does not show up on my computer...like there is not unit... How do...


The keyboard will NOT show up on MY COMPUTER as it does not have memory to record and save MIDI files... It will PLAY them real time as the computer sends the data to the keyboard. You can't transfer and save the files IN the keyboard. Some higher level keyboards do have memory and even hard drives... this one does not. This one will have some built in,that you can play but even those you cannot access as if they were memory.
With the USB cable connected, you should be able to see the device listed in the device manager section of the control panel under system hardware.

My casio lk-45 has no sound, but all the lights work. Could it be the adapter?


Yes it could be. Drop voltage adapter can cause power/pre-amp not work properly, but still can power up the lights.
There maybe power supply circuit failure inside LK45 and also power-amp problem.
