I need a manual for my casio lk30 keyboard - Casio LK30 Note Lighted Keyboard

If it's blown a regulator in the keyboard you may be lucky that that's all that's gone.... If unlucky it could have rippled through & taken out a lot of the electronics. (aka a right off) A decent repair shop should be able to take a look & give you a price to sort it.....

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.

It may due to faulty circuit board of the keyboard. Check for warranty and ask the vendor to replace the keyboard.

Sir, This jack installs on most Casio keyboards to replace broken ones-a common problem. Often the broken jacks have the center connection pin ripped out or loose when the power cord cable has been pulled with a vacuum cleaner or yanked by a pet or child.

A technician is recommended to replace this part on your Casio instrument.

I was also looking for the manual on-line which an e-bay seller told me was available. Not from Casio, but someone was nice enough to scan in a manual at http://www.usersmanualguide.com/casio/musical_instruments/lk-30. It is in PDF format, so you will need to download it and view it with Acrobat reader or similar. Not the greatest quality as it is just a copy, but certainly readable.

try getting a cleaning floppy disk  (the head might be dirty)
hope this helps

It looks like the right one to me. I am ordering one today for our keyboard.

I am going to assume that the leakage was from alkaline batteries. Vinegar will work to clean the residue. This must be done for the electronics to work at the proper voltage....accordianman
