Need to repair Casio Keyboard model# CTK-451

Dear Sir/Madam,
I am not a dealer but a father trying to fix the daughters keyboard and trying to save some money. We have a Casio keyboard CTK-451 and the AC component on the CCA (the part you plug in the power cord into the keyboard is broke). I have removed the back cover and desoldered the gray square component from the circuit card assy but am having trouble finding the replacement. I have tried Radio Shack but no luck. I hope you know what piece I am trying to describe, apologize for the bad description. Please kindly email me at bobby.thomas@goodrich.com if you findout anymore about this piece part I am looking for. Thank you in advance.

Bobby Thomas from Minnesota, USA.

    I had the same thing happen (daughters, what's a man to do?). Read on a similar post that Casio made their adapter a "unique" size so you have to buy their AD-5 adapter. I'm buying a plug & jack set from Radio Shack as a fix.

The F key near Middle C broke off my CTK 481. Is this something I can fix myself?


Is it broken to pieces or just came off.
I would open up try glue to pieces together and then swap the repaired key F4 with say the (less used) F6 key.

Piano Rhythms not playing in casio ctk 7000


some rhythms have only accompaniment in it. This is not a malfunction I think. And What about this ? This is my problem with casio ctk 7000.. Can you try on the keyboard ? : Hello. I bought a Casio keyboard CTK 7000 two months ago. Firstly I did not notice the problem. But a few days ago I perceived this malfunction; Sometimes when I hit the "INTRO" button during any default (Not user) rhyhms and accompaniment plays, the playing chord is jumping to C chord. For example; When the accompanimet is playing Am chord and I push the "INTRO" button, the keyboard changes the "Am" chord to "C" chord automatically. It always happens when I hit the INTRO button at the just beginning of the measure but not at the middle of the measure. Its troublesome for me, specially during live performance. Can you help and give information about this problem? Thank you very much already now.

Casio CTK-651 keyboard wont switch on


An internal fuse is UNLIKELY.

More likely is either a bad connection/connector at power input or a bad or intermittent power switch.
