Help! My instrumental tuner isn't working...?

Question:I have a Korg TM-40. Whenever I press "Sound" on the left, it only plays A and B flat, and doesn't go up any higher than that.

Also, should it be set to 432 hz?

It should be set to 440 hz. Sounds like your buttons are stuck. You could shoot it with canned air, the kind used for cleaning computer keyboards. Good luck!

Standard tuning is A=440hz not 432. If you want to be in tune with other people you should recalibrate your tuner.

A=440 is the standard. At least, it plays A so just tune that string and do the others manaully. or return the unit for exchange.
