LK-160 Lighting Up Keys Erratically

[cappyrice]

Hello,

 

So I've had this LK-160 keyboard for a few years now.

 

When recently starting it up again, I've found that when I press a key, this key and a set of other keys light up. Not all of the other keys light up, only a set of keys. This set of keys will vary based on which white key I press. 

 

Even with the music pieces in the piano, when I play them, it lights up sets of other keys than what needs to be pressed.

 

I don't know if its some setting related to the chord of what I press (I don't know much about music).

 

If there's a way to reset this model, that would work too. I wasn't able to find one in the manual or in customer support.

 

I just want to have the key I press light up and nothing else.

 

I would appreciate some help.

 

Thanks.
