10 years self taught not great also my casio doesnt sound right.

Hey I bought a used casio for $250 and the treble is quieter than the base clef when played at the same pressure. The treble does not exceed messopiano. Would a factory reset help or was I lowkey scammed?

Also, I can only read very simple hyms in the C key. Chords I can play by ear. If I look at chords on sheet music especially if its not in the C key I panic.
