You should have your instrument looked at by an authorized repair center.
And, in general, keep your instrument under a dust cover between uses! Eventually, dust is the enemy of electronic music equipment. It could just be dust, or you may have a cracked board or component... that is why I suggest a visit to an authorized service center - they can tell you for sure.
