1. Switch off the piano
2. Make sure the keys are all level at their rest position
3. Switch the piano back on, making sure that none of the keys are touched until the piano is up & running (you may be able to hear a slight click from the piano when it has finished booting up).
The reason for this procedure is that many Yamaha Hybrid Pianos check the key position on boot up to get a reference point for calibrating the sensors. If any of the keys are not in their normal rest position during start up, the processor can lose track of where the keys are when you're playing and may respond incorrectly.
If the piano still has a problem after this, follow Bill's advice and get a technician to have a look at the piano.
