How to fix a Yamaha Musical Instrument that won't turn on?
- JJordan VasquezJul 27, 2025
If your Yamaha Musical Instrument isn't turning on, make sure the AC adapter is securely connected to both the DC IN jack on the instrument and the AC outlet. Also, check the batteries. If they are low or dead, replace them with new ones or use recharged Ni-MH batteries, or use the included AC adapter.
