Why Yamaha Amplifier fails to turn on?
- B
  Billy LeeAug 19, 2025
  Your Yamaha Amplifier might not be turning on due to a few reasons. First, ensure the power cable is firmly connected to both the AC IN inlet on the rear panel and the AC wall outlet. If that's not the issue, check the speaker wires for any contact with each other or the rear panel, as this could activate the protection circuitry; if a short circuit has occurred, fix the wiring and try turning the unit on again. Lastly, if the unit experienced a strong external electric shock, turn it off, disconnect the power cable for 30 seconds, reconnect it, and then try using it normally.

  Jasmine HoffmanAug 26, 2025
  If the Yamaha Amplifier remote control is not working, make sure you are within a maximum range of 6 m (20 ft) and no more than 30 degrees off-axis from the front panel. Also, ensure that direct sunlight or lighting (from an inverter type of fluorescent lamp, etc.) is not striking the remote control sensor. If these are not the issue, replace all the batteries.
