How to fix Yamaha A-S2000 Amplifier that fails to turn on?

  Allison KleinAug 17, 2025
  If your Yamaha Amplifier fails to turn on, first, ensure the AC power cable is firmly connected to both the AC IN inlet on the rear panel and the AC wall outlet. If it still doesn't turn on, check the speaker wires for any shorts. If the speaker wires are not touching each other or shorting out against the rear panel of the unit, try turning the power back on. Finally, if the unit has been exposed to a strong external electric shock, turn it off, disconnect the AC power cable, wait 30 seconds, plug it back in, and then use it normally.

  If the Yamaha Amplifier's POWER indicator flashes, it usually indicates that the protection circuitry has been activated due to a short circuit. Check that the speaker wires are not touching each other or shorting out against the rear panel, and then turn the power back on. If the problem persists, disconnect the AC power cable and contact an authorized Yamaha dealer or service center, as there may be an issue with the internal circuitry.

  If you are not getting any sound from your Yamaha Amplifier, check the input and output cable connections to ensure they are properly connected. If the problem continues, the cables may be defective. Make sure that you have selected the appropriate input source using the INPUT selector on the front panel or the remote control. Also, verify that the SPEAKERS switch is in the correct position and that all speaker connections are secure.

  If the remote control for your Yamaha Amplifier isn't working properly, make sure you are within a 6 m (20 ft) range and no more than 30 degrees off-axis from the front panel. Check whether direct sunlight or lighting is interfering with the remote control sensor, and reposition the unit if necessary. Finally, replace all the batteries in the remote control.
