      First, ensure the 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 protection circuitry was activated, ensure the speaker wires aren't touching each other or shorting against the rear panel, then try turning the power back on. If the unit experienced a strong electric shock, turn it off, disconnect the power cable, wait 30 seconds, reconnect it, and try again.

      Make sure you are within the remote's operational range of 6 meters (20 feet) and within a 30-degree angle from the front panel. If that's not the issue, try replacing all the batteries.

      The flashing POWER indicator often means 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 of this unit back on. If the issue persists, disconnect the power cable and contact the nearest authorized Yamaha dealer or service center.
