What to do if the power indicator is off but the power switch is illuminated on my Crown I-T4000?

  If the Crown Amplifier's power indicator is off, but the power switch is illuminated, it could be due to the amplifier's power switch being off or the amplifier output level being excessively high, causing the power supply circuit breaker to trip. To resolve this, allow the unit to cool down and then reset the circuit breaker located on the back panel.

  If the power indicator and power switch are not illuminated, it indicates a loss of AC power or that the amplifier isn't properly connected. Here's what you should do: 1. Check the power source to ensure it is active. 2. Verify that the amplifier is correctly plugged into the power receptacle. 3. Check the rear-panel breaker and turn it on, if it is off.

Why is the Crown Amplifier power indicator flashing?

  Sandra MitchellAug 25, 2025
  A flashing power indicator means the AC line voltage is outside the acceptable range. Check the AC line voltage to ensure it's within 15% of the rated range.
