Clear Speaker Terminal Short Circuits

Safety Precautions: Ensure the Denon AVR-X3100W is completely powered off and unplugged from the wall outlet before touching any wiring to prevent electrical shock or damage to the amplifier.

Tools Needed: Wire strippers or small needle-nose pliers.

1. Inspect the back of the receiver where the speaker wires connect to the binding posts.
2. Identify any stray copper strands that have splayed out from the twisted wire bundle and are touching adjacent terminals or the metal chassis.
3. Use needle-nose pliers or your fingers to carefully pull any loose strands away from the metal contact points.
4. If the wire ends are frayed or damaged, use wire strippers to cut off the damaged section and strip approximately 1/2 inch of insulation to expose fresh, clean copper.
5. Re-insert the wires into the binding posts, ensuring the positive and negative leads are securely held within their respective terminals without any protruding strands.
6. Tighten the binding posts firmly to ensure a solid, isolated connection.
7. Verify the fix by plugging the unit back in and powering it on; the red flashing light should no longer appear, indicating the protection mode has been disengaged.
