My onkyo reciever (tx-ds656) powers on, then after a couple seconds says "protect" and powers down. why is this happening? [email protected]

"protect" comes on for 4 reasons.

1. crossed or damaged speaker wires- make sure that the positive and negative is not crossed at all. inspect the wiring for any loose strands of wire that might be crossed, touching the speaker frame or touching the metal case of the amp. look for any damage to the wires. use new speaker wires, if you need to.

2. improper speaker ohmage- verify that your speakers are 8 ohms or greater. ohmage is usually labeled on the back of the speaker, and will have the greek letter "Omega" ω next to the ohmage rating. example: 8ω or 16ω.

3. blown speaker- push in on the woofers, it should move freely for an inch or 2 before bottoming out. if it feels like its scratchy or rubbing or there is any resistance before it bottoms out, then the speaker's voice coil is melted.

4. blown amp.
