"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.

I have onkyo reciever tx-ds898 no sound


Some receivers shut down automatically if a thermal overload is detected or more commonly if speaker impedance is less than specified, i.e, driving a 2 ohm impedance speaker with an output rated for 8 ohms. If you can get the receiver operating long enough, you may see a message indicating why it is shutting down

This can be caused by shorted speakers or speaker wiring, disconnect all the speakers and see if the problem goes away.

The unit is in protect mode because a problem was detected in the output section. In all likelyhood, the output transistors have failed or a secondary power supply hs failed. Because this was the result of a power surge, I would suggest that you take this to a sericer and request a detailed repair estimate. This could be as simple as a voltage regulator gone bad to the microprocessor being fried. This is not a problem that can be diagnosed remotely.
