SOURCE: sony str-da90es in protect mode

When these units go into protect mode, they normally have a blown channel. It is not an easy fix, it will require the replacement of a few parts. You would need a multimeter and soldering equipment to determain which parts need to be replaced.

If you would like to fix it yourself let me know and I can help you with it, but it would not be an easy job for you unless you have some experience at troubleshooting electronics.

PROTECT shows every time I turn my reciever on. It's a SONY model #STR-DE335


Turn it OFF. Look for shorted speaker wires or shorted speakers.

None found? Disconnect all speaker wires and try to turn it on.

Turns on ok? One of the speakers/cable pairs is shorted. Check them again.

No good? It's dead. take it to a tech.

Check all of your speaker connections... usually the PROTECT cuts in when speaker wires get crossed or you have blown a speaker.

this PROTECT message also shows if the amp chip(s) have blown in the unit

PROTECT MESSAGE


It senses an error or problem and shuts down. Try disconnecting all the cables and wires attached to it. Try it again. If it still shows protect message, it is an internal fault and requires a repair shop. If it clears up, then the problem may be a shorted speaker wire. Correct the short when reconnecting the speakers.

Monitor show " Protect " can't do anything.


Protect is an indication that one of the output amplifiers is shorted. The unit turns itself off to avoid burning more components. I'd recommend taking it in to a repair facility for replacement of the blown output amp.

"Protect" Flashing


In all likelyhood, one or more output transistors have failed. Please confirm your model as STR-DE335 and I'll post the probable parts that need to be checked.
