When I put on the receiver it says Protect, I check my speakers and wire everything is ok, I disconnect the speakers and try it and it says the same thing Protect. what more should I check ?
If the unit does turn without protect without the speakers,
then you just found the cause.
If the unit is still in protect it needs servicing.
Have a tech to guide you if you need to DIY.
Board level troubleshooting is the next thing to do.
these may take some time, but i do hope youll make it.

You are right! There's a good chance you BLEW IT UP, so to speak! But there is hope... [Note: There are no fuses on this unit, inside or out. There IS, however, an internal overload protection system designed to prevent permanent damage. With no disrespect Sony, it is not a very ample system. That is, it simply doesn't do its job very well. However, there is a CHANCE a reputable service center can reset it, but don't get your hopes up.] But before you take it in for service, it is also a REMOTE possibility you will get lucky doing one of the following: FIRST, what happens when you DISCONNECT ALL OF THE SPEAKERS? Does it still go into Protect mode? (If it does, it's time for service.) If not, then you might simply have a bad speaker (rare); a shorted wire; or improper speaker impedence: The NEXT STEP, then, is to make certain ALL of your speakers have an IMPEDENCE of 8 OHMS. Virtually all speakers of even modest quality will include this specification on a label on the back of the speaker. You CANNOT run more than (2) TWO speakers with 4 OHMs impedence on ANY amplifier (technical discussion too long!) Finally, in switching your speakers around for the party, and then again afterwards, you may have crossed a wire; ran a staple through one; or have bare wires touching at one (or more) of the speakers. Check first for bare wires touching one another. This would put your Sony into Protect mode the instant you turn it on. If everything looks okay at the speakers, then reconnect them to the receiver, and test them ONE AT A TIME. For example, reconnect the left front speaker, test the system; THEN add the right front, test the system, and so on, ADDING one more speaker each time - FIRST MAKING SURE EACH OF THEM HAS AN IMPEDENCE OF AT LEAST 8 OHMS! IF there is a short (or bad speaker) this will help isolate it. Assuming the unit powers-up without speakers, then one of these simple fixes might prove worthwhile! GOOD LUCK!
SOURCE: audio protect keeps turning off my receiver (sony STR-DE597)
That is the common symptom of the defected STK-IC in power amp.section
that busted already or just a loose connection.First try to resolder
the pins of STK-IC and also all component parts joint in power amplifier section if its works! if not that is the time you replace
it, so it works normal again.
Hope it may helps you...

Try disconnecting all of your speakers, and then turn on you unit. If you have a defective speaker, or a short in your wires, your unit will go into protect mode. If your unit seems ok with the speakers disconnected, then turn unit off, hook up one of the speaker leads and try it. This way you can isolate the problem.......
Good Luck,
Eric
